Coiled Tubing for Downhole Applications

Coiled Tubing for Downhole Applications

Tenaris Tubular technologies. Innovative services. Tenaris is the leading global manufacturer and supplier of tubular products and services used in the drilling, completion and production of oil and gas and a leading supplier of tubular products and services used in process and power plants and in specialized industrial and automotive applications. Through our integrated global network of manufacturing, R&D and service facilities, we are working with our customers to meet their needs for the timely supply of high performance products in increasingly complex operating environments. Coiled Tubing for Downhole Applications Tenaris is the leading manufacturer of coiled tubing products worldwide. At our two plants in Houston we have been producing the finest grades of downhole tubing for the oil and gas industry since 1991. We offer a range of downhole products tailored to the specific demands of an expanding spectrum of downhole coiled tubing applications. From standard well workover and velocity / production strings to logging, drilling and special application strings with factory installed wireline, capillary tubes, or integral tools, Tenaris designs and builds the tubing string best suited to ensure the success of the project. Quality Today s oil and gas industry requires coiled tubing that meets the most complete quality standards. In addition to our Quality Assurance System (which includes ISO- 9001 certification), Tenaris also ensures the supply of the highest quality coiled tubing products through the industry s first API 5ST certification.

Slit master coils are ready for assembly. Applications The use of coiled tubing for oil and gas well service operations has increased significantly over the past 10 years. Tenaris provides coiled tubing for a variety of applications, including: Drilling: Coiled tubing has achieved great success performing reentry drilling, where a horizontal lateral is drilled in an existing well with a coiled tubing conveyed mud motor and bit. Coiled tubing reentry drilling can be performed through the existing production tubing and in an under balanced condition. Drilling new wells from the surface with larger 3-1/2 and 4-1/2 coiled tubing has been successful in certain markets, especially shallow gas wells in Canada. Logging/Perforating: Wireline cables installed inside coiled tubing allows the deployment of logging or perforating tools in highly deviated wells. Coiled tubing offers several advantages over traditional wireline methods, including enduring greater tensile and compressive forces and the ability to work in live wells. Fracturing: Coiled tubing has advantages over traditional methods when fracturing relatively shallow wells multiple zone completions. Coiled tubing can convey zonal isolation tools to pinpoint the fracture treatment and then the coiled tubing is used as the conduit for the fracturing fluid. The fracturing process can be repeated multiple times on a single coiled tubing run. Milling Frac Plugs: The large multistage fracture treatments that are common in horizontal shale gas completions require setting multiple frac plugs for zonal isolation. Coiled tubing, in conjunction with mud motor and bit assembly is then used to mill out the frac plugs and clean the wellbore. Cleanouts: Coiled tubing can be used to remove scale, produced sand, frac sand and debris from the wellbore. Coiled tubing is run into the wellbore, fluid is pumped down the coiled tubing and returns are circulated through the annulus. Coiled tubing can rig up and get to depth quickly without killing the well or pull the production tubing. Nitrogen Injection: Coiled tubing allows the injection of nitrogen at depth into a dead wellbore to displace the wellbore fluid with nitrogen. This lowers the bottom hole pressure and allows the well to resume flowing. Stimulation: Coiled tubing matrix stimulation treatments are designed to restore the natural permeability of the near-wellbore formation by injecting treatment fluids into the formation. Coiled tubing stimulation can be performed on live wells and combined with other operations such as nitrogen injection. Velocity Strings: Coiled tubing is run into an existing producing well to reduce the effective flow area to allow the natural reservoir pressure to lift water from the reservoir, allowing natural pressure to sustain production in mature producing wells. Electrical Submersible Pump (ESP) Installation: An ESP cable can be installed into the coiled tubing prior to deployment, enabling the coiled tubing to support the ESP cable, and facilitate the rapid deployment and retrieval of ESPs.

Setting Industry Standards Tenaris has been setting industry records since it began producing coiled tubing. Tenaris is the first API 5ST certified coiled tubing manufacturer, leading the standardization of the industry. Tenaris has a history of industry milestones, including one of the longest coiled tubing workstrings, stretching to 36,430 ft of 2" HS-80, as well as one of the heaviest coiled tubing workstrings, weighing 122,000 lbs of 2-7/8" HS-80. The coiled tubing produced by Tenaris is high frequency induction welded while stainless steel products are laser welded to ensure maximum precision and durability. Always under API 5ST product control, coiled tubing can be manufactured in a variety of grades and cleanliness levels with pressure ratings up to 15,000 psi. The base tube of HFI welded product is made from carbon steel in continuous coils. The tube is then heat-treated, spooled, hydrotested and prepared for shipping. Tenaris s HS-80 CRA is a laser welded product made from lean duplex stainless steel.
