2 SLOTTED LINER ASSEMBLIES TIGHT LINER ASSEMBLY The Standard Tight Liner Assembly is the simplest method of installing a slotted liner within an oil well casing to serve as a strainer against the passage of sand and other extraneous materials into the production fluid. The liners are substantially smaller in diameter than the casing to provide annular passage of the production fluid radially and upward. The lower end of the slotted liner sits on bottom of the well. The slotted perforations are placed throughout the entire production interval and the liner top is lapped up into the casing with one joint of blank liner. Liner Top Sand Control Adapters (SCA) are used: WORK STRING CASING BUMPER SUB SCA SETTING TOOL 1. as a setting collar for running the liner in the hole on a work string and releasing the liner utilizing a setting tool. 2. as a tool entry guide 3. as an annular seal between the liner top and casing. There are several types of SCA s available for the right application, from simple economical tool entry guides to high temperature, high pressure adapters.

3 SLOTTED LINER ASSEMBLIES LINER TOP ADAPTERS AND PACKERS Chancellor offers several models of Liner Top Sand Control Adapters (SCA) for various applications and down-hole conditions. All of these, except the Plain Liner Top Adapter, incorporate a set seal element for the purpose of preventing formation sands from entering the well bore. In addition to providing an excellent means of sand control, the Chancellor SCA also serves as a liner top tool entry guide. This eliminates any damage as a result of hitting square shoulders when tools enter the liner. The SCA s are also equipped with a safety shoulder to prevent premature setting during run in, and internal locking ring or wicker press to keep seal energized after set. The Chancellor SCA can be combined with a circulating shoe, inner tubing string, and special running thread and clutches for the purpose of circulating and/or rotating in slotted liner. They can be run on liner top as well as in-line or on liner bottom. The Plain Liner top Adapter is the most effi cient and economic means of running a liner where a seal or differential pressure rating is not required. The Model LTPS uses an elastomer to provide a premium liner top seal where seal pressure integrity is most important. The single element LTPS Liner Top Packer with nitrile element can be used for most applications under 250o F and 2000 psi differential pressure. Alternate elastomer materials such as HSN, VITON or AFLAS can be specifi ed depending on higher temperatures of the pressure of H2S of CO2. The three element multi durometer LTP with metal extrusion rings provides a liner top packer with a differential pressure rating of 5000 psi. The LTPS incorporates an internal lock ring that maintains seal integrity after set and release. The LTPS is designed to carry long heavy liners while providing an additional safety set feature that prevents the unintentional setting of the packer while running in the hole. All liner top packers can be optioned with hold down slips and splines for rotating in tension.

4 SLOTTED LINER ASSEMBLIES WITH LINER HANGER At times it is necessary to hang a liner in tension. There are a couple of reasons for this. Either there is no bottom on which to set down and release the liner, or there is suffi cient liner length (1,000 feet or more of liner) that might cause buckling or failure when set on bottom. Hanging a liner versus setting it on bottom will prevent liner buckling when setting liner top seal using reciprocating or beating down. Liner hangers are generally run on the liner top and incorporate a packer seal element. Hold down slips can be incorporated, and various packer seal elements can be provided depending on downhole temperature, pressure, and the concentration of H2S or CO2.

5 SLOTTED LINER ASSEMBLIES LINER HANGERS WITH INTEGRAL PACKERS The Chancellor Model MSCP Mechanical Set Liner Hanger with integral liner top packer is a versatile and economical completion tool. The design is based on an enclosed jay within a one piece sleeve with bow springs. The hanger is mechanically set by manipulating the running-in string. The jay slot holds the slips in place below the cone, while running in the well. When the setting depth is reached, the hanger is raised a few inches and rotated left to disengage the jay slot cage. As the hanger is lowered, slips will be held stationary by the bow springs and the taper cone will move downward under the slips, forcing them outward to contact the casing. Approximately 5,000# downward force will shear cone from mandrel to set packer seal. Slacking off liner weight (approx. 20,000 lb for single element, 40,000 lbs for multi elements) will set the packer element. Reciprocation impact of setting tool may be used to apply additional setting force for shorter, lighter liners or if there is insuffi cient weight. A lock ring keeps the )packer seal energized. Slips are case hardened to grip the hardest casing. Setting tools are released RH rotation when liner is hung, or if necessary, when liner is landed on bottom The MSCP Bottom Hanger is use typically use in casing patch applications for short isolation intervals with a LTP Packer on top or in long cased to surface protective strings. The hanger can be set with RH or LH rotation as needed. The MLTP can be optioned with hold down slips or the Type S metal to metal seal element as well as the 10,000 psi differential pressure MS Packer Element.

This system of drilling-in liners has proven especially benefi cial for liner work over in older, depleted, unconsolidated reservoirs or where returns or sloughing of sand is a problem. The assembly is used for new completions as well as redrills. The mechanical type drill-in adapter has suffi cient torsional strength for most work overs and power swivel uses. The hydraulic drill-in adapter is the preferred assembly for new completions drilled with a rotary table or when high torque and weight are required at the bit for fast drilling. The assembly includes a bit on bottom of the drill-in shoe. A tubing stinger spaced with an expansion joint, and a drill-in adapter on the liner top. With liner on bottom, the setting tools are released, picked up, and the liner is circulated clean. The tools and stinger are pulled out of the hole and a SCA is run in the hole, driven over the adapter and set. 5

7 SLOTTED LINER ASSEMBLIES DRILL-IN/CIRCULATING SHOES AND BALL SEATS The drill-in shoe is used when drilling in a liner with a bit on bottom. Tubing is spaced out within the perforated liner with a stinger joint stabbed through the packoffs and landed just above the flapper check valve. This is to ensure proper delivery of circulating fluid to the bit. A 3 diameter dropping ball is provided to prevent a bailer or other tool from getting stuck in the packoffs. The Chancellor Model CP Circulating Shoe is ideal for circulating soft formation fi ll while running liner in or changing over well bore fluids once on bottom. A bottom ported bull nose is used with optional bladed bottom to assist in the process. The liner and circulating shoe can be rotated while circulating in. A 2-3/8 or 2-7/8 stinger joint is run on the bottom of the inner tubing string and stabbed through the rubber packoffs until landing on top of flapper check valve. The tubing string is properly spaced out with pups so that when the liner top adapter/hanger and setting tools are made up to the liner top, the stinger is always stabbed in pack-off while insuring proper delivery of circulating fluid. A stinger valve can be run to provide circulating ports above the packoffs for the purpose of circulating or reversing without having to pull out the stinger. After release of setting tools with tubing string and stinger, a 3 inch diameter cast steel ball is dropped from surface to land on the pack-off to prevent tubing bailers, etc., from getting stuck in the bore. All internals can be made drillable. The 2S ball seat was designed for use with slotted or uncemented liners for the purpose of providing a port to set a hydraulic changer. The 2S ball seat is typically located at the liner top between a PCPA Packer Cup Mandrel and a Retrievable Packoff Bushing (RPB) or TBR Packoff straddling the hydraulic hanger to be set. The set port is covered by a port piston during run in to prevent inadvertent hanger setting due to high circulating pressures or surges. This is especially benefi cial when running in heavy, sometimes unconditioned, muds where pressure to break circulation can exceed the standard hydraulic hanger set pressure. The setting ball lands on the piston to shear out at 1000 psi to expose the hanger set ports. After hanger set and with tools released, the ball seat piston shears out at 2500 psi to allow for full fluid bypass to circulate a change over after set, this prevents hydraulic lock when pulling out of the packer.

8 SLOTTED LINER ASSEMBLIES HORIZONTAL LINERS-ONE TRIP MECHANICAL Chancellor provides customers with a complete product line for horizontal slotted liner assemblies. Whether it is a simple shallow horizontal or a more challenging extended reach or deeper horizontal, Chancellor has the right tool for the application. The simplest horizontal slotted liner assembly consists of a bullnose guide shoe on bottom with a liner packer on top. The adapter is suffi ciently strong for pushing or pulling the liner while maintaining a seal setting safety position. Circulating or wellbore fluid change over is an option with the addition of the circulating shoe and inner tubing string. Seal setting is done by reciprocal force and setting tool release is accomplished with RH rotation. No rotation is allowed while running in the hole. This simple and effi cient horizontal liner assembly performs quite well for shallow applications.

9 SLOTTED LINER ASSEMBLIES MODEL B, BR, AND BH LINER TOP PACKER The Chancellor Model B Liner Top Packer is a premium liner packer and provides a very dependable seal against gas migration and the passage of sand over the liner top and into the well bore. The packer is made up to the liner and run into the hole and set in one trip. Because of its load rating, the model B liner top packer is an excellent choice for running long, heavy, or deviated liners. A liner tie back receptacle (TBR) is provided which allows future tie back of liner or tubing. The packer is run with a setting tool consisting of a kelly with floating nut, packer setting dog sub and handling lifter. The packer setting dog sub is retained in the TBR while running in the hole so that premature setting of seal is avoided. Once on bottom, the setting tool is released with RH rotation and picked up so that the dog sub is expanded above the TBR. The packer s seal elements are set by slacking off weight. The shear pinned setting ring contains an internal lock ring that keeps the packer seal energized after set. Neoprene, HSN (HNBR), Viton and AFLAS element materials are available depending upon down hole conditions. In addition to Model B features, the Model BR has splines for the purpose of rotating the liner in tension while running in the hole or setting mechanical liner hangers run just below the packer. The splines also prevent the unintended release of setting tools while running in the hole. In addition to Model BR features, the Model BH provides hydraulic straight pull release of the setting tool. This model is especially benefi cial for running horizontal or highly deviated slotted liners where standard mechanical release can sometimes be diffi cult. A secondary mechanical release method is available. The BH s main asset is full rotating ability of liner in tension, compression or neutral while running in the hole. Rotating splines are included that engage the HR setting tool rotating dogs that allow for rotation. Standard packer elements are the choice for lower differential pressures and run in rates. The Single element is rated for 2,000 psi and the three element is rated for 5,000 psi differential pressure. The MS packer element is a high performance liner casing annulus seal with an elastomeric element bonded to a thin wall flaring sleeve. A tapered setting sleeve flares out the MS element providing a tight uniform sealing surface to the casing I.D. Because the element is bonded, the liner can be run in the hole at moderated to fast rates without concern for burning or damaging the element. The element is rated for 10,000 psi differential pressure with up to 10 bbl/min circulating and displacement rates allowed with no damage to the element. 8 MODEL B SINGLE ELEMENT MODEL BR MULTI ELEMENT MODEL BH WITH MS ELEMENT

10 LINER TOP PACKERS MS ELEMENT The MS packer is a high performance liner casing annulus seal with an elastomeric element bonded to a thin wall flaring sleeve. A tapered setting sleeve flares out the MS element providing a tight uniform sealing surface to the casing I.D. Because the element is bonded, the liner can be run in the hole at moderated to fast rates without concern for burning or damaging the element. Up to 10 bbl/ min circulating and displacement rates are allowed with no damage to the element. The MS element is used for cemented as well as uncemented liner completions. It has become Chancellor s packer of choice for its most effective and reliable performance.

11 SLOTTED LINER ASSEMBLIES MODEL S STEEL SEAL SAND CONTROL ADAPTER (SCA) The Chancellor Steel Seal Sand Control Adapters are a superior choice for providing a secure annulus seal between the production liner and the well casing in thermal applications. The seal element is machined from ductile steel and forms a thin wall metal to metal annular seal. When set, the sealing ring provides a natural downward facing cup that is designed to facilitate retrieval. The setting tool running nut is engaged to the adapter in a safety position while running in or driving over a liner top. In this position premature setting of the seal is prevented if an obstruction is encountered. The setting procedure is similar to that of any other common liner top adapters. 10,000 lbs is suffi cient weight to set the seal. DRIVE OVER TYPE The Chancellor Steel Seal Sand Control Adapters work remarkably well for thermal wells where liner expansion/contraction and steam cutting often cause other seal elements to fail. The metal seal element will maintain a full circle seal through such cycles. The seal has fi eld tested to 1200 psi. U.S. Patent No. 4,796,786 has been given to this invention. The original Steel Flare Sand Control Adapter was designed and developed in the 60 s when steam flood was fi rst introduced for enhanced recovery of heavy crude. This SCA has been continually improved over the years. The most recent design is the Model S. Because of its simple design, it is economical and effi cient to use. The Model S was designed to be an all weight size and is very easy to set. The S steel element can be set on tubing. no drill collars are required. The Model S has a reduced O.D. and is a good choice when circulating is required or tight spots in the casing are anticipated.

A simple landing nipple is run on the liner top and has suffi cient strength for pushing or pulling the liner. The landing nipple provides maximum annular area for circulating. It has rigid centralizers to maintain liner top concentrically for the purpose of driving over the sand control adapter (SCA). After landing the liner on bottom, the setting tools are released with RH rotation and pulled out of the hole along with the inner tubing string. If it is necessary, the hydraulic drill-in adapter can be run on the liner top instead of the landing nipple. This option provides the ability to rotate the liner in tension or compression while running in the hole. Another advantage of the hydraulic adapter is that the setting tool remains engaged and locked to the liner top while running in the hole, preventing unintentional release of liner. Once on bottom, a setting ball is dropped to shear out and release the drive dogs. The setting tool is then released with RH rotation. 11

13 SLOTTED LINER ASSEMBLIES DRILL-IN ADAPTER The Chancellor hydraulic drill-in adapter was developed to improve upon the limitations of the conventional right hand clutched drill-in adapter. It was specifi cally designed for excessive torque (in excess of 3000 ft-lbs) that indicated down hole conditions such as inadequate circulation rate or mixture, dog legs or deviations from straight hole drilling, or certain formations that make drilling diffi cult. The hydraulic drill-in adapter is highly recommended for new or workover drill-ins where no pilot hole has been made. THE FEATURES INCLUDE: > A maximum drilling torque of up to 15,000 ft-lbs. > A completely sealed setting tool to preclude the passage of fi ne sands into the hydraulic components of the setting tool. > Right hand rotation release for setting tool. > A fail safe hydraulic release for drive mechanism. Upon reaching T.D. a ball is dropped to shear out the piston to retract drive dogs. > Ability to drill-in with any circulation fluid. Ability to function equally well for drilling in blank liners to be cemented. > Bypass ports in hydraulic release piston to allow for continues circulation thru tubing after shearing out and releasing. > Simplicity and fail-safe operation is compatible with standard drill-in practice and equipment. The hydraulic setting tool and drillin adapter are delivered to rig site as a complete unit with drive dogs of setting tool in the mating grooves of the drill-in adapter. MECHANICAL DRILL-IN ADAPTER MECHANICAL SETTING TOOL HYDRAULIC DRILL-IN ADAPTER HYDRAULIC SETTING TOOL The Chancellor mechanical drill-in adapter is a liner top adapter clutched for RH rotation. It was designed specifi cally for transferring torque from the drill string through the liner assembly down to the shoe or bit. The rotating clutch surfaces between the adapter and the setting tool provide suffi cient surface area to withstand most conditions (to 3000 ft-lbs). Since there is no make up between the setting tool and adapter clutches, left hand release of the setting tool is no problem. 12

14 SLOTTED LINER ASSEMBLIES HORIZONTAL LINERS - HYDRAULIC SET AND RELEASE The Chancellor Hydraulic Set and Release Horizontal Liner Assembly was designed specifi cally for running long horizontal or highly deviated slotted liners. It utilizes the model HH setting tool which features complete hydraulic packer setting and hydraulic straight pull release where mechanical setting and release is sometimes diffi cult or impossible. The liner can be circulated while running in the hole as well as rotated while in tension or compression. The setting tool remains engaged to the hanger at all times while running in the hole. A mechanical emergency release is available with RH rotation. The hydraulic release feature of the HR tool can be combined with a mechanical (weight set) packer dog sub to simplify the setting procedure when down hole conditions allow it.

15 CEMENTED/SLOTTED LINER ASSEMBLIES TYPE HR SETTING TOOL The Chancellor Type HR Setting Tool is designed for running horizontal or highly deviated cemented or perforated liners with Chancellor Hydraulic Set Liner Hangers with Setting Collars or Liner Top Packers. The Type HR hydraulic setting tool features complete hydraulic liner hanger setting and hydraulic straight pull release where mechanical release is sometimes diffi cult or impossible. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. The dogs can re-engage the splines after setting tool release for rotating the liner during cementing if required. The hydraulic release shear pressure is adjustable to allow for a wide variety of running conditions and applications. The Type HR Setting Tool features a collet nut and piston mechanism that locks the tool into place coupled with a rotating dog sub to prevent unintended release of the tool and transfer torque to liner. When the HR piston is sheared at approximately psi, the setting tool can be released with straight pick up. A mechanical secondary release is available with a 1/4 turn LH rotation followed by a 1/2 foot slack off. The Type HR Setting Tool can also be combined with a Rotating Packer Dog Dub (RPDS) used to set liner top packers. The HR can also be optioned with a Slick Joint and Retrievable Packoff Bushing (RPB) system as required for cemented liners. For slotted liners, the HR tool is combined with a PCPA cup tool and 2S ball seat as needed for providing the chamber and port for setting the hydraulic hanger and releasing the HR tool. The HR tool is pressure tested before each run. MODEL HR 14

16 SLOTTED LINER ASSEMBLIES TYPE EHRSL SETTING TOOL The Chancellor Type EHRSL Slotted Liner Setting Tool is designed for running horizontal or highly deviated slotted liners with Chancellor Hydraulic Set Liner Hangers with Liner Top Packers. The HR hydraulic setting tool features complete hydraulic liner hanger setting and hydraulic straight pull release where mechanical release is sometimes diffi cult or impossible. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. The system includes the 2S ball seat that offers complete isolation of the hydraulic hanger and HR setting tool during run in to allow for high circulating pressures without the risk of setting the hanger or releasing the setting tool. The Slick Joint and Retrievable Packoff Bushing (RPB) allow for packer testing after set. After tagging bottom, the liner is picked up to circulate. A setting ball is dropped down the drill pipe and conventionally pumped to seat at the 2S Ball Seat. Pressuring up to 1200 psi opens the set ports and sets the hydraulic liner hanger. After slacking off weight to confi rm hanger set, pressure is increased to 2200 psi to release the HR setting tool. This allows the setting tool to be released with straight pick up. A mechanical secondary release is available with a 1/4 turn LH rotation followed by 1/2 foot slack off. The 2S ball seat shears out at psi. The PCPA cup packer is run below the 2S ball seat and features two sets of up and down cup to isolate the hanger and setting tool against surge pressures during run in. The Type HR Setting Tool is combined with the Rotating Packer Setting Dog Sub (RPDS) used to weight set the liner top packer after release of setting tool. The packer dog segments collapse and reside in the TBR while running the liner in the hole. In this run position there is virtually no way to accidentally set the packer. After tagging bottom and pumping a change over, with the hanger set and the setting tool released, the setting tool is picked up so that the RPDS clears the top of the TBR. The dog segments are now expanded and can be used to apply weight to set the liner top packer. The RPDS has a journal bearing that allows the packer weight to be rotated in. This is especially benefi cial in highly deviated or horizontal applications. A 40,000 lb shear indicator is provided to verify that weight was applied to the packer. MODEL HTP 15 TYPE EHRSL

17 HORIZONTAL SLOTTED LINER ASSEMBLIES MODEL HS STEEL THERMAL LINER PACKER When running long horizontal or highly deviated slotted liners in steam flood applications, Chancellor recommends the model HS Steel Seal Liner Top Packer with the Model HLTP Hydraulic Setting Tool and the Model HR Hydraulic Release tool. These hydraulic setting tools feature complete hydraulic packer setting and hydraulic straight pull release where mechanical setting and release is sometimes diffi cult or impossible. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. The HS Liner Top Packer works remarkably well for thermal wells where liner expansion and contraction and steam cutting often cause other seal elements to fail. The metal to metal seal element will maintain a full circle contact seal through such cycles. The seal has been fi eld tested to 1200 psi. The HS can also be provided with hanger or hold down slips. U.S. Patent No. 4,796,786 has been given to this invention. The HS Liner Top Packer with the HR//HLTP setting tool can be run in assembly with a circulating shoe and inner tubing string providing for the ability to circulate while running in the hole or well bore change before and/or after the Packer seal element is set. After circulating, a setting ball is dropped down the drill pipe and conventionally pumped to hydraulically set the liner top packer. The ball lands in a seat below the packer or within the the tubing string. The hanger/packer starts to set at 1000 Psi. The setting tool releases at 2000 Psi Psi will put suffi cient setting force (43,000 lbs for 9 5/8 ) on the packer element Psi shears the ball seat to allow for bypass circulation. The setting tools are released with straight pick up. A mechanical emergency release is available with LH rotation. Conventional circulation can resume after set and release.

18 THERMAL EXPANSION JOINTS MODEL PS AND MODEL CEJ Chancellor offers tubing and casing expansion joints for use in thermal applications to allow for free expansion and contraction movement of the tubing or liner string during injection or production operations. The expansion joints can also be used to allow for expansion stroke when tubing or liner packers are anchored below. The standard expansion joint allows for free swivel throughout the expansion stroke. Fully clutched expansion joints are available for the purpose of transferring torque through the entire stroke in tension, compression or neutral. A key and key way are provided that allow for this rotation. Seals are selected for the specifi c application from low temperature (250 degrees F) up to high temperatures (600 degrees F). Differential pressure ratings are 5000 psi standard. Expansion joint stroke is three foot standard with lengths up to twenty feet available. The Casing Expansion Joint can also be used as a Casing Adjuster to assist with getting the casing to bottom in highly deviated wells. When the casing hits a tight spot or build up, the casing expansion joint is used as a bumper sub to assist in pushing the casing thru. Another use for the Casing Expansion Joint is to run on top of a cemented casing string when cement is not expected to return to the surface. The uncemented casing will expand and contract in thermal cycles thru the expansion joint and not cause damage to the casing or the well head at surface.

19 COMPLETION PACKER ASSEMBLIES MODEL TS THERMAL RING SEAL The Chancellor Model TS Ring Seal Packer is used in steam injection applications. It was developed specifi cally as an alternative to the conventional thermal packer with expansion joint. The TS Ring Seal packer design is simple, effi cient, and very economic. The design is based on metal to metal press contact with the casing I.D. The dual split seal rings are machined from a mild steel and heat treated to a spring rate. The gap in the rings allow for radial movement and are out of phase from the other. The rings act similar to piston rings as they pass freely through casing collars. By design, the TS Ring Seal Packer will move freely with the expansion and contraction as required of thermal systems. The packer runs in the hole with a slight drag and can pass at a minimum casing drift I.D. There are no slips or elements to set. The seal rings are self energizing. Field tests indicate a high effi ciency when compared to exotic high temperature elastomeric packers and cup tools. The ring seal packers are generally run in sets of two to isolate the intended zones. They have a life of the completion service rating but can be redressed if necessary. A high temperature cup packer can be run in combination with the ring seal packer if pressure integrity is required for isolation.

21 GRAVEL PACKED LINER OVER THE TOP AND ROTATING PORT COLLAR TOOLS Gravel packing is a systematical process designed to further control unconsolidated sand formations from entering the well bore. This utilization of gravel as a controlled fi ltering device was fi rst introduced to the oil industry in the 1930 s. Since then techniques and methods have been refi ned and designed to fi t special requirements. Chancellor s involvement with gravel packing is primarily the manufacture and sales of liner assembly and setting tools as required for the common techniques. These gravel pack systems are part of Chancellor s broad capabilities. The conventional method or, over the top, technique is very common for the shallow heavy crude formations. This simple method may utilize fresh or KCL water, polymers or foam as the carrying fluid. Slotted liner is run in the hole with a landing nipple on top. An open ended tubing string is run inside the liner and connected to the over the top tool (or combination tool). The liner is run in on drill string. Gravel is pumped down the drill string, out gravel ports located below a dual set of packer cups and over the top of the liner. Gravel packs around the liner and a pack off occurs when gravel covers the slots. Excess gravel is then reversed out and the gravel pack tools and tubing are released and pulled out of the hole. A drive over adapter is run and set to seal off the liner/casing annulus. Port collars are typically used to gravel pack longer liners. Staging the pack from two or more port collars helps to prevent packing off early. Port collars can also be installed above the zone to receive gravel, if there is a signifi cant amount of blank liner above the slotted liner, to avoid unnecessary hole under reaming. The port collar is capable of handling all types of gravel. The combination gravel pack tool is picked up to locate and straddle the port. After pack off, the port is closed and excess gravel is reversed out. When multiple port collars are run, the setting tool is moved up to locate the next port collar and the gravel pack process is repeated. LANDING NIPPLE ROTATING PORT COLLAR The inner rotating sleeve is sealed with O-rings above and below the gravel ports (2). O-ring side seals can be added to the rotating sleeve around the port to provide a pressure tight seal when closed. Rotating splines are deep so that the gravel pack key tool remains engaged during rotation. The sleeve is opened with LH rotation and closed with RH rotation. A steel pin and mill groove positively locate the open and closed port positions. This limits the rotation to 90º from stop to stop. 20 OVER THE TOP GRAVEL PACK TOOL STANDARD PORT COLLAR GRAVEL PACK TOOL

23 GRAVEL PACKED LINER MODEL DP1 DRILL-IN ADAPTER Chancellor Drill Pak is a method of drilling in a liner and gravel packing down the backside in one trip. These tools were developed by combining Chancellor s tight Drillin liner assembly with a stinger and backup circulating valve, and modifying the hydraulic drill-in adapter with circulating ports. The Drill Pak assembly can be made up with a bit or under reamer (optional) on bottom. The liner is drilled in to depth using foam, mud, or other drilling fluids. Normal drilling procedures apply. With the liner on bottom, and the hole changed over, the fi rst setting ball is dropped to open up the bottom stinger valve. Reverse circulating is established followed by normal gravel packing procedures. After gravel pack is complete, the releasing ball is dropped down the drill pipe to release the DP1 hydraulic setting tool. Ports are now open to circulate excess gravel off liner top. The setting tools are pulled out of the hole, and the drive over Sand Control Adapter is run to seal off the casing/liner annulus. The Chancellor Model DP1 Hydraulic Drill-in Adapter was developed to drill in the liner and circulate excess gravel after the backside pack is complete. It was specifi cally designed for excessive torque. THE FEATURES INCLUDE: > A maximum drilling torque of up to 15,000 ft-lbs. > A completely sealed setting tool to preclude the passage of fi ne sands into the hydraulic components of the setting tool. > Right hand rotation release for setting tool. > A fail safe hydraulic release for drive mechanism. Upon reaching T.D. a ball is dropped to shear out the piston to retract drive dogs and open circulating ports. > Ability to drill-in with any circulation fluid. > Simplicity and fail-safe operation is compatible with standard drill-in practice and equipment. The hydraulic setting tool and drill-in adapter are delivered to rig site as a complete unit with drive dogs of setting tool in the mating grooves of the drill-in adapter.

25 CEMENTED LINER ASSEMBLIES MECHANICAL LINER HANGERS The Chancellor Mechanical set liner hanger is a versatile and economical completion tool. The design is based on an enclosed jay within a one piece sleeve with friction springs. The hanger is mechanically set by manipulating the running-in string. The jay slot holds the slips in place below the taper cone while running in the well. When setting depth is reached, the hanger is picked up a couple feet and rotated (either right or left hand depending on application). As the hanger is lowered, the slips will be held stationary by the friction springs and the taper cone contacts he slips and forces them outward into the casing. Slips are carburized to grip the hardest casing. The simple jay mechanical design allows the operator to set and release the hanger any number of times if necessary. The hanger is run in combination with a separate or integral setting collar or liner top packer. The model MSC mechanical set single cone liner hanger is ideal for short and medium length liners. The model MDC dual cone hanger effectively doubles the hanger capacity of the MSC which is the choice for medium to long heavy liners. Both models offer unrestricted bypass circulation before and after set. The MSC can be optioned with an integral setting collar running box (model MSCRB) when running short shallow liners that can be set with LH rotation and RH release of setting tool. The Chancellor liner Swivel is normally used when running mechanical set liners in highly deviated wells in which rotating to set the liner may be a problem. The swivel allows rotation of the hanger without having to rotate the total liner. A clutch system in the swivel (feature may be deleted if required) allows easy release of the running nut from the liner, if the liner has to be set on bottom. MODEL MDC MODEL MSC SWIVEL 24

27 CEMENTED LINER ASSEMBLIES HYDRAULIC LINER HANGERS The Chancellor Model HSC Hydraulic Liner Hanger is the correct choice for hanging and cementing in from short weight through medium length liners. The design is primarily based on the hydraulic setting of the slip segments (four total) which distribute the liner weight evenly on the tapered oval cone. The cone is mill grooved and staggered to allow optimal circulation around hanger. The hydraulic set is ideally suited for highly deviated holes at any depth where liner rotation can not effectively set a mechanical type hanger. The model HDC hydraulic dual cone hanger has twice the slip area and load capacity as the HSC and is well suited for long heavy liners. Six slips distribute weight evenly on two tapered cones. The Model HTP Hydraulic set Double Grip Liner Top Packer is ideal for use in horizontal or highly deviated or deep slotted liners, where hydraulic setting of hanger slips is necessary. The slips hang as well as hold the liner in place and prevent movement up or down the hole. The hydraulic liner hanger may be set before or after cementing by applying pressure to the running-in string. The hydraulic slip piston is shear pinned to avoid premature setting. The hydraulic liner hanger may be reciprocated during cementing and set after cementing by applying hydraulic pressure against the liner wiper plug after it is landed in a Model WP landing Collar. To set the hanger before cementing, a Model H Landing Collar with setting ball must run. MODEL HSC MODEL HDC MODEL HTP 26

28 CEMENTED LINER ASSEMBLIES SETTING COLLARS All Chancellor setting collars are typically run above the liner hanger for the purpose of carrying the liner weight and engagement of the setting tool while running-in the hole. They also serve as a tool entry guide after completion. The Plain Liner top Adapter is the most effi cient and economic means of running a liner where a seal or differential pressure rating is not required. The Model A is a simple and economical choice for RH release. The model AR has splines which offer RH setting (or rotation) of liner in tension as well as RH release with the use of a rotating dog sub. PLAIN LINER TOP ADAPTER 27 MODEL A MODEL AR

29 CEMENTED LINER ASSEMBLIES SETTING COLLARS Chancellor setting collars perform several functions with various options available. All models illustrated here are run above the liner hanger for the purpose of carrying liner weight and providing a RH release of setting tools. While maintaining a smooth entry tool guide following completion. A tie back receptacle (TBR) is standard for optimal installation of a tie back packer or seal nipple. Along with the TBR, the Model BR Setting Collar is provided with splines designed for rotating the liner in tension. Splines and a rotating dog sub can be used when RH setting and RH release of the mechanical liner hanger is required. These splines ensure that the setting tool will not release while running in the hole. In addition to these features, the Model D provides a retrievable pack off bushing (RPB) profi le when cementing using the RPB in the setting tool. It is designed for rotating the liner in tension. Use of the RPB and slick joint signifi cantly reduces the upward hydraulic forces characteristic of the packer cup pack off and eliminates the need for drill out as required for the drillable pack off bushing (DPB). The Model E shares the same features as the Model D without the RPB profi le. A DPB is used when cementing. This setting collar is effective for horizontal or deviated slotted liner applications as well. Since it is not advised to push and rotate liner in compression, the Model DHR has a special thread form that is designed to hydraulically release with the type HR hydraulic setting tool. The HR hydraulic setting tool features complete hydraulic liner hanger setting and hydraulic straight pull release where mechanical release is sometimes diffi cult or impossible as well as a secondary mechanical release back up option. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. MODEL D MODEL E MODEL DHR MODEL BR 28

31 CEMENTED LINER ASSEMBLIES ROTATING LINER HANGERS Chancellor Rotating Liner Hangers initially hang the liner in tension and then provide a means to rotate the liner during cement operations, ensuring a more complete cement bond. The design is primarily based on the setting of the slip segments which distribute the liner weight evenly on the tapered swivel cone. The cone is mill grooved to allow optimal circulation around hanger. After setting, the hanger mandrel and liner below can rotate through stationary slips and swivel cone. This is possible by means of a specially engineered high strength tapered roller bearing which is contacted by bearing surfaces on the cone and top collar. The bearing and races are covered and sealed to prevent contamination. The rotation capacity of this bearing design is very effi cient and economical and well suited for rotating moderate to heavy liner loads with normal torque during cementing operations. All rotating liner hangers are combined with a double splined setting collar or liner top packer and setting tool with rotating dog sub for transferring torque. The Model HSCR single cone hydraulic set liner hanger and Model HDCR hydraulic set dual cone liner hanger are ideally suited for deep or deviated liners. The hydraulic setting is done by applying pressure to the run-in string. A setting ball and Model H Landing Collar are used. The Hydraulic Piston is shear pinned to avoid premature setting. The Model MSCR mechanical set single cone rotating liner hanger and Model MDCR mechanical set dual cone rotating liner hanger are very effi cient and economical choices for shallow to medium depth vertical wells where RH setting is not a problem. 30 MODEL HSCR MODEL HDCR MODEL MSCR MODEL MDCR

33 CEMENTED LINER ASSEMBLIES LINER TOP PACKERS Chancellor Liner Top packers are run with or without a liner hanger below and perform several functions with various options available. All models provide a square thread running box for the purpose of carrying liner weight and providing RH release of setting tools. A smooth tool entry guide is maintained following completion. All packer seal elements are weight set. The Model B liner top packer (and all models) has a tie back receptacle (TBR) that serves to retain the packer setting dog sub while running in the hole, preventing premature setting, as well as to provide for future liner tie back. The Model D is additionally equipped with a retrievable packoff bushing profi le and splines for rotating the liner while running in the hole or for right hand set mechanical liner hangers. The splines also keep the setting tool locked on, preventing unintentional release. The Model E liner top packer has all these features including hold down slips to prevent short liners from moving up the hole. Since it is not advised to push and rotate liner in compression, the Model DHR has a special thread form that is designed to hydraulically release with the type HR hydraulic setting tool. The HR hydraulic setting tool features complete hydraulic liner hanger setting and hydraulic straight pull release where mechanical release is sometimes diffi cult or impossible as well as a secondary mechanical release back up option. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. MODEL B The packer seal confi guration can be a one piece single sleeve, a three unit multi durometer packer, or a MS packer element. The MS packer element is a high performance liner casing annulus seal with an elastomeric element bonded to a thin wall flaring sleeve. A tapered setting sleeve flares out the MS element providing a tight uniform sealing surface to the casing I.D. Because the element is bonded, the liner can be run in the hole at moderated to fast rates without concern for burning or damaging the element. The element is rated for 10,000 psi differential pressure with up to 10 bbl/min circulating and displacement rates allowed with no damage to the element. Neoprene, HSN, Viton and AFLAS materials are available depending upon down hole conditions. Extension rings help maintain seal and integrity during high pressure conditions. A shear pinned setting ring that contains an internal lock ring keeps the packer seal energized after after set. 32 MODEL DHR MODEL D MODEL E

35 CEMENTED LINER ASSEMBLIES LINER TOP TIE BACK PACKER The Chancellor Model HLTP Liner Top Tie Back Packer is a high performance hydraulic set liner top isolation packer. The HLTP is run after the liner is cemented, running tools are retrieved, and a polish mill is run to clean out existing tie back receptacle. The hydraulic setting tool delivers the force necessary to set the packer elements. Hold down slips prevent the packer from creeping up the hole. The hydraulic setting feature allows the packer to set even if there has been damage to the existing tie back receptacle. Another advantage that the hydraulic feature provides is in delivering the full setting force to the packer elements. This is especially benefi cial in deviated and/or deep wells where the full setting force of a weight set packer is sometimes not delivered. The Chancellor Model MLTP is a more economical and effi cient Liner Top Tie Back packer and is used on most vertical well applications where weight set of packer and hold down slips is not a problem. The packer seal confi guration can be a three unit multi durometer packer or a MS packer element. The MS packer element is a high performance liner casing annulus seal with an elastomeric element bonded to a thin wall flaring sleeve. A tapered setting sleeve flares out the MS element providing a tight uniform sealing surface to the casing I.D. Because the element is bonded, the liner can be run in the hole at moderated to fast rates without concern for burning or damaging the element. The element is rated for 10,000 psi differential pressure with up to 10 bbl/min circulating and displacement rates allowed with no damage to the element. Neoprene, HSN, Viton, and AFLAS materials are available depending upon down hole conditions. Extrusion rings help maintain seal integrity during high pressure conditions. A shear pinned setting ring that contains an internal lock ring keeps the packer seal energized after after set. MODEL HLTP AND SETTING TOOL 34 MODEL MLTP AND SETTING TOOL

36 CEMENTED LINER ASSEMBLIES LANDING COLLARS The Chancellor Model WP Landing Collar provides a latch down seat and seal for the liner wiper plug, and provides an additional back up to the float collar and/or the float shoe to ensure that cement remains in place after displacement. The landing collar is normally run one or two joints above the float shoe or just above the float collar. The Model WP landing Collar is run for either mechanical liner hangers or adapters, and also used with hydraulic set liner hangers when it is desirable to reciprocate or rotate the liner while cementing prior to setting the liner hanger T651 aluminum alloy is used internally and is easily drillable. The Chancellor Model H Landing Collar is run in the liner assembly when it is necessary to set a hydraulic hanger before cementing. This landing collar provides a seat shear assembly that allows for suffi cient differential pressure to be built up against it to activate the hydraulic hanger prior to cementing. The landing collar contains a ball seat that is pinned to shear out at approximately 1000 psi above pressure required to set hanger. Circulation is not restricted once the ball seat is sheared. MODEL WP MODEL H The PC equipment was designed for use with premium or flush joint liner connections. The landing collars are held in place with threaded retainer rings and have seals that add reliability and ensure effective back pressure sealing. MODEL PCWP 35 MODEL PCH

37 CEMENTED LINER ASSEMBLIES FLOAT EQUIPMENT Chancellor Float Equipment features a spring loaded ball that provides optimum assurance that the cement volume pumped around the liner remains in place. The shoe s aluminum guide nose contains interval fi ns that direct the flow of cement evenly for a better cement job. Bottom and side ports (3) are standard. The valve is a spring loaded ball type. The ball is made of high density phenolic for strength and resistance to abrasion, even when subjected to long periods of pumping abrasive materials. The ball seat, a rubber o-ring located in an aluminum disk, is designed to be out of the flow path for circulating fluids so it can t wash out. The ball is guided into the seat by aluminum fi ns which are an integral part of the float shoe. The fi ns not only guide the ball, but also direct the flow of cement around the shoe for a better cementing job. Differential pressure is up to 5000 psi. PC FLOAT COLLAR PC FLOAT SHOE The PC equipment was designed for use with premium or flush joint liner connections.

38 CEMENTED LINER ASSEMBLIES DRILL PIPE DART AND LINER WIPER PLUG The Chancellor Model JM Liner Wiper Plug is used to effectively displace cement within the liner. After a volume of cement has been pumped, the drill pipe dart is released from the cementing head followed by displacement fluid. The drill pipe dart will latch and seal into the liner wiper plug. The tandem unit is then shear released from the setting tool to further displace the liner to latch and seal into the landing collar. The latch and seal system will provide additional back pressure safety to the float equipment to ensure that cement remains in place after displacement. All materials are easily drilled out after cementing. The Chancellor Model TS4 Drill Pipe Dart is used to effectively displace cement within the drill pipe. The TS4 was specifi cally designed to displace a combination drill string from 2-7/8 through 5-1/2 Drill Pipe. The Model C5 Drill Pipe Dart is the standard for heavy duty cement displacement. After a volume of cement has been pumped, the drill pipe dart is released from the cementing head followed by displacement fluid. The drill pipe dart will latch and seal into the liner wiper plug. This tandem unit is then shear released from the setting tool to further displace the liner to latch and seal into the landing collar. The latch and seal system will provide additional back pressure safety to the float equipment to ensure that cement remains in place after displacement. All materials are easily drilled out after cementing. TS4 DRILL PIPE DART C5 DRILL PIPE DART MODEL JM LINER WIPER PLUG 37

39 CEMENTED LINER ASSEMBLIES CEMENTING PACKER SHOE The Chancellor Cementing Packer Shoe is designed to effectively isolate perforated, slotted, or damaged liner below from cement contamination. When set, the packer seal element retains the cement above the shoe and assures a sea between the casing and inner liner. The Model BC Packer Shoe is the most effi cient and simple method. The BC contains two casing packer cups placed below drilled cementing ports with a blank drillable baffle below to hold the column of cement. A float insert or collar is run above the packer shoe to ensure that cement remains in place. There is no mechanical setting procedure required. This method is not recommended for running at great depth or through bad order casing. The Model HPS Hydraulic Cementing Packer Shoe is the superior choice for most applications. The packer shoe is made up on the bottom of the liner string and can be circulated on bottom. A flapper type float insert or float collar is used. A setting ball is dropped and pumped to the piston ball seat. An increase in ball pressure will shear the piston and set the packer element with downward force, expanding the element to seal against the casing. An increase of pressure will shear the piston from the packer setting ring, sending it to the bottom of the shoe, and exposing the cementing ports. The packer sleeve remains energized with an internal lock ring. Circulation can resume up the annulus followed by the cement operation. All internal parts of the shoe are drillable.

41 CEMENTED/SLOTTED LINER ASSEMBLIES TIEBACK TBR SEAL NIPPLE AND ORIFICE FLOAT COLLAR The Chancellor Tieback Receptacle (TBR) is usually run as an integral part of the Liner Top Packer or Setting Collar and at liner top. It has a special surface fi nish so as to provide a positive sealing bore for the seal nipple assembly during tubing string expansion and/ or contraction in response to pressure to pressure and temperature. The Polish Bore Receptacle provides the maximum internal opening through the production tubing and sealing system. The Chancellor TBR Seal Nipple is the second part of the Tieback System and provides a unitized seal assembly on a stem which connects to the end of a tubing or casing string and to successfully create a packer less, free-end tubing to casing seal. When used in uncemented or frac applications, the seal integrity is maintained allowing tubing to expand and contact in response to pressure and temperature differences without affecting the integrity of the tubing to casing seal. Typically a series V-ring (or Chevron) seal stacks are assembled on the seal nipple mandrel and separated by spacer rings. The orientation of the rings can be alternating to seal from both directions, or unidirectional to seal from only one direction. To prevent leakage, the unitized seal assembly mandrel has no threaded connections between seal units. The number of sealing rings per set and the material composition can be changed to match the well conditions or applications. The Seal Nipple consists of a locating collar on top which connects to the bottom of the tieback string. A mule Shoe is directly below the Seal Stem section to assist in the TBR entry. A guide ring keeps the seals from contact damage with the casing and especially important in highly deviated or horizontal wells. The guide ring is held in place with a Colette that collapses when in contact with the top of the TBR and allows the seal stem to enter TBR with seals intact and undamaged. For cemented Tieback applications, the TBR Seal Nipple is combined with a stage collar or ported put and an Orifi ce float collar. The Orifi ce Float Collar is designed with small diameter drilled holes through the float valve to allow fluid bypass and preventing hydraulic lock as the Seal Nipple stabs into the TBR after cement is in place. A Polish Mill is run before to clean out TBR. 40 TIEBACK TBR SEAL NIPPLE ORIFICE FLOAT COLLAR

42 CEMENTED LINER ASSEMBLIES STAB-IN EQUIPMENT Stab-In cementing provides better volume and pressure control leading to improved cementing jobs by allowing the operator to pump the cement slurry through the drill pipe. This technique is especially effective when collapse must be offset in large diameter, thin-wall casing, since no packer cups are used the effects of upward hydraulic forces are eliminated. When there is a large displacement problem, or when close control of returns is necessary through large-diameter casing, inner-string operations offer major benefi ts. Chances of cement contamination are decreased, and densities can be easily maintained. And the weight of the landed casing string is less when cementing through the drill pipe. Chancellor equipment is available for inner-string cementing in all sizes and connections. The float shoe can be supplied with down jet ports that give an even distribution of fluid around the circumference of the shoe joint. SETTING TOOL THREADED INTO CEMENTING SHOE ASSEMBLY.

43 CEMENTED LINER ASSEMBLIES BH PBR AND BH SEAL NIPPLE The Chancellor Type BH Polish Bore Receptacle (PBR) is usually run as an integral part of the liner string directly below the liner hanger or setting collar. It is specially bored and honed so as to provide a positive sealing bore for the seal nipple assembly during tubing string expansion and/or contraction in response to pressure to pressure and temperature. The Polish Bore Receptacle provides the maximum internal opening through the production tubing and sealing system and will not restrict the I.D. The Chancellor Type BH Seal Nipple is the second part of a Polish Bore Receptacle and provides a unitized seal assembly on a stem which connects to the end of a tubing or casing string and to successfully create a packer less, free-end tubing to casing seal. The seal integrity is maintained allowing tubing to expand and contact in response to pressure and temperature differences without affecting the integrity of the tubing to casing seal. The BH Seal Nipple can be optioned with a snap latch to anchor into the setting collar or liner top packer running threads. The Seal Nipple can be released with RH rotation. Typically a series V-ring (or Chevron) seal stacks are assembled on the seal nipple mandrel and separated by spacer rings. The orientation of the rings can be alternating to seal from both directions, or unidirectional to seal from only one direction. To prevent leakage, the unitized seal assembly mandrel has no threaded connections between seal units. The number of sealing rings per set and the material composition can be changed to match the well conditions or applications. A mule shoe entry guide allows for easy installation into the PBR.

45 CEMENTED LINER ASSEMBLIES MODEL HO HYDRAULIC STAGE COLLAR The Chancellor Model HO Hydraulic Stage Collar is a tool designed to provide a means of opening and closing a port int he liner string for the purpose of cementing up a liner string. The HO cement ports are hydraulically opened with the application of pressure and mechanically closed using cementing plugs and pressure. It is most often used when cementing combination cemented/slotted liners. The HO allows the effective delivery of cement to the upper section of the liner string with pressure tight integrity afterward. The Stage Collar is typically combined with an ECP to seal off the annulus and a baffle plate, ball seat or reverse flapper valve to retain the cement within the liner. These are critical items for keeping the cement above the slotted liner and out of the uncemented formation below. This Hydraulic Stage Collar system can be run with hydraulic or mechanical liner hangers and liner top packers above. The hydraulic opening feature eliminates the need to drop an opening plug which would be diffi cult or impossible to do with a standard liner hanger system in the hole on drill pipe. The Model HO Stage Collar is designed to hydraulically opens with differential pressure, however, there are a couple of features that make the HO stand out above the cementing stage collars on the market that were designed for primary cementing operations. It is imperative to get the closing sleeve shut and sealed with a stage collar used in a cemented liner assembly. The HO incorporates a much more effect body lock system to prevent the sleeve from moving up after closing in the bottom closed position or anywhere along the path of travel even if it does not close all the way. The closing Liner Wiper Plug also features a latch in and seal to provide a back up in the event the sleeve does not close. With liner on bottom, the setting ball is dropped to land at the ball seat just below the ECP. Pump pressure is increased to set the hydraulic hanger (typically psi, open and inflate the ECP (approx psi) and lastly to hydraulically open the Stage Collar (approx psi) to allow for circulating and cement operation to follow. The drill pipe dart is launched to displace the drill pipe and latch in at the Liner Wiper Plug. Displacement of liner continues with the tandem plugs landing and latching at the HO Stage Collar psi over pump pressure is suffi cient to shear out and lock the closing sleeve. All internal parts are aluminum alloy and easily drilled, and are fi rmly held from rotating during drilling. The port closing sleeve is positively locked in position after cementing. There are no internal restrictions after drill out. 44 MODEL JM SOLID NOSE CLOSING PLUG MODEL HO HYDRAULIC STAGE COLLAR

47 CASING PATCH HOOK SKIRT WITH INTERNAL SLIPS AND SEAL The Chancellor Hook Skirt is a very effective and economical tool for making a mechanical connection to a liner top or cut off stub in cased hole or open hole. The casing can then be extended up the hole or to surface and cemented to make a permanent pack off that becomes part of the casing or tubing string. The Hook Skirt has a cut lip on the bottom that ensures the successful capture of the stub with right hand rotation. The Hook Skirt is lowered over the stub until it takes weight. The internal slips engage the stub when picked up. The slips are hardened to RC 58 min to provide a positive and secure grip on the hardest casings. The slips are pull rated for up to 100,000 lbs tension. There are two choices for internal seal. The O-Ring seals are suffi cient where seal integrity is not that critical and economy is more of a consideration. The Packer Element type is the better choice for providing a more positive seal and allows room for irregularities in the casing stub. The internal packer element is energized with the over pull. 10,000 lbs pull is suffi cient to set the packer. ELEMENT TYPE WITH WICKER BODY LOCK 46 O-RING TYPE

48 SETTING TOOLS SLOTTED LINER SETTING TOOLS The Chancellor Slotted Liner Setting Tools are designed for running and setting uncemented (slotted or blank) liners with Chancellor Hydraulic Set Liner Hangers with a Liner Top Packer. A floating nut on a two sided Kelly is provided on all slotted liner setting tools. A lifter and junk screen is standard when running a Liner Top Tie Back Receptacle (TBR). After setting the hanger, or setting the liner on bottom, the setting tool is put in the neutral position and rotated right to release the running nut from the setting collar. The tool is then picked up and pulled out of the hole. A tubing swivel is included when running a tubing tail in slotted liner to eliminate tubing rotation during release. The Slotted Liner Setting Tools are pressure tested before each run. A packer setting dog sub (PSDS) is used to set liner top packers after displacing cement. The PSDS consists of spring loaded dog segments that collapse and reside in the TBR while running the liner in the hole. In this run position there is virtually no way to accidentally set the packer. After setting the hanger, and releasing, the setting tool is picked up so that the PSDS clears the top of the TBR. The dog segments are now expanded and can be used to apply weight to set the liner top packer. A Rotating Packer Dog Sub (RPDS) has a journal bearing that allows the packer weight to be rotated in. This is especially benefi cial in highly deviated or horizontal applications. A 40,000 lb shear indicator is provided to verify that weight was applied to the packer. The Type BSL Setting Tool features a 2S ball seat located between a PCPA double opposing cup mandrel and a TBR Packoff. The 2S set port is covered by a port piston during run in to prevent inadvertent hanger setting due to high circulating pressures or surges. The setting ball lands on the piston to shear out at approximately 1000psi to expose the hanger set ports. The ball seat piston shears out at 2500 psi to allow for full fluid bypass to circulate a change over after set and prevents hydraulic lock when pulling out of the Packer. There is no rotating allowed while running in the hole with the BSL. The Type BSL setting tool is pressure tested before each run. The Type ESL Setting Tool features a setting port located between a PCPA double opposing cup mandrel and a retrievable packoff bushing (RPB) in combination with a slick joint. The 2S ball seat is also an option for setting the hanger. The Type ESL Setting Tool also provides a spring loaded rotating dog sub that mates with splines located in the setting collar. This dog sub transfers torque from the drill string, to the liner, while in tension or compression for the purpose of setting mechanical hangers, rotating liners during the cement operation, or insuring setting tool engagement during run-in.

49 SETTING TOOLS CEMENTED LINER SETTING TOOLS The Chancellor Cementing Setting Tools are designed for running, setting and cementing liners with Chancellor Mechanical or Hydraulic Set Liner Hangers with or without Setting Collars or Liner Top Packers. The Type A Setting Tool provides a floating nut on a two sided kelly. A lifter and junk screen is standard when running a Liner Top Tie Back Receptacle (TBR). After setting the hanger, or setting the liner on bottom, the setting tool is put in the neutral position and rotated right to release the running nut from the setting collar. The tool is then picked up and pulled out of the hole. A type B slick joint is used in combination with the drillable pack off bushing (DPB) to produce a seal between the liner and the setting tool during cement operations. The Type B Setting Tool has all the capabilities of the Model A and also provides a Rotating Packer Setting Dog Sub (RPSDS) and is used to set liner top packers after displacing cement. The PSDS consists of spring loaded dog segments that collapse and reside in the TBR while running the liner in the hole. In this run position there is virtually no way to accidentally set the packer. After setting the hanger, cementing the liner, and releasing, the setting tool is picked up so that the PSDS clears the top of the TBR. The dog segments are now expanded and can be used to apply weight to set the liner top packer. A bearing is included so that the weight can be rotating in. This is especially benefi cial where the liner top is highly deviated or horizontal liner and getting the set weight in is diffi cult. There is a 40,000 lbs shear indicator that is most often felt at surface for confi rming that suffi cient set packer weight was applied. In addition to the Model B, the Model BR provides a Rotating Dog Sub (RDS) that mates with splines located in the setting collar. This dog sub transfers torque from the drill string, to the liner, while in tension or compression for the purpose of setting mechanical hangers, rotating liners during the cement operation, or insuring setting tool engagement during run-in. In addition to the above, the Model D also utilizes the Retrievable Pack off Bushing (RPB) and slick joint. The RPB system is mot preferred method of sealing the liner during cementing as it eliminates the upward hydraulic forces during pumping and eliminates the need for cement drill out. The The Model E setting tool has all the features of the Model D including the PSDS. The EHR hydraulic setting tool has the RPDS as well as the RPB but is features complete hydraulic liner hanger setting and hydraulic straight pull release where mechanical release is sometimes diffi cult or impossible as well as a secondary mechanical release back up option. The liner can be circulated and rotated in tension, compression, and neutral while running in the hole. This is most benefi cial in horizontal applications. TYPE A TYPE BR TYPE D TYPE E TYPE EHR 48

50 SETTING TOOLS PACK OFF SEAL SYSTEMS The Chancellor Drillable Pack Off Bushing (DPB) is used to provide a seal between the liner and setting tool during cementing operations. A Type B slick joint is stabbed into the V-ring Seal Pack Off Assembly to provide a high integrity seal. This method signifi cantly reduces the upward hydraulic force on the drill pipe during cementing when compared to the casing packer cup method to provide seal. This is especially benefi cial when cementing larger diameter liners, and/ or cementing at relatively shallow depths where this upward force might exceed the drill pipe string weight and hydraulic up the hole and possibly losing the seal between the liner and the setting tool and ruining the cement job. The DPB is an integral part of the liner string and remains in the hole when the setting tool and slick joint are removed T6511 aluminum alloy is used internally for easy drillability. The Chancellor Retrievable Pack Off Busing (RPB) combines the benefi ts of the Drillable Pack Off Bushing with retrievability. The RPB is made up on the setting tool with the slick joint extended through it. The RPB is then landed and locked into the machined profi le of the setting collar (or packer). After the cementing operation, the RPB is released and retrieved with the setting tools. No material or seals are left to be drilled out later. The Chancellor Packer Cup Pack Off Assembly (PCPA) provides a superior and most economical and simple internal seal system when the superior sealing properties of a slick joint and cement bushing are not required. The dual inverted packer cups are installed on a mandrel just below the setting tool. After the cement job the packer cup assembly is retrieved from the liner. The PCPA is not recommended for use in medium to deep wells, or with use on large diameter liners or high temperature applications. 49 PCPA DPB RPB

51 SETTING TOOLS CLEAN OUT MILL Before a liner top tie back packer or seal nipple is run, it is sometimes necessary to run a polish mill down through the tie back receptacle (TBR) or seal bore to eliminate any burrs or cement stringers and/or deposits. This will insure a high integrity tie back seal. The TBR polish mill has longitudinal mill cutters for cleaning out the TBR and a top locating collar with fi ne grain carbide for dressing the chamfered TBR entry. TOP LOCATING COLLAR FINE GRAIN CARBIDE MATRIX It is possible to run a tandem polish mill designed to clean out the liner top TBR as well as a below hanger (BH) polish bore receptacle (PBR) in one trip. This two stage mill consists of a top polish mill as previously described to clean out the top TBR and a bottom mill separated from the top mill by a spacing collar to clean out the bottom PBR. A pilot bit can be run below the bottom mill if required. EXTENSION MANDREL SECTION THRU MILL LONGITUDINAL FLUTED MILL 50

The 325R Manifold has a load rating of 500,000 lbs. static and 325,000 lbs. dynamic. The 325R Manifold is a fast acting cement head that provides a convenient method of maintaining mud/cement separation following the cement pumping operation. The single two way valve is the key to its rapid and effi cient plug initiation. Operation is very simple and foolproof. The plug is installed into the receptacle located in the top portion of the cement head. The line on the valve must be 900 to the drill pipe. Next, the actuating lever is installed in the valve locking hole, thereby preventing any chance of accidental valve movement. The drill pipe wiper plug resides in the upper part of the cement head while cement is pumped through the lower part via the two-way valve. Following the cement pumping operation, the valve is rotated 900 and the drilling mud or water is directed to the top of the cement head, Thee displacement fluid pressure forces the wiper plug through the cement head valve and into the drill pipe, maintaining displacing fluid/cement separation. The line on the face of the valve points in the direction of the plug movement. A stop mechanism precisely aligns the valve position. It is impossible to send the plug down the drill pipe until the valve positioning hole is provided allowing one to insert the actuating lever locking the valve in the open position. The Model TD Top Drive Cement Manifold is the preferred choice for use with rotating liner hangers and a top drive unit. The manifold s solid construction is rated for 1,300,000 lbs tensile strength. A double set of bearings and seals allow for easy rotation. The drill pipe dart is loaded in the plug sub. Cement is pumped down thru the swivel and is bypassed around the dart. The plug is launched and displaced by rotating the bypass plug valve 180 degrees closed and opening the plug ball valve 180 degrees open. A flag sub or a ball dropping sub can be used in conjunction with the TD manifold. 51

Running the Flag Sub is standard on all cemented liner jobs. The Flag Sub is easily maintained and serviceable. The Flag Sub can be run with both the Rotary type cement manifold and the Top Drive cement manifold. The central mechanical part of the Flag Sub is an actuator arm that is set in the center of the sub I.D. and extends perpendicular to the Flag Sub flow. This actuator arm is keyed to a sealed flag mandrel which protrudes form the Flag Sub body. An external lever arm is fi xed to the end of the mandrel. This external lever arm is held in place with a brass trip wire. This wire is suffi ciently strong to keep the internal actuator arm in the flow path during normal circulating and cement pumping. After launch, the drill pipe dart contacts and shears out the trip wire with negligible pressure. After shear the internal actuator arm swings completely out or the flow path, rotates the mandrel 90 degrees and provides the external indicator required. This external lever arm movement can be seen from a fair distance. A shroud is fastened to the Flag Sub to protect the external lever arm and retainer arm. The Ball Drop Sub is run directly below the Cement Manifold and Flag Sub. The purpose of the Ball Drop Sub is to provide a means of dropping a setting ball in the circulation flow without picking up and breaking a connection. This is especially necessary for setting of the hydraulic liner hanger. The design of the Chancellor Ball Drop Sub includes a ball valve housing that is separate from the main body and outside of the full flow path during circulating. No tensile load is carried through the ball valve. The setting ball is loaded in the valve housing prior to the job. With setting ball loaded, the rotating valve is pinned in the circulating position. This prevents the accidental launching of the setting ball. When ready to drop the ball, the retainer pin is pulled, a valve wrench is used to rotate the valve 90 degrees to the drop position. An external drop position indicator is provided. After drop the valve is pinned. 52
