2 1 Purpose of this Directive This directive consolidates various aspects of water anageent requireents for theral in situ oil sands operations. It sets water disposal liits and includes detailed requireents for reporting injection facility water streas to PETRINEX to ensure that Energy Resources Conservation Board (ERCB) facility water balance requireents are et. The disposal liits requires operators to recycle produced water efficiently and ensure that ake-up water is effectively used. Efficient water treatent, recycle, and disposal at theral operations will optiize overall water use and energy efficiency. In addition to liiting disposal, this directive provides forulas for water ake-up, water productivity ratios, and produced-water recycle that will be used for onitoring and coparing theral operations in Alberta. These forulas, along with schee voluetric data, will be published on the ERCB website. The ERCB will review the requireents of this directive regularly and ay revise requireents as a result of iproveents in water treatent, recycle, and stea generating technology; changes introduced by operators to field operations and water handling; changes in bituen recovery technology that ipact water treatent, recycle, and disposal; policy and regulatory changes introduced by other governent agencies; and alignent with other ERCB directives. The ERCB has also copiled and defined a list of ters used in this directive to provide clarity and to ake the inforation in the directive ore accessible (see Appendix A). 2 What s New in this Directive? This directive replaces Bulletin : Water Recycle, Reporting and Balancing Inforation for In Situ Theral Schees, and supersedes and replaces Inforational Letter (IL) 89-05: Water Recycle Guidelines and Water Use Inforation Reporting for In Situ Oil Sands Facilities in Alberta. The following table lists the requireents in this directive and the reason for their inclusion. 2 ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012)

3 Table 1. What s New in This Directive? Requireent This directive Prior to this directive Injection facility water balance Specifies a axiu onthly facility ibalance (see section 4.1). ERCB Directive 017: Measureent Requireents for Oil and Gas Operations does not set a axiu facility ibalance for water. Exeption fro water recycle Disposal liit forula Specifies requireents for conducting a onthly water balance on a theral in situ injection facility (see Appendix B). Sets a axiu disposal liit for all theral in situ oil sands schees where the total water ake-up exceeds cubic etres ( 3 ) annually in the absence of produced-water recycle (see section 5). Optiizes produced-water recycle by liiting disposal based on the quantity of fresh, brackish, and produced water used at the central processing facility (see section 5 and Appendix C). The ERCB ethodology, rules, and equations used in conducting a water balance on theral in situ injection facilities could be found in various docuents and were ade available in eetings with stakeholders. IL 89-5 required theral in situ schees to recycle produced water if fresh water deand exceeded annually and actively investigate and test recycle technology if deand was under annually. Most theral coercial schee approvals required a iniu annual produced-water recycle rate based on the forula in Bulletin The recycle forula did not account for ake-up water sources other than those that are fresh. 3 ERCB Requireents and Copliance Assurance Requireents in this directive are those rules that a theral in situ oil sands operator is required to follow. The ter ust indicates a requireent, while ters such as should and encourages indicate a recoended practice. Noncopliance with any risk-assessed requireent in this directive will result in the operator receiving a response in accordance with the latest edition of ERCB Directive 019: Copliance Assurance. Soe exaples of noncopliance for which the ERCB will take enforceent action are if actual water disposal at the schee exceeds the disposal liit, the onthly injection-facility water balance closure is greater than 5.0 per cent for three consecutive onths, or fresh water is reported as brackish water in PETRINEX. The ERCB encourages all in situ oil sands operators to be proactive by onitoring their copliance with this directive. If an operator identifies a noncopliance, it should infor the ERCB of the noncopliance for consideration under the ERCB Voluntary Self-Disclosure policy set out in Directive 019. For a list of noncopliant events and further details on copliance assurance, including Directive 019 see the ERCB website Copliance with Disposal Liit For the first twelve onths of schee start-up, the ERCB will not strictly enforce the disposal liit (see section 5). The start-up period is fro the coenceent of stea injection. Once this twelve-onth period is coplete, the ERCB will use the reaining ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012) 3

4 onths of that calendar year to calculate the disposal liit to deterine copliance for that year. The start-up grace period does not apply to schee expansions. The ERCB will consider variations of the disposal factors in Table 2 of section 5 upon application in cases where high produced-water rates or high concentration of total dissolved solids (TDS) in ake-up water ake it difficult to eet the disposal liit (e.g., water-tostea ratio exceeds 1.05 or TDS exceeds g/l). It is the operator s responsibility to justify any deviation fro the requireents in section 5. 4 Water Reporting and Facility Water Balance 4.1 Injection Facility Monthly Water Balance The ERCB equation for onthly water ibalance on an injection facility is provided in Table B3 of Appendix B. This onthly ibalance will correspond to the balancing activity DIFF for the product group WATER in the Suary view for an injection facility in PETRINEX. The onthly ibalance ust not exceed 5.0 per cent for three consecutive onths or ore. Accurate water easureent is needed in order to eet the injection facility onthly ibalance requireent and to reliably calculate the disposal liit (section 5.2) and actual disposal (section 5.3). Water easureent requireents for theral in situ oil sands operations are set out in sections 12.3 and 12.4 of Directive 017: Measureent Requireents for Oil and Gas Operations. 4.2 Reporting to PETRINEX Operators ust report onthly water streas to PETRINEX in accordance with the definitions and equations in Appendix B. The data are used by the ERCB to deterine copliance with the axiu injection facility ibalance of 5.0 per cent (see section 4.1) and with the annual schee disposal liit (see section 5 and Appendix C). The correct reporting of water is also necessary in order to onitor and evaluate the perforance of each schee. To help ensure that water volues are correctly reported to PETRINEX, exaples of the required PETRINEX reporting of water and the required water balance calculations have been included in the appendices of this directive and are described below. For each exaple, the stea volue is reported in cold water equivalent. 1) Appendix D provides a siplified water-flow diagra with PETRINEX reporting codes and required etering for a saple theral schee. The appendix also illustrates the boundary between a battery and injection facility for the purpose of reporting to PETRINEX (i.e., produced water leaving a battery requires no further hydrocarbon separation.) 2) The required reporting of the saple schee water volues fro Appendix D to the correct PETRINEX codes is provided in tabular for in Appendix E. 3) Appendix F displays the resulting PETRINEX screen shots for the saple schee facilities in Appendix D to illustrate what the Suary, Facility Activity, and Well Activity views of PETRINEX would look like for the reporting requireents in Appendix B. 4 ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012)

5 4) For the sae saple schee facilities, Appendix G shows how the correctly reported water volues fro PETRINEX are used to generate a onthly water balance, using the required equations fro Table B3, Appendix B. 5 Forulas and Liits for Disposal at Theral In Situ Schees This section establishes a axiu water disposal liit for each theral in situ operation in Alberta. The axiu disposal liit is intended to ensure efficient recycling of a schee s produced water and to proote energy efficiency. Effective iediately, the axiu water disposal liit applies to all new schees. For existing schees, the axiu water disposal liit will becoe effective either when the licensee applies to expand a schee s bituen processing or stea generation capacity (applied to the entire schee within the tie frae stated in the approval), or three years fro Noveber 21, 2012, unless a shorter period is applied for by the operator. The effective date of the axiu disposal liit will be whichever date occurs first. The liits set out in this section do not apply to theral in situ oil sands schees that, in the absence of produced-water recycle, have a total annual volue of ake-up water less than Overview Water disposal at a schee is affected by the quality and quantity of water streas entering the facilities in the schee, the treatent technologies being used, and the bituen recovery echanis. Based on available technologies and bituen recovery echaniss, the ERCB has established a disposal allowance for each type of water used at theral operations. These allowances are entered into the disposal liit forula to deterine the axiu disposal liit for the schee (see section 5.2). The axiu disposal liit will be enforced against the total annual (calendar year) volues of water disposal at each schee. Forulas ust be applied on a schee basis. Schees with ultiple injection and disposal facilities cannot apply these forulas to individual facilities. For the purpose of this directive, the water types used in the disposal-liit forula are fresh, brackish, and produced, with the recovery echaniss being stea-assisted gravity drainage (SAGD) and cyclic stea stiulation (CSS). If water types, recovery echaniss, or treatent technologies change, this directive and its liits will be aended accordingly. For disposal forulas using ERCB water balance codes, see Appendix C. ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012) 5

6 5.2 Disposal Liit Forula The axiu disposal liit for a schee is calculated as a percentage of the schee s total inlet water volue: Fresh In x D Brackish In x D Produced In x D + + f b p Disposal Liit (%) = 100 Fresh In + Brackish In + Produced In where Fresh In = the annual volue of inlet fresh water in 3 for the schee fro volues reported in PETRINEX. Brackish In = the annual volue of inlet brackish water in 3 for the schee fro volues reported in PETRINEX. Produced In = the annual volue of inlet produced water in 3 for the schee fro volues reported in PETRINEX. D f = the disposal factor for fresh water. D b = the disposal factor for brackish water. D p = the disposal factor for produced water. Table 2 provides the disposal factors for the recovery echanis used in the schee. Table 2. Disposal factor by theral in situ recovery echanis Disposal factor Inlet water type SAGD CSS Df Fresh water Db Brackish water Dp Produced water Actual Disposal Forula The actual disposal forula gives the total schee disposal as a percentage of the schee s total inlet water volue: Total Disposal Actual Disposal (%) = 100 Fresh In + Brackish In + Produced In where Total Disposal = the annual volue in 3 of schee water injected into designated disposal wells and annual volue of schee water delivered out of the schee. Fresh In = the annual volue of inlet fresh water in 3 for the schee fro volues reported in PETRINEX. Brackish In = the annual volue of inlet brackish water in 3 for the schee fro volues reported in PETRINEX. Produced In = the annual volue of inlet produced water in 3 for the schee fro volues reported in PETRINEX. The schee s actual disposal ust not exceed the liit calculated by the disposal liit forula. 6 ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012)

7 6 Data Publication Coincident with the release of this directive, a new interactive publication Theral In Situ (TIS) Water Publication of onthly and annual water usage at all coercial theral in situ schees is available on the ERCB website. The publication includes water disposal liits and actual water disposal (sections 5.2 and 5.3), and additional schee perforance indicators (Appendix H).

9 Appendix A Battery Boiler blowdown Definitions A syste or arrangeent of tanks or other surface equipent receiving the effluent of one or ore wells prior to delivery to arket or other disposition, and ay include equipent or devices for separating the effluents into oil, gas or water and for easureent. Boilers used in theral recovery processes typically produce stea with a quality between 75 and 80%. This results in 20 to 25% of the boiler feed water not being vapourized, and in stea-assisted gravity drainage (SAGD) schees, the resulting liquid is separated fro the stea. This separated water strea leaving the boiler is called blowdown and contains ore concentrated total dissolved solids, typically 4 to 5 ties ore, than the boiler feed water. Brackish water (saline groundwater) Cap Cold water equivalent (CWE) Existing schee Fresh water (nonsaline groundwater or surface water) Injection facility For the purpose of this directive and for reporting to PETRINEX, brackish water is saline groundwater defined in Part 1(1)(z) of the Alberta Water (Ministerial) Regulation as water that has total dissolved solids exceeding 4000 illigras per litre. Such groundwater is defined as brackish water in PETRINEX and saline groundwater by Alberta Environent and Sustainable Resource Developent. For the purpose of this directive, a cap is a residential housing facility for construction and operations workers associated with a theral injection schee. All produced and injected water and stea volue easureents are corrected to a standard teperature of 15 o C and kilopascals absolute and reported in 3. A schee that has received ERCB approval before the issuance of this directive, even if not yet constructed. For the purpose of this directive and for reporting to PETRINEX, fresh water is either nonsaline groundwater, which is groundwater that has total dissolved solids less than or equal to 4000 illigras per litre, or surface water, which is as defined in Part 1(1)(bb) of the Alberta Water (Ministerial) Regulation as all water on the ground surface, whether in liquid or solid state. A freshwater source ay refer to a well licensed by the ERCB drilled to a depth of greater than 150 ; a shallow well with a depth of less than 150 ; a surface water source, such as a diversion point at a lake or a river (regardless of TDS); or surface runoff collected. Regardless of the source, all freshwater use requires a diversion licence fro ESRD in accordance with the Water Act. A syste or arrangeent of surface equipent associated with the injection or disposal of any substance through one or ore wells.

10 Make-up water New schee PETRINEX Produced water Schee Stea Water balance Water used at theral in situ operations other than produced water fro wells within the schee. This water ust ake up for water losses such as the disposal of water treatent waste streas, boiler blowdown, and reservoir retention of injected stea. A schee that did not receive ERCB approval before the directive was issued. PETRINEX is a web-based syste that provides anageent/exchange of voluetric, royalty, and coercial inforation associated with the upstrea petroleu sector for the Provinces of Alberta and Saskatchewan. Water that is produced in association with hydrocarbon production fro a well that was licensed for the purpose of hydrocarbon production. For the purpose of this directive, a schee includes all batteries and injection facilities associated with an ERCB theral in situ oil sands schee approval. For reporting to PETRINEX, the su of all stea injection of varying quality, reported in cold water equivalent. A series of calculations the ERCB uses on water volue data that are reported to PETRINEX to give the ERCB an indication of easureent and reporting accuracy for a facility. The water balance identifies all water types and water uses, and deterines the ibalance between the total input and total output streas. 10 ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012)

24 Appendix H Additional Schee Perforance Indicators using ERCB Water Balance Codes The ERCB uses the following forulas to assess schee perforance and to copare schees. If ultiple injection or disposal facilities exist within a schee, values for all facilities ust be sued. (e.g., BW1 = BW1 for all injection facilities). 1) Freshwater Productivity Ratio (FW1+ FW4 - FW5) Bituen Production 2) Brackish-Water Productivity Ratio (BW1+ BW4- BW5) Bituen Production 3) Disposal Ratio DIT Bituen Production 4) Freshwater Make-up (%) (FW1+ FW4 - FW5) (INT + DIT) 100 5) Brackish-Water Make-up (%) (BW1+ BW4 - BW5) (INT + DIT) 100 6) Produced-Water Recycle (%) [(PW1+ PW4 - PW5 - PW8) - DIT] (PW1+ PW4 - PW5 - PW8) 100 The above forula for produced-water recycle assues that all disposal (DIT) is fro the produced-water streas. Since ake-up water in the disposal strea is expected to be sall and is usually not possible to track, this forula is a good approxiation of the iniu produced-water recycle. 24 ERCB Directive 081: Water Disposal Liits and Reporting Requireents for Theral In Situ Oil Sands Schees (Noveber 2012)
