(BPX) for disposal of Class II oil field wastes by underground injection in the Badami Unit wells WD-1 and WD-2. ) Disposal Injection Order No. 12 ) ) ) ) ) Badami Unit Wells WD-1, WD-2 Badami Unit August 5, 1997 IT APPEARING THAT: 1. By correspondence dated May 22, 1997, BPX requested authorization from the Alaska Oil and Gas Conservation Commission (AOGCC) to inject Class II waste fluids into the Badami Unit WD-1 and WD-2 wells. 2. The AOGCC requested additional information June 11, 1997. BPX provided the requested information on June 18, 1997. 3. Notice of opportunity for public hearing was published in the Anchorage Daily News on May 30, 1997. 4. The Commission did not receive a protest or a request for a public hearing. FINDINGS: 1. BPX is the operator of the Badami Unit. There are no other operators within a one- quarter mile radius of the proposed disposal injection project. 2. The State of Alaska is the only surface owner within the Badami Unit. 3. The Badami Unit WD-l disposal well, (WD-l) will be the first well drilled from the unit's single development pad. BPX does not propose to drill any other well within a one-quarter mile radius of the WD-.l"penetration of the disposal injection zones. 4. BPX may drill an additional disposa!'well designated WD-2. BPX does not propose to drill any other well within a one-quarter mile radius of the WD-2 penetration of the disposal injection confining zones. SCANNED JUN 3 0 200~· Disposal Injection Order N' August 5, 1997 J ) Page 2 5. Logs from the Badami No.4 exploratory well may be used to define the disposal and confining zones in the Badami Unit. 6. BPX proposes to conduct disposal operations in the Badami Unit within the U gnu and Sagavanirktok Formations. 7. The Ugnu Formation consists of Eocene aged, predominately coarse grained, fluvial and shallow marine sediments. The interval is present within the Badami No.4 well from 7440'-7720' measured depth (MD). It has an average porosity of 27%, an average permeability of 350 millidarcies and an average net to gross ratio of 50%. 8. The Sagavanirktok Formation includes a basal unit which consists of Eocene to Oligocene aged, predominately fine grained marine sediments. The interval is present within the Badami No.4 well from 5526'-7440'-MD. 9. A regionally extensive, dominantly shale interval within the basal Sagavanirktok Formation is present within the Badami No.4 well from 5526'-5926' MD. This interval contains an aggregate thickness of shale in excess of 250'. 10. The basal Sagavanirktok Formation also contains numerous intervals of laterally extensive sandstones. The log character of these sands is similar to those which have demonstrated a large capacity to accept disposal fluids in other North Slope Fields. 11. Most of the Class II disposal fluids from other North Slope Fields has been confined by similar lithologic and stratigraphic intervals as those present within the U gnu and basal Sagavanirktok Formations underlying the Badami Unit. 12. Overlying the basal Sagavanirktok Formation, between 4450'-5526' MD interval in the Badami No.4 well, is an interval of approximately 65 percent highly porous and permeable, laterally continuous, fluvial to shallow marine sandstones. 13. A predominately mudstone interval exists between 3892'-4450' MD within the Badami No.4 well. It is considered the shallowest potential confining zone in the well. The gross lithologic character of this interval is persistent through the proposed WD-1 and WD-2 vicinity. 14. The 3892'-5526' MD interval in the Badami No.4 is designated the middle member of the Sagavanirktok Formation for the purposes of this order. 15. BPX does not plan to inject fluids within the middle member of the Sagavanirktok Formation unless injection in the Ugnu -basal Sagavanirktok Formation interval is unsuccessful. 16. BPX will run cement quality logs within the surface casing and long string of each well. The Commission will evaluate the logs and cement records to determine the adequacy of the cement to isolate disposal intervals. 5Ci\N~]ED JUN iJ 0 20D·¡~ Disposal Injection Order N,. ) August 5, 1997 ) Page 3 17. Completion plans entai120" conductor set at 110' subsea (SS), 13 3/8" surface casing set at +/-4230' SS and cemented to surface and a long string of 9 5/8" casing set at +/-7500' SS and cemented back into the surface casing. 18. BPX will test tubing and casing integrity according to 20 AAC 25.412 prior to initiation of disposal operations and every two years thereafter. 19. Disposal material will consist of Class II fluids generated from drilling, production, workover and completion operations. The typical disposal stream will consist of seawater, produced and fresh water, drilling mud, drill cuttings, workover fluids, stimulation materials, vessel cleaning material, formation sand, cement and other nominal Class II waste. Constituent volumes will vary depending on drilling, workover, stimulation and maintenance activity. 20. BPX expects to dispose of approximately 12,500 cubic yards (60,100 barrels) of solids during the life of the project. 21. Average disposal rate will be nominally 3000 BPD (,....,2 BPM) during development drilling and at other peak periods. The operator expects to average 300 to 500 BPD over the project life. Maximum instantaneous disposal rate is anticipated to be about 5 BPM. 22. Maximum operating pressure will vary depending on depth and the condition of the formation. Surface pressure is expected to range from 1800-3300 psi when disposing in the Ugnu-basal Sagavanirktok interval, with a corresponding bottom hole pressure (BHP) of 4950-6450 psi. In the mid-Sagavanirktok disposal intervals, estimated surface pressures will be 1300-2800 psi and estimated BHP 3500-4900 psI. 23. BPX expects to maintain injectivity by occasionally stimulating the disposal interval. Stimulation activity will entail pumping solid free fluid to disperse solids, chemical treatments and elevating pressure to breakdown the disposal interval. 24. Fracture propagation within the disposal interval is an integral part of the process of placing waste fluids into the disposal interval. Fractures will be created as the disposal zone begins to plug. Fractures or disaggregation of the clogged pores and rock matrix provide pathways to transport waste fluids to undamaged storage volume within the disposal zone. 25. Estimates of likely vertical growth of fractures in the upper disposal interval is approximately 250', based on rate and volume estimates. 26. Periodic surveillance of disposal operations will ensure waste fluids are contained within the disposal interval. Surveillance methods include temperature surveys, pressure transient tests, step rate tests, thermal decay time logs, disposal rate and pressure monitoring, mechanical integrity tests and tagging effective depth to determine fill buildup. 5CANNED JUN ~i {) 20D4 Disposal Injection Order Nl 2 August 5, 1997 ) Page 4 27. Reservoir surveillance techniques will also be used for tracking near wellbore fluid movement, estimating dimensions of disposal fracture or disposal storage volume and detecting changes in disposal zone characteristics. 28. Evaluation of operation performance and reservoir surveillance will aid in preventing fracturing of the confining zones. 29. BPX calculated formation fluid dissolved solid content from existing well control within the Badami Unit through analysis of geophysical logs calibrated to a single water sample from 4982' MD in the Badami No.5 well. Calculated salinity of formation waters ranged from 18,000 mg/liter to 48,000 mg/liter for formations between 2000' and 7,200' SS. 30. The U.S. Environmental Protection Agency (EP A) determined aquifers with total dissolved solids of less than 10,000 mg/liter are not present within the Badami Unit in either the U gnu or the Sagavanirktok Formations. 31. In correspondence dated May 12, 1997, the EP A notified BPX of its determination that no underground sources of drinking water (USDWs) were present in the Badami Unit. CONCLUSIONS: 1. The requirements of 20 AAC 25.252 have been met. 2. There are no USDW s present underlying the Badami Unit. 3. Waste fluids authorized for disposal under this order in the Badami Unit will consist exclusively of Class II waste generated from drilling, completion, workover and production operations. 4. Permeable strata which reasonably can be expected to contain the total volume of disposal fluids anticipated for this project are present in the Ugnu - basal Sagavanirktok Formation in the Badami Unit. 5. Movement of waste fluids will be confined within appropriate receiving intervals by confining lithology, cement isolation of the wellbore and operating conditions. 6. Periodic fracturing and stimulation will be required to place solids into the disposal interval. Fracture growth can be contained within the disposal interval by controlling the rate and volume of injection 7. Surveillance of disposal material movement, monitoring of operating parameters and demonstration of mechanical integrity every two years will ensure the materials are contained within the disposal interval. Changes in baseline data may be an indication that fluid is escaping beyond the designated confining zone. SCANhW¡i::~ì) JUN C). ,. vb,.(.

In the event disposal injection within the Ugnu - basal Sagavanirktok Formation interval is unsuccessful, alternative receiving and confining zones exist within the middle member of the Sagavanirktok Formation, which may serve as a secondary disposal zone. 9. Badami Unit disposal wells will be constructed and demonstrate mechanical integrity in accordance with the requirements of20 AAC 25.412. 10. Disposal injection operations in the Badami Unit will not cause waste, jeopardize correlative rights, or impair ultimate recovery. NOW, THEREFORE, IT IS ORDERED THAT: Rule 1 Authorized Injection Strata for Disposal. Class II oil field fluids may be injected in the Badami Unit WD-1 and WD-2 wells, in conformance with Alaska Administrative Code Title 20, Chapter 25, for the purpose of disposal into strata which correlates with the U gnu - basal Sagavanirktok Formation intervals between 5926'-7720' MD and the mid-Sagavanirktok Formation between 4450'- 5526' MD in the Badami #4 well. Disposal injection within the mid-Sagavanirktok F ormation must be specifically approved by the Commission, and may be further conditioned by administrative action after review of injection performance in the U gnu- basal Sagavanirktok Formation. Rule 2 Demonstration of Tubing/Casing Annulus Mechanical Integrity The tubing/casing annulus must be tested every two years for mechanical integrity in accordance with 20 AAC 25.412. Rule 3 Well Integrity Failure Whenever disposal rates and/or operating pressure observations or pressure tests indicate pressure communication or leakage of any casing, tubing or packer, the operator must notify the Commission on the first working day following the observation, obtain Commission approval of a plan for corrective action and obtain Commission approval to continue inj ection. Rule 4 Surveillance A baseline temperature survey from surface to total depth, initial step rate test to pressures equal or exceeding maximum injection pressure and pressure falloff are required prior to initiation of disposal injection. Regular fill depth tags are required at least once annually or as warranted following consultation with the Commission. Operating parameters including disposal rate, disposal pressure, annuli pressures and volume of solids pumped must be monitored and reported according to requirements of 20 AAC 25.432.

Rule 5 Administrative Action Upon request, the Commission may administratively revise and reissue this order upon proper showing that any changes are based on sound engineering practices and will not allow waste fluids to escape from the disposal zone. DONE at Anchorage, Alaska and dated August 5,1997. ~- -........... Robert N. Christenson, P.E., Commissioner AS 31.05.080 provides that within 20 days after receipt of written notice of the entry of an order, a person affected by it may tile with the Commission an application for rehearing. A request for rehearing must be received by 4:30 PM on the 23rd day following the date of the order, or next working day if a holiday or weekend, to be timely filed. The Commission shall grant or refuse the application in whole or in part within 10 days. The Commission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon rehearing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for rehearing is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., 10th day after the application for rehearing was filed). ~~(,ìiN~JE-~> ì·· '. -,- <,JLJN 3 () 200<1 \"IT ¡,Ç . .1 u1 } ffiì [~®;1 ® ~ ryl® ~ J wL~cQ)"J~W AI/ASIiA OIL AlVD GAS CONSERVATION COMMISSION ') / / / FRANK H.

Results were presented in the Badami B1-01 - 2014 Annual Surveillance Interpretive Report that was submitted to the EPA and AOGCC on 21 May 2014. In summary: 1. A successful MIT x IA test to 3,500 psi demonstrated mechanical integrity of the casing; tubing and packer run on 4 April 2014. 2. A Multi -finger caliper (MFC) run on 4 April 2014 showed the 2Y8' Velocity String from 8383 ft. MD to its top at 8474' MD and 4%2" tubing from 8075' MD to surface are in good condition. (mostly showing less than 20% penetration damage characterized by light to moderate pitting). Results showed the tubing to be generally 3. in a condition similar to that described by the MFC run in 2012, with most joints exhibiting less than 20% penetration damage or metal loss with that damage largely dominated by light to moderate pitting. 4. A Spectra Flow tool run on 5 April 2014 to check water flow behind the 9 5/8" casing showed no indication of water movement using impulse tests at 8340, 8325, 8300 and 8275 ft. MD, while injecting the well with water at a rate of 2 BPM.. 5. Fill was tagged at 8,391 feet measured depth below gravel pad surface As such, the B1-01 completion condition meets all requirements for continued use for Class 1 Underground Injection Cell well under Permit AK-11001-A.

SAVANT ALASKA DISPOSAL STORAGE VOLUME and ESTIMA E of FRACTURE GROWTH Vertical Fracture Extension. As part of B1-01 s irveillance in 2014, a Halliburton Spectra Flow Log was run on 5 April 2014 as a water flow log tool to ched for up -flow behind the 9%" casing. Savant also reviewed surveillance flow log reports prepared by Sava t in 2012, and BPXA in 2004, 2008 and 2010. No upward water movement was detected in water flow logs. This indicates water stayed within the permitted injection interval and there was no apparent vertical fracture extension. The next water flow log is scheduled for 2016. Horizontal Fracture Extension. Plotted volum s injected and estimated radii suggest radius assume uniform radial injection. To that end, Savant revieweq past BPXA and Savant annual performance reports for 2004, 2007, 2010, 2011, 2012 and 2013. Report data is summarized below, along with 5 months data from 2014.

This is equivalent to a radius of 579 feet aroundlthe wellbore at the perforated interval. UPDATE of OPERATIONAL PLANS The Badami field was restarted on November 5, 2010 after a three year warm shutdown. Badami B-01 has since been used primarily for produced water and camp waste disposal. Savant proposes to continue using 131- 01 for the same. No drilling cuttings will be disposed. Since taking over operations, Savant replaced the original Ball Mill facility fuel -fired glycol boiler with an electric boiler and repaired a storage tank. Sa ant also purchased and installed a heat exchanger. The new boiler, repaired storage tank and heat exchanger are scheduled to be connected in August to a downhole curtain string in the B1-01 outer annulus that r ns to 2,088 feet MD. This will help provide freeze protection to the lines leading to the well and downhole casings within permafrost. UPDATE of RECORDKEEPING PROCEDURES The B1-01 Class I Injection Well Permit (AK-11601-A) states in Part 1E 9.b that Savant, as "...permittee, shall retain records concerning the nature and composition of all injected fluids until three years after the completion of plugging and abandonment..." These records include North Slope Manifests, C�uarterly Injection Reports and Annual Reports. Relative to such records generated by past owner and operator] BP Exploration (Alaska), Inc. (BPXA), Savant took the following steps in early 2014 to meet this requirement. 1. Collected all hard copies of these records found at the Badami Central Production Facility (BAD-CPF), and especially the BAD-CPF Ball Mill. s 2. Requested hard copies and electronics copies of the same records from BPXA since injection started in 1997. 3. Ensured all similar records generated by Savant were available and accounted. As Part 1E 9.b does not require original record (hard copies) to be retained, Savant then proposed to manage such records as follows. 1. Scan all BPXA records in our possession and retain them electronically thereafter. Destroy the original hard copies 2. Retain hard copies of Savant records) for 1 year, and then scan them and retain them electronically thereafter. 3. Destroy the original hard copies. Savant gained approval from EPA on 29 April scanning old records. 14 to institute the new recordkeeping procedures and is now 4 • 1:1 m g00000000�noo" v a v N N a ry ry N ry N rn N a O m m E`o a N N N �-I rl N ey fi rl 'i rl 09 a a m v 0 1117 m M m M M N N .n v a w m A 0p M Ott M .V N 1p o0 a� '-I N n a A p � M a` O F � d E N a E " O o �noo�n0000�n�n�oM o o 0 o o o 0 o o M v A � N � o 0 i � � M a •- CL c u N of o as aN o.�vmoo O m m m mmrvof C C O O pdp A .

(BPXA) submits the attached quarterly report to the Environmental Protection Agency (EPA). The reporting period for this report is February 1, 2010 to April 30, 2010. The EPA requested we use-this reporting period by letter dated November 6, 1997. The quarterly report contains the following information: Monthly average, maximum and minimum values for injection pressure, rate, and volume reported on INJECTION WELL MONITORING REPORT (EPA Form 7520-8). 2. Graphical plots of continuous injection pressure and rate monitoring are presented on the "Honeywell Truline Daily Charts." These charts record the injection rate and pressure for a running 24-hour period, as well as keep a running total for the actual volume injected during a month. Please note that a summary of the waste manifested to the Badami Grind and Inject Plant is included on the "Monthly Manifested Volume by Waste Composition Form." This report shows the volume of waste manifested for each listed composition during the given month. The Daily Chart, from the Honeywell recorder, records the actual volume injected down hole. Please note that there is a difference between the total monthly volumes because not all fluids are manifested to the facility. In addition to the manifested waste, the Daily Chart records all Peter Contreras, Gro~Water Protection Unit • U.S. Environmental Protection Agency May 17, 2010 Page 2 water flushes used to displace the well over to clear fluids (water) after any injection of solids laden fluids, viscosity pills used to keep a spacer between fluids with suspended solids and lighter fluids which have little or no viscosity, and hourly water injections that verify surface lines are not freezing during periods of slow injection activity. These volumes are operationally necessary and are not manifested waste. In addition, a record and explanation of all chart upsets during the month is included in the report. Please note that there are days when no injection activity takes place at the facility. Days where no injection takes place are noted on the monthly sheets that record chart upsets. 3. Electronic monitoring data. 4. Physical, chemical, and other relevant characteristics of the injected fluids are included in "Drilling Fluids Reports" and "Fingerprint Data" in the attached report. 5. No well work over or other significant maintenance of downhole components was conducted during the reporting period. 6. A mechanical integrity test (MIT) was conducted on the inner annulus (IA) on February 9, 2010 to determine if well integrity was maintained. This test was conducted after the annulus pressure of 500 psi was exceeded. See #8 below and attached notification to the EPA submitted on February 10, 2010. 7. The injection rate limits of 5 barrels/min, 65,000 barrels/month, and injection pressure limit of 3000 psi were not exceeded for the reporting period. 8. On Saturday, February 6, 2010 at 6:30PM the high level alarm on the glycol recirculation tank tripped and automatically closed the curtain string and suction discharge (supply and return) line valves to the glycol recirculation tank. An estimated 5 barrels of glycol were in the tank. BPXA was injecting waste fluids at the time. The annulus pressure gauge was bouncing at and around 500 psig during the injection right before BPXA stopped injecting and shut-in the well. The pressure was Peter Contreras, Gr~ Water Protection Unit U.S. Environmental Protection Agency May 17, 2010 - Page 3 at or just above 500 psig on and off for an estimated 30 minutes between 6:30PM and 7:OOPM. There was no other exceedence of the 500 psi annulus pressure limit.

The reporting period for this .annual report is June 1, 2004 through May 31, 2005. Attached is monthly injection rate and performance data. A surveillance log was run during the reporting period. A water flow log and temperature log was performed during the September, 2004 barging season which confirmed that injection continues to stay in zone. Fill depth was also determined at that time. Copies of the logs and a descriptive report were submitted to the Commission in October, 2004. A Mechanical Integrity Test (MIT) of the inner annulus was performed on January 30, 2005. The AOGCC representative waived the right to witness the test. The mechanical integrity of B1-01 was demonstrated and no communication from the inner annulus to the tubing or outer annulus was evident. Based on a cumulative injection volume of 804,750 barrels into the well, it is estimated that the fluids occupy a total volume of 16.7 million cubic feet within the disposal interval. This is equivalent to a radius of 491 feet around the wellbore. As an update of operational plans for B1-01, we inform you that BP is preparing to restart production at Badami in late summer, 2005, when regulatory and technical requirements are in place. In addition, BP is evaluating the use of recent technology, such as horizontal drilling, to further develop the reservoir. Should new reservoir modeling support it, two wells may be drilled early in 2006 during the ice road season, Mr. Dan Seamount • June 30, 2005 Page 2 and if they are successful, up to six more wells in 2007 are possible. These plans for drilling are in the evaluation stage. Injection levels into B1-01 are likely to increase as Badami moves from warm shutdown to restart status, and return to the levels of injection seen in 1998 should drilling operations resume. If you have any questions, please contact me at (907) 564-5210 or Ms. Alison Cooke of my staff at (907) 564-4838. Sincerely, !.'~ Stan F.

There are numerous different versions of wording used for each of the rules that create confusion and inconsistent implementation of well integrity requirements for injection wells when pressure communication or leakage is indicated. In several injection orders, there are no rules addressing requirements for notification and well disposition when a well integrity failure is identified. Wording used for the administrative approval rule in injection orders is similarly inconsistent. The Commission proposes these three rules as replacements in all injection orders: Demonstration of Mechanical Integrity The mechanical integrity of an injection well must be demonstrated before injection begins, at least once every four years thereafter (except at least once every two years in the case of a slurry injection well), and before returning a well to service following a workover affecting mechanical integrity. Unless an alternate means is approved by the Commission, mechanical integrity must be demonstrated by a tubing/casing annulus pressure test using a surface pressure of 1500 psi or 0.25 psi/ft multiplied by the vertical depth of the packer, whichever is greater, that shows stabilizing pressure and does not change more than 10 percent during a 30 minute period. The Commission must be notified at least 24 hours in advance to enable a representative to witness mechanical integrity tests. Well Integrity Failure and Confinement Whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, log, or other evidence, the operator shall immediately notify the Commission and submit a plan of corrective action on a Form 10-403 for Commission approval. The operator shall immediately shut in the well if continued operation would be unsafe or would threaten contamination of freshwater, or if so directed by the Commission. A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for all injection wells indicating well integrity failure or lack of injection zone isolation. ~J • Administrative Actions Unless notice and public hearing is otherwise required, the Commission may administratively waive or amend any rule stated above as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in fluid movement outside of the authorized injection zone.

Main points - Demonstration of Tubing/Casing Annulus Mechanical Integrity - standardizes the wording used for mechanical integrity demonstrations, and establishes abililty to grant alternate methods (e.g., temp survey, logging, pressure monitoring in lieu of pressure testing - specific to AIO 2C for Kuparuk, there is wording that is more appropriately included in Weli Integrity Failure (i. e., more frequent MITs when communication demonstrated) - establishes more frequent MIT schedule for slurry injection wells (every 2 yrs) which is consistent with our current practice (but not addressed in regulations) Well Integrity Failure - retitles to "Well Integrity Failure and Confinement"; inserted language regarding injection zone integrity (see DIO 25 and 26) - consistent language regardless of type of injection (disposal, EOR, storage); - eliminates requirement for immediate shut in and secure; allows continued injection until Commission requires shut in if there is no threat to freshwater; - eliminates delay in notifying Commission after detect leakage or communication ("i.e., "immediately notify"); - removes language about notifying "other state and federal" agencies; - requires submittal of cocTective action plan via 10-403; - requires monthly report of daily injection rate and pressures (tubing and all casing annuli); this is a requirement we currently impose when notified of leak or pressure communication; - notice and action not restricted to leaks above casing shoe as stated in several DIOs Administrative Actions 1 of 2 10/2/2004 4:07 PM [Fwd: Re: Consistent Wording for Injection~rs -Well Integrity ... • - adopts "Administrative Actions" title (earlier rules used "Administrative Relief'); - consistent language regardless of type of injection (disposal, EOR, storage); - uses "administratively waive or amend" in lieu of terms like "revise", "reissue", etc.; - adds geoscience to "sound engineering principles"; - language is more generic regarding fluid movement out of zone; existing versions mention varying combinations of protecting "freshwater", "aquifers", "USDWs"; "risk of fluid movement"; "fluid escape from disposal zone" Jim Regg John K.

For slurry injection wells, the tubing/casing annulus must be tested for mechanical integrity every 2 years. The MIT surface pressure must be 1500 psi or 0.25 psi/ft multiplied by the vertical depth, whichever is greater, must show stabilizing pressure and may not change more than 10% during a 30 minute period. Any alternate means of demonstrating mechanical integrity must be approved by the Commission. The Commission must be notified at least 24 hours in advance to enable a representative to witness pressure tests. Well Integrity Failure and Confinement The tubing, casing and packer of an injection well must demonstrate integrity during operation. The operator must immediately notify the Commission and submit a plan of corrective action on Form 10-403 for Commission approval whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, or log. If there is no threat to freshwater, injection may continue until the Commission requires the well to be shut in or secured. A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for all injection wells indicating pressure communication or leakage. Administrative Actions Unless notice and public hearing is otherwise required, the Commission may administratively waive or amend any rule stated above as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in fluid movement outside of the authorized injection zone. • • Standardized Language for Injection Orders Date: August 17, 2004 Author: Jim Regg Demonstration of Tubing/Casing Annulus Mechanical Integrity The mechanical integrity of an injection well must be demonstrated before injection begins, at least once every four years thereafter (except at least once every two years in the case of a slurry inf ectfon «•ell}, anal before returning_a «•ell to ser~•ice follo`vin~ a workover affecting mechanical integrity, .,~,, „*'.,,a.~;t ~;:;~:;~ ...,, ,'. ~,-. .~ ~~- *~ °~-• ~ ~ +: y , ULl(A U y~r(Ll ,] i"VTiiR RG'l.lYi~l-i"Vii['LjTC,. tTnless an alternate means is approved by the Commission mechanical integrity must be demonstrated by a tubing pressure test using a ?~-1-surface pressure ofn~ 1500 psi or 0.25 psi/ft multiplied by the vertical depth, whichever is greater, that shows stabilizing pressure that does~€~-may not change more than 10°re-percent during a 30 minute period. -4~= .. - The Commission must be notified at least 24 hours in advance to enable a representative to witness pressure tests.

John McMullen sent this to us, it's an order proposed by the AOGCC to replace the well integrity related language in the current Area Injection Orders. Listed below are comments, not sure who is coordinating getting these in front of Winton/Jim. Overall, looks okay from an Operations perspective. We do have a few comments, but could live with the current proposed language. Note the proposed public hearing date is November 4. The following language does not reflect what the slope AOGCC inspectors are currently requiring us to do: "The mechanical integrity of an injection well must be demonstrated before injection begins, at least once every four years thereafter (except at least once every two years in the case of a slurry injection well), and * before* ** 1 of 3 10/28/2004 11:09 AM [Fwd: Re: [Fwd: AOGCC Proposed WI Lame for Injectors]] ~ , return'.ng a well to service following a workover affecting mechanical integrity." After a workover, the slope AOGCC inspectors want the well warmed up and on stable injection, then we conduct the AOGCC witnessed MITIA. This language requires the AOGCC witnessed MITIA before starting injection, which we are doing on the rig after the tubing is run. Just trying to keep language consistent with the field practice. If "after" was substituted for "before", it would reflect current AOGCC practices. It would be helpful if the following language required reporting by the "next working day" rather than "immediately", due to weekends, holidays, etc. We like to confer with the APE and get a plan finalized, this may prevent us from doing all the investigating we like to do before talking with the AOGCC. "Whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, log, or other evidence, the operator shall_* immediately*_** notify the Commission" This section could use some help/wordsmithing: "A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for all injection wells indicating well integrity failure or lack of injection zone isolation." Report content requirements are clear, but it's a little unclear what triggers a well to be included on this monthly report. Is it wells that have been reported to the AOGCC, are currently on-line and are going through the Administrative Action process? A proposed re-write would be: "All active injection wells with well integrity failure or lack of injection zone isolation shall have the following information reported monthly to the Commission: daily tubing and casing annuli pressures, daily injection rates." Requirements for the period between when a well failure is reported and when an administrative action is approved are unclear. This document states "the operator shall immediately notify the Commission and submit a plan of corrective action on a Form 10-403". If we don't plan to do any corrective action, but to pursue an AA, does a 10-403 need to be submitted? The AOGCC has stated they don't consider an AA as "corrective action". Let me know if you have any questions.

Rule 4 of DIO 12 requires an annual performance report that includes "rate and pressure performance, surveillance logging, fill depth, survey results, and volumetric analysis of the disposal storage volume, estimate of fracture growth, if any, and updates of operational plans." The Alaska Oil and Gas Conservation Commission ("Commission") received from BP Exploration Alaska, Inc. ("BPXA") the annual Disposal Performance Report for the Badami Class I well, for July 1, 2003 through May 31, 2004. The report is dated June 28, 2004, and summarizes pressure and rate performance, mechanical integrity testing of Well B1-O1. Noted in BPXA's report is that fill depth tags, water flow logs, and temperature logs will be performed during July-August timeframe. Please note that the following addition information is required in conjunction with the planned submittal of a descriptive report (and logging/survey data) to meet the requirements of DIO 12 Rule 4: Summary of all well pressures (tubing, inner annulus; outer annulus); Estimate of fracture growth; Update of operational plans.

The reporting period for this annual performance report is July 1, 2003 through May 31, 2044. Attached is monthly injection rate and performance data. No surveillance logs were run during the reporting period. A water flow log and tempera#ure log will be performed later this summer during the July-August barging season to confirm that injection continues to stay in zone. Copies of the logs and. a descriptive report will be submitted to the Commission when complete. Fill depth will also be determined during this time. A Mechanical Integrity Test (MIT) of the inner annulus was performed on March 12, 2004 with AOGCC witness. The mechanical integrity of B1-01 was demonstrated and no communication to the tubing or outer annulus was evident. t, ~ ~ A Mr. Dan Seamount June 28, 2004 Page 2 Based on a cumulative injection volume of 776,800 barrels into well Badami B1-01, it is estimated that the fluids occupy a total volume of 16.2. million cubic feet within the disposal interval.

Class II oil field fluids may be injected in the Badami Unit WD-1 and WD-2 wells, in conformance with Alaska Administrative Code Title 20, Chapter 25, for the purpose of disposal into strata which correlates with the Ugnu-basal Sagavanirktok Formation intervals between 5926'-7720' MD and the mid-Sagavanirktok Formation between 4450'-5526' MD in the Badami #4 well. Disposal injection within the mid-Sagavanirktok Formation must be specifically approved by the Commission, and may be further conditioned by administrative action after review of injection performance in the Ugnu-basal Sagavanirktok Formation. Rule 2 Demonstration of Tubing/Casing Annulus Mechanical Integrity The tubing/casing annulus must be tested every two years for mechanical integrity in accordance with 20 AAC 25.412. Rule 3 Well Integrity Failure Whenever disposal rates and/or operating pressure observations or pressure tests indicate pressure communication or leakage of any casing, tubing or packer, the operator must notify the Commission on the first working day following the observation, obtain Commission approval of a plan for corrective action and obtain Commission approval to continue injection. Rule 4 Surveillance A baseline temperature survey from surface to total depth, initial step rate test to pressures equal or exceeding maximum injection pressure and pressure falloff are required prior to initiation of disposal injection. Regular fill depth tags are required at least once annually or as warranted following consultation with the Commission. Operating parameters including disposal rate, .disposal pressure, annuli pressures and volume of solids pumped must be monitored and reported according to requirements of 20 AAC 25.432. An annual performance report will be required including rate and pressure performance, surveillance logging, fill depth, survey results, and volumetric analysis of the disposal storage volume, estimate of fracture growth if any and updates of operational plans. Report submission will be on or about July 1. Rule 5 Administrative Action Upon request, the Commission may administratively revise and reissue this order upon proper showing that any changes are based on sound engineering practices and will not allow waste fluids to escape from the disposal zone.

(BPXA) respectfully submits the following annual performance report for the Badami Class I well. This submittal meets the reporting requirement in Rule 4 of Disposal Injection Order 12.001. The reporting period for this annual performance report is July 1, 2002 through June 30, 2003. Attached is monthly injection rate and performance data. No surveillance logs were run during the reporting period. A water flow log and temperature log were run on March 28 and 29, 2002. Copies of the logs and a descriptive report were transmitted to the Commission on May 1, 2002. The surveillance logs confirmed that there is no movement of fluids in vertical channels adjacent to the wellbore and that the confining zone is not fractured. Based on the surveillance log results and the low injection pressures and rates in the Badami 1-01 well, BP believes there is minimum fracture growth within the disposal interval. A Mechanical Integrity Test (MIT) was run on March 13, 2003. The mechanical integrity of the B1-01 well was demonstrated and no communication to the tubing or outer annulus was evident. A copy of the MIT report is attached for your convenience. The fill depth was not determined during the reporting period. Ms. Sarah Palin July 2, 2003 Page 2 Based on a cumulative injection volume of 728,041 barrels into well Badami 1-01, it is estimated that the fluids occupy a total volume of 15.14 million cubic feet within the disposal interval. This is equivalent to a radius of 468 ft around the wellbore. The Badami Field is preparing to go into a warm shutdown. The injection volumes in the Badami 1-01 well will therefore be decreasing in the future.

The schedule for future e-1Ïne survey work at Badami is now extended to once every two years. Badami will need an AOGCC waiver from the annual requirement Disposal Injection Order No. 12, Rule 4 states, '"Regular fill depth tags are required at least once· annually or as warranted following consultation with the Commission." On March 18, 2002, the Environmental Protection Agency modified the surveillance logging requirements in the Badami Class I Well Permit No. AK-1-I001-A. The new requirement states that, "fluid movement tests are required annually during drilling operations and every other year after drilling operations have been concluded." In order to make the permit requirenlents consistent, BPXA requests that the Alaska Oil and Gas Conservation Commission amend the requirement in DIO No 12, Rule 4 for a fill depth tag to annually during drilling operations and every other year after drilling operations have been concluded.

(BPXA) is in the process of responding to issues raised during a third party environmental management audit by Arthur D. Little, Inc. On March 20, 1998, Alison Cooke of my staff met with you to discuss certain preliminary findings relating to underground injection at Badami. At your suggestion, we are providing the following information to summarize the audit findings. The auditors made the following comment about Badami: Well Disposal Authorization (Good Management Practice) The injection facility is regulated by the EP A, the Alaska Department of Environmental Conservation (ADEC), and the Alaska Oil and Gas Conservation Commission (AOGCC). The injection facility is used for disposing Class I and Class II non-hazardous wastes. The Badami Unit obtained permits from the EP A and ADEC permitting the disposal of Class I and Class II wastes, and a Disposal Injection Order No. 12 from the AOGCC for the operation of the injection facility for Class II wastes. The Oil and Gas Conservation Commission Disposal Injection Order No. 12, however, has not been modified nor does the Badami Unit have documentation supporting that the injection facility is authorized to dispose Class I oil field wastes. [Good Management Practice related to 20 AAC 25.252(a) and AOGCC, Disposal Injection Order No. 12, Conclusion 3]. As we explained to the auditors, Class I disposal is clearly authorized by the EP A permit. BPXA also recognizes that the Commission can only authorize injection for Class II wells in their Orders. Copies of the Class I Underground Injection Control (UIC) permit are kept on site at Badami. RECEIVED tlPr{ G2 199~C./~:~~\~¡\~E['; JUN ~~ 0200¿1 Alaska Oil & Gas Cons. Commission AnrI1nr;Jnp. · !. M,~, David Johnston I . l\i¡~lCh 30, 1998 , Page 2 ') ') BPXA applied for the Class II Disposal Injection Order as a backup to the Class I permit. Without this backup, any delays or problems with the Class I permit application would have left BPXA without a viable option for disposal of drilling wastes at Badami. We believe that AOGCC understood that Class II disposal would only be required as a contingency. AOGCC issued Disposal Injection Order No. 12 without a specific expiration date, and did not rescind it when the Class I permit was finally approved. This means that the notification and reporting requirements of the Injection Order are still in effect. However, AOGCC has agreed that copies of the Class IIEP A reports would satisfy the reporting and notification requirements of the Disposal Injection Order. Since the Class I permit is both broader in scope (wastes approved for disposal in a Class II well can be accepted) and more stringent than the Class II Disposal Injection Order, it is considered the primary authorization for underground disposal. We would appreciate your recommendations whether modification of the Disposal Injection Order should occur to recognize other permitted authorities, such as the EP A Class I DIC permit. We request a written response at your earliest convenience so that we may bring this particular issue to closure. If you have any questions, please contact Ms. Janet Platt at (907) 564-5501.

Standard Alaska Production Company.(SAPC) requested the Alaska Oil and Gas Conservation Commission to issue an Area Injection Order permitting the underground injection of fluids within the Western Operating Area and K Pad Area of the Prudhoe Bay Unit for the purposes of enhanced recovery and the disposal of non-hazardous oil field waste fluids. 2. Notice of an opportunity for a public hearing on June 25, 1986, was published in the Anchorage~Times on May 22, 1986. 3. Neither a protest nor a request for a public hearing was timely filed. Accordingly, the Commission will, in its discretion, issue an order without a public hearing. FIND INGS : 1. An order permitting the underground injection of non-hazardous fluids on an area basis, rather than for each injection well individually, provides for effi- ciencies in the administration and surveillance of underground fluid injection operations. 20 AAC 25.460 provides the Commission with the authority to issue an order governing underground injection operations on an area basis. 2. The Western Operating Area and the contiguous K )'~d Area constitute a compact "project areau for the operat¡ion of a portion of the Prudhoe Bay Unit and can readily þe described by governmental subdivisions. The Proje~t Area is operated by a single operator. ' SCtÜ\H~ED JUN 3 0 20D4 ,~ ) Area Injection Oraer No. 3 Page 2 ( July 11, 1986 10. 3 . The Project Area encompasses approximately the western one-half of the Prudhoe Oil Pool. The Project Area includes all existing injection wells and injection well· sites planned for enhanced recovery from this portion~of the Prudhoe Oil Pool. The Project Area includes all existing injection wells and injection well sites planned for disposal by injection into Cretaceous and Tertiary strata of oil field waste fluids developed from the operation of this portion of the Prudhoe Bay Unit. 4. Those portions of aquifers described by a 1/4 mile area beyond and lying directly below the Project Area are exempted for Class II injection activities by Aquifer Exemption Order No.1. 5 . · Less stringent requirements for well construction, operation, monitoring and reporting of injection op- erations may be more appropriate than would be required when injection occurs into, through or above portions of aquifers not exempted. 6.

The interval is present within the Badami No.4 well from 5526'-7440'-MD. 9, .-\ regionally extensive. dominantly shale interval \vithin the basal Sagavanirktok Formation is present within the Badami No. -+ well from 5526'-5926' MD. This interval contains an aggregate thickness of shale in excess of 250', 10. The basal Sagavanirktok Formation also contains numerous intervals of laterally extensive sandstones. The log character of these sands is similar to those \vhich have demonstrated a large capacity to accept disposal fluids in other North Slope Fields. 11. \10st of the Class II disposal fluids from other North Slope Fields has been confined by similar lithologic and stratigraphic intervals as those present within the U gnu and basal Sagavanirktok Formations underlying the Badami Unit. 12. Overlying the basal Sagavanirktok Formation. between 4450'-5526' MD interval in the Badami No. -+ well. is an interval of approximately 65 percent highly porous and permeable. laterally continuous. t1uvial to shallo\\: Il1arine sandstones. 13. A predominately mudstone interval exists between 3892'-4450' MD within the Badami No. -+ well. It is considered the shallowest potential contìning zone in the well. The gross lithologic character of this interval is persistent through the proposed \VD-l and WD-2 vicinity. 14. The 3892'-5526' MD interval in the Badami No. -+ is designated the middle member of the Sagavanirktok Formation for the purposes of this order. 15. BPX does not plan to inject t1uids within the middle member of the Sagavanirktok Formation unless injection in the U gnu -basal Sagavanirktok Formation interval is unsuccessful. 16. BPX \Nill run cement quality logs within the surface casing and long string of each well. The Commission will evaluate the logs and cement records to determine the adequacy of the cement to isolate disposal intervals. 8Cl\.NNEL) JUN 3 C 20D~· J) Disposal Injection Order No. 12 August 5. 1997 Page 3 1 7, Completion plans entail 20" conductor set at 110' subsea (SS). 13 3/8" surface casing set at ...../-4230' SS and cemented to surface and a long string of 9 5/8" casing set at +/-7500' SS and cemented back into the surface casing. 18. BPX will test tubing and casing integrity according to 20 AAC 25.412 prior to initiation of disposal operations and every two years thereafter. úV Disposal material will consist of Class II fluids generated from drilling. production. workover and completion operations. The typical disposal stream will consist of seawater. produced and fresh water. drilling mud. drill cuttings. workover t1uids. stimulation materials. vessel cleaning material. formation sand. cement and other nominal Class II waste. Constituent volumes will vary depending on drilling. workover. stimulation and maintenance activity. 20. BPX expects to dispose of approximately 12.500 cubic yards (60.100 barrels) of solids during the life of the project. 21. A v.erage disposal rate will be nominally 3000 BPD (~2 BPM) during development drilling and at other peak periods. The operator expects to average 300 to 500 BPD over the project life. Maximum instantaneous disposal rate is anticipated to be about 5 BPM. 22. Maximun1 operating pressure will vary depending on depth and the condition of the fon11ation. Surface pressure is expected to range from 1800~3300 psi when disposing in the U gnu-basal Sagavanirktok interval. with a corresponding bottom hole pressure (BHP) of 4950-6450 psi. In the mid-Sagavanirktok disposal intervals. estimated surface pressures will be l300~2800 psi and estimated BHP 3500-4900 pSI. 23. BPX expects to maintain injectivity by occasionally stimulating the disposal interval. Stimulation activity will entail pumping solid free tluid to disperse solids. chemical treatments and elevating pressure to breakdown the disposal interval. 24. Fracture propagation within the disposal interval is an integral part of the process of placing \vaste tluids into the disposal interval. Fractures will be created as the disposal zone begins to plug. Fractures or disaggregation of the clogged pores and rock matrix provide pathways to transport waste t1uids to undamaged" storage volume within the disposal zone. 25. Estimates of likely vertical gro\\1h of fractures in the upper disposal interval is approximately 250'. based on rate and volume estimates. 26. Periodic surveillance of disposal operations will ensure waste tluids are contained \vithin the disposal interval. Surveillance methods include temperature surveys. pressure transient tests. step rate tests. thermal decay time logs. disþersal rate and pressure monitoring, mechanical integrity tests and tagging effective depth to determine till buildup.

Evaluation ot operation performance and reservoir surveillance \\"ill aid in preventing fracturing of the confining zones. 29. BPX calculated formation t1uid dissolved solid content from existing well control within the Badami Unit through analysis of geophysical logs calibrated to a single water sample from 4982' ]\1D in the Badami No.5 well. Calcùlated salinity of formation waters ranged from 18~000 mg/liter to 48.000 mgl1iter for formations between 2000' and 7.200' SS. 30. The U,S. En\"ironmental Protection Agency (EP A) determined aquifers with total dissolved solids of less than 10.000 mg/liter are not present \\'ithin the Badami Unit in either the L- gnu or the Sagavanirktok Formations. 31, In correspondence dated May 12. 1997. the EP A notiíìed BPX of its determination that no underground sources of drinking water (USDWs) \vere present in the Badami U nit.

This well is currently operating under EP A requirements as a Class I well. Class I reporting requirements for the B 1-01 well are more rigorous than those for Class II wells. The intent of DIO # 12 would be met if BPXA submitted to the Commission those reports required by EP A. Therefore, in the interest of streamlining reporting, the Commission will accept the EP A notification and reporting requirements as specified in the Class I permit. In the event that well B 1-0 1 is operated as a Class II well, the Commission would require BPXA to operate under the constraints of DIO # 12. cc: Jonathan Williams, USEP A Region 10 ~~Cl.\f,\n~H::t·.

(BPXA) requests that the Commission consider receiving the reports required by the Environmental Protection Agency (EPA)Clas.s I well permit for the Badami 81'-01 well in lieu of the reports required by the Disposal Injection Order (010) No. '12. Ms. Alison Cooke of my staff discussed this suggestion with Mr. Blair WondzeH on December 3, 1997. Mr. Wondzell suggested we follow up with a written request to the Commission for concurrence. While BPXA are operating under the EPA Class I requirements at Badami, we would like to copy the Commission on all EPA notification and reporting requirements. In the event that we cease injection of Class I waste for any reason and operate under the AOGCC 010, BPXA would then meet the reporting and notification requirements in the 010. BPXA makes this request in order to streamline and ensure compliance with reporting and notification requirements for the Badami B1-01 injection well. Currently the well is regulated by the EPA Class I well permit, the AOGCC 010, and an Alaska Department of Environmental Conservation Wastewater Disposal Permit. Although we worked with the agencies to negotiate consistent requirements in these permits, there are some differences in the specific information requested, the frequency of reporting (monthly, quarterly, annually), and the timing for R E (- E ,- V E D submittal of information.

Mr. Crandall requested that BPX address the maximum operating pressure, vertical fracture growth, well surveillance, and the Area of Review. They are each discussed below: 1) Maximum pressure The normal operating pressure of the Badami Class I well will be below 3000 psi. There are two situations, where the maximum well pressure might go up to 4800 psi for a short period of time. The first situation might be at the initial breakdown of the formation if there is near wellbore damage or plugged perforations and the extra pressure will allow these to breakdown. The second situation is at any time in the well's life if the solids injection causes perforation plugging, there will be a need to apply extra wellhead pressure (up to 4800 psi) to overcome the blockage. f~EGEIVED .I~ :\' 2.0 1997 A'aska Oil & Gas Cons. ComHl\S~' SC.AN,Nf!1EÞ~'~ ~i 0 2004 ) ) Badami 010 Page 2 June 18, 1997 2) Fracture Growth from the upper injection zone Field evidence and laboratory experiments indicate there is no basis to expect that the upper confining zone will be penetrated. Should the upper injection zone be used for solids storage, it will be perforated in its lower few feet of section. This will provide approximately 950 feet of separation between the perforations and the base of the confining zone. Comparing the Badami disposal operation with other projects indicates vertical growth might be in the 250 foot range. A maximum case might be 500 feet. This generates a safety factor between 2 and 4. The relationship of the Badami project with others can be seen on the following table. Average Total Max Injection Solids Fracture Fracture Project Rate Volume Length Height (BPO) (Cu Yds) (Feet) (Feet) Prudhoe OS4-19 20 400,000 2000 1600 Jasper County, Tx. 10-15 1,500 1200 confined by shales Prudhoe CC-2 2.5 130,000 800 300 Badami 1 12,500 3) Badami Class II well surveillance The Badami waste injection well has been designed in a very conservative manner to ensure that there is little risk of a broach or fracturing into or through the confining zone. This has been achieved by placing the well at over 2000ft from other wells and limiting the injection rates, thus inducing a smaller injection domain. The well has also been designed with the casing cemented back to the surface casing shoe, which is placed across the confining zone. ·::::;~..t.,;\!i\IEr.\ .JUN 3 G 2004 .REt¡r:i\/~D l~ ~: .\ &~ ~~ \ :.! Ii 2 0 1997 Alas.ka ,Oil.& Gas Cons. .CQnmÜs$l~ Anchoragg ) ) Badami 010 Page 3 June 18, 1997 This conservative approach allows BPX confidence in ensuring the injection domain is contained. Normal mechanical integrity tests will be performed on the well to identify any mechanical failures. The well will also be monitored for any unusual changes in injection pressure and rate, which might indicate loss of containment, such as continual lowering of injection pressures. Logs that might be run to investigate unusual well responses are temperature or borax logs. These are both near wellbore logs and could help identify channels behind casing, but from previous experience are unlikely to give fracture height. Another form of monitoring is a pressure falloff test, several of these will be performed in the well's life. The pressure falloff test should help delineate the maximum dimension of the injection domain, if not the exact shape. As discussed with Mr. Crandall, BPX would like to meet with the AOGCC to discuss the surveillance plan for the Badami disposal well. 4) Area of Review There are no existing or planned wells with a quarter mile radius, measured at the top of the confining zone, of the Badami disposal well. Therefore, there are no wells within the Area of Review (AOR) for Badami. Under separate cover BPX will forward a map which shows the AOR. Inquiries regarding this clarification should be directed to Ms. Alison Cooke at this office. Sincerely, ~ REGEIVED David A. Wallace HSE Manager .. 20 1997 Alaska Oil & ¡'~ ~ ,., - . . uas Lons.

CQ.~~$l~Uì , ~hQrag.ø " ",1->'"' BP Exploration (Alaska) Inc.(BPX), as operator of the Badami unit, hereby makes application for a disposal injection order to authorize injection of Class II drilling and production wastes into strata within the unit boundary. As BPX has discussed with Ms. Wendy Mahan of your staff, a Class II disposal injection order is needed to provide a contingency for our Badami project in the unlikely event that the Environmental Protection Agency (EP A) does not issue a Class I well permit prior to commencement of drilling operations. Development drilling will begin on or about September 1, 1997, and a disposal well will be the first well drilled. A ruling is requested that will allow for appropriate planning and other activities to occur before that time. Suitable injection zones have been identified between 4900 and 7350 feet. They are bounded by arresting zones and upper and lower confining zones. The waste disposal system will consist of a solids grinding plant, a pipeline network, manifold hookups, tanks, pumps, and a Class II well. The injection stream will consist of drilling muds - 'I¡"---, q II ¡ '\ n '2" (\[1 ~ SC/\Nf\H::)o" , ,,[I.)

The EP A Region 10 office has ruled that there are no USOWs within the Badami unit boundary (May 12, 1997 correspondence from Mr. Jonathan Williams, EPA, to Ms. Alison Cooke, BPX). A copy of the EP A letter is attached for your reference. The application and supporting information was prepared in accordance with AAC Title 20, Chapter 25.252. It shows that wastes will be confined to the injection zone and contamination will not occur above the confining zone.

There will be approximately 36 conventional wells drilled from a central pad. Surface casings will be set in a confining zone at approximately 4200 feet. The first well drilled will be for disposal of Class IT wastes. It will be directed in a sout~erly direction away from the other wellbores The spider map shows two disposal wells, WD-l at an azimuth of 250 degrees and well WD-2 at 165 degrees. Please note that the location named WD-2 on the spider map will probably be drilled first, in September, 1997. Throughout the remainder of the document this well location has been renamed WD-l. The WD-llocation (identified on the spider map) will be referred to as WD-2, and would not be drilled unless required at a later date. There are no existing wells within 1A mile of the proposed injection points at depth. The closest existing well is Badami #1 which is 4200 feet from WD-l and 3200 feet from WD-2 at the proposed upper injection interval at 4950 feet (subsea). All of the proposed producing wells will maintain a minimum offset of 2000 feet at the upper injection zone. The lower injection zone at Badami #1 is 6000 feet from WD-l, and 5000 feet from WD- 2. Surface Owners and Operators 20 AAC 25.252 (c) 2&3 The State of Alaska is the only surface owner within or adjacent to the Badami Unit and no other operators are in the development area; therefore, no copies of the application need to be distributed and no notification affidavits are required. 0C!\~\~NE[> ~ßVN 3 0 2001:1 ) ) Geolofic Details Maps, Cross Section, Well Lo~, Structure and Stratifraphy 20 AAC 25.252 (c) 4 Introduction Following is a description of the geology of Tertiary (Paleocene to Oligocene) age stratigraphy across the Badami Unit Area with specific reference to proposed injection and confining intervals. A series of informal key markers are identified and correlated from wireline logs. These are summarized in the following table and are shown on the . type log (Exhibit 3) and the generalized cross section (Exhibit 4). These markers are strictly litho-stratigraphic but can be correlated regionally. The intervals comprise siliclastic rocks in the West Sak, U gnu and Sagavanirktok Formations (FM) overlying a thick shale sequence called the Canning Formation (equivalent in part to the Seabee shale to the west). Structure maps on key marker horizons are presented in Exhibits 5-7. The overall sequence including the Canning, West Sak and U gnu strata comprise the final regressive sequence in the Middle Brookian of Tertiary age (Paleocene to Middle Eocene). The overlying Sagavanirktok strata comprise at least two cycles of transgression-regression in the Upper Brookian section of younger Tertiary age (Upper Eocene to Oligocene). The Middle Brookian sequence shows a pronounced upward shallowing cycle starting with deep water marine shales (Canning FM) followed by shelf shales, siltstones and very fine to medium grained sandstone (West Sak FM) and capped by shallow shelf and coastà1 plain / fluvial fine to medium grained sandstone (U gnu FM). The strata in this sequence are moderately consolidated. Sandstone porosity is susceptible to degradation by compaction (rather than cementation) because of the high content of ductile lithic sand grains. The Upper Brookian sequences begin with a major shale unit which is the Fesult of a transgression creating a subsiding muddy shelf. This is overlain by a sand unit recording fITst regression and then transgression sequences. The sand is fine to coarse grained (some gravel) and of fluvial to shallow shelf origin. Continued transgression resulted in shelf mud deposition creating a thick shale unit which is overlain by 3000 to 4000 feet of largely coarse sand and gravel resulting from the final regressive phase of the Sagavanirktok. SCANNED JUN 3 {) 200~ ') 0) The Sagavanirktok sands and gravels are loosely consolidated and have maintained much of their original porosity framework owing to their shallow burial. The base of the pennafrost intercepts this coarse member of the Sagavanirktok and is evident in all wells in this coastal area. Additional discussion, maps, and x-sections on the geologic sequence are included in the Class I Industrial Well Pennit Application submitted to the EP A and copied to the Alaska Oil and Gas Commission in April, 1996. Reference is ~ade to Section 3 and Appendix C of that document.

Other wells close to the development area are Badami #1, #2, #5, and Mikkelsen Bay State #1. These wells best depict the expected properties of the confining, arresting and injection zones. Basal Confininf Zone Canning Formation: In the Badami Unit area the name Canning Formation is used for the thick (2,500-3,000 foot) shale unit which lies benea~ the West Sak Formation and above the Hue Shale (includes the "HRZ" unit). In the Prudhoe Bay Unit this unit is called the Colville Mudstone or the Seabee Formation. In this area, approximately the lower third of the Canning Formation is Upper Cretaceous in age and the upper two thirds is Lower Tertiary (Paleocene to Eocene) age. This thick unit contains chiefly shale and shaley siltstone originally deposited as muddy sediments spread on a deep marine slope and basin plain with maximum water depths of around 3,000 to 4,000 feet. The marine slope prograded to the northeast. These slope sediments are overlain by deposits of the marine shelf, shoreline and coastal plain environments. The transition from the slope to the shelf is marked by the gradational contact (marker 9) of the Canning Formation and overlying West Sak Formation. The shales and muddy siltstones of the upper Canning Formation are regionally continuous. The contact with the overlying West Sak Formation (marker #9) is gradational and subject to irregularity caused by inter-tonguing of West Sak fine grained sandstones with the underlying Canning shales. For this reason a structure map of marker #8, (Exhibit 4) which is a regionally correlative marine shelf shale within the West Sak Formation, is used to better depict the structure of beds near the contact. Proposed Injection Zone The proposed injection zone includes the section from the base of the U gnu Foimation (marker 7) to the top of a thick regressive sandstone unit in the Sagavanirktok Formation (marker 3). This encompasses about 2300 to 2400 feet of section; however, a major _ barrier shale unit approximately 1750 feet in thickness divides the Ugnu Formation from the overlying Sagavanirktok sandstone unit. Ugnu Formation: In the Badami Unit area the Ugnu Formation is 200 to 250 feet thick and composed predominantly of sandstone with interbeds of mudstone and siltstone with rare thin coal beds. The top of the U gnu (marker 6) is picked at the abrupt contact , (indicated by wireline logs) with a regionally correlative mudstone. This change in SCANNEL: ,JUN ~:~ 0 2nD¿~ ) ) lithology is indicative of the beginning of a marine flooding event and the end of the Middle Brookian regressive episode. The U gnu Sandstone beds have a variety of wireline log signatures indicating shifting environments of deposition ranging from fluvial, to marine deltaic channels, to shoreline, and shallow marine near shore sand bars. The coals and mudstone are consistent with deposits in bays, lakes and swamps characteristic of delta environments. The U gnu sands are loosely consolidated and apparently maintained significant original porosity and permeability (average 27% porosity and ±~SOmd permeability, range ISO to 750 milidarcies, based on log analysis of the four Badami wells). The interbedded mudstones should provide at least local barriers to vertical flow. Because of the relatively high net reservoir sand to gross interval (approximated at 40 to 60 percent) connectivity between U gnu sands~should be expected. The major shale barrier overlying the U gnu Formation provides confinement immediately above this injection zone target. The West Sak Formation and Canning Formation provide thick arresting and confining zones below the U gnu Formation. Major Shale Barrier: A basal Sagavanirktok unit of 1750 feet of shale and siltstone (with very rare and thin beds of sandstone) constitutes a major barrier within the injection zone. The unit records the major marine transgression at the beginning of the Upper Brookian during which aggradational deposits of mainly muddy sediment accumulated on a broad shelf. Several aggradation cycles are visible in the unit as "cleaning upward" sequences on the wireline logs (gamma ray decreasing upward; resistivity increasing upward), These sequences range from 100 to 400 feet in thickness and generally have a few thin beds. of very fine to medium grained sand interbedded with silt at the top. Near the top of this major shale barrier unit is a clay shale unit (about 200 feet thick) which has a much higher gamma ray reading. This is an apparent condensed clay which has règional extent, and its sharp base (marker 5) is used as a datum for log cross sections. The upper contact of the major shale barrier (marker 4) is picked at an abrupt gamma ray and resistivity decrease reflecting the clean sands and gravels of the initial regressive unit of the Sagavanirktok Formation. Sagavanirktok Initial Regressive Sandstone Unit: A zone about 300 to 400 feet thick of mainly unconsolidated sands comprise the top of the proposed injection zone. This upper target for injection is dominated by medium to very coarse sand with some gravel generally at the base of the unit. Thin interbeds of mud, silt and clay are present but do not appear to be laterally extensive. The unit is interpreted to be the product of fluvial channel deposition resulting from a sudden increase in sediment supply and possibly sea ~':"'(t--.^~~I" Be\~-, II'~ ilìl.j "J) ;~ ...,OO-í ~~'))~~:9!rè.B'\1~JC.~¡..~ ~..' ~J~" o'¡) l' t." '.."11 ') ) level drop. This thick basal unit of Sagavanirktok sand deposition is an extensive and correlative deposit within the Badami Unit The reservoir properties of the Sagavanirktok initial regressive sandstone unit are very good with average porosity of about 31 % and permeability ranging from 500 to 2500 milidarcies. The shallow depth of burial and coarse nature of the sediment have led to preservation of a very large amount of its original porosity and permeability. The unit also has a high net sand to gross content of about 70 to 90 percent. The upper contact (marker 3) and top of the proposed injection zone is picked at the base of the lowest major correlative mud bed of the overlying unit. The influx of mud as major units above the contact may indicate the initial onset of a slow marine transgression Upper Confininf Zone Sagavanirktok Upper Shale (Mud) Unit: Above the upper arresting zone a 300 to 500 foot thick unit of dominantly mud and muddy silt is present in the Sagavanirktok Formation across the Badami Unit area. This mud dominated unit constitutes the Upper Confining Zone. This upper shale unit is very similar in composition and log signature ("cleaning upward "cycles) to the major shale barrier which divides the proposed injection zone. The upper shale unit is interpreted to have been deposited on a mud dominated marine shelf during the maximum transgression of the sea. This led to the widespread mud deposition of uniform thickness.' Sand interbeds within this unit are rare within the Badami Unit development area but appear to thicken in wells at the northwest and west edge of the Unit area. At the top of the upper shale (marker 1) there is a correlative shale (mud) bed of75 to 125 feet in thickness. This shale results from the most widespread mud deposition prior to the beginning of marine regression and the upward increasing dominance of sand deposition. Structure Structure maps for marker horizons 1, 3, 8, and the base of permafrost are included. These maps were constructed from contouring well data and are not directly constrained by mapping of seismic data. There are s.ix wells (Badami #1, #2, #4, #5, West Mikkelsen #2 and Mikkelsen Bay State #1) within the Badami Unit outline and effectively three wells (East Mikkelsen #1, West Mikkelsen #1 and #4) adjacent to the Unit. SC/\NNEIC" JUN J 0 200..~ ), ') The structural dip on the ~arker horizons is relatively simple with dips of about one to two degrees toward the northeast to east. Shallow horizons, such as marker 1, have dip generally toward the northeast. Progressively deeper horizons show dips to the east- northeast with the deepest, marker 8, showing predominantly east dip. Examination of the shallow horizons on the 3D-seismic data did not indicate any significant offsets due to faulting (See Exhibit 8). The structUral contour of the permafrost base is shown in Exhibit 9. Base-permafrost picks on thewireline logs depend primarily on the quali,ty of resistivity and sonic log measurements, as well as the sharpness of the transition from frozen to non-frozen sediments. Permafrost is present on land to depths of around 2000 feet. Offshore the base of permafrost begins to èlimb as the water deepens. The base is projected to be at 1600 to 1700 feet at the northern boundary of the Badami Unit. Occurrence of Hydrocarbons Within the Badami Unit area, there are no indications of trapped hydrocarbons in the upper part of the Canning Formation and shallower formations. Residual oil shows are present in some of the area wells in the West Sak below marker 8. Farther to the west (10 miles) in West Mikkelsen Bay #1 the residual oil shows are present throughout the West Sak fine grained sands. Although the possibility exists for gas hydrate to be trapped in Sagavanirktok sands and gravels at the base permafrost there is no indication of this type of hydrocarbon occurrence within the Unit area. Outcrops and Rechar~e None of these formations proposed as confining, arresting or injection zones outcrop in the general area. Within the Badami Unit the top of the Upper Confining Zone is in excess of 3300 feet deep and the top of the proposed Injection Zone is in excess of 4200 feet subsea. An examination of regional seismic lines shows that these zones come near or to the surface approximately 20 to 25 miles southwest of the Badami Unit. Approximately 10 to 15 miles southwest, the Upper Confining Zone and subsequently the Injection Zone is projected to intercept a 2000 foot thick permafrost zone. The thick permafrost (generally at 2000 feet or greater onshore) is considered a barrier to recharge and discharge.

This discussion details construction for well WD-l although there is a possibility the WD- 2 location will be drilled first. The drilling program calls for kicking out from the vertical at 500 feet, building angle to 35 degrees, and maintaining an accuracy that will allow for hitting within 200 feet of the target. All construction requirements exceed the specifications required by the State of Alaska regulations. The casing-cementing program is depicted in the schematic of Exhibit 10. The surface hole will be logged as specified to ensure that the surface casing shoe is set near the base of the confining zone and well bonded to the fonnation. This placement, plus the use of Class-G cement as the tail slurry around the casing shoe will ensure good zonal isolation up to the permafrost. A full logging program will be run in the lower hole. The long string,will be cemented with an excess volume to ensure bonding. Zonal isolation will be verified by cement bond logs. Both surface casing and long string integrity will be verified by pressure testing. The tubing by casing annulus will be isolated above the injection intervals by stabbing a tubing seal assembly into the injection packer's polish bore receptacle. A landing nipple will be installed in the tubing string below the pennafrost at 2200 feet. The annulus will be filled with gelled sea water with a diesel cap for freeze protection prior to initiating heated glycol circulation down the heater string. These fluids will be treated with corrosion inhibitor. The tubing and tubing by casing annulus will be pressure tested to 3000 psi. Should the well not pressure test satisfactorily the tubing will be removed and the problem corrected before the drilling rig leaves location. The well head assembly is shown in Exhibit 11. The wellhead, controls, arid monitoring instrumentation will all be enclosed in an insulated and heated well house. The lines to the well will be heat traced and insulated. ~~ ti'~-~'~ ~l ~),J c-] r'ìI¡ 20D'~ SCJ{~Ü~EL\; -:..11 ,.H~¡ \~))~) . ,.'-~ ') ) Proposed Drillin~ and Completion Profram : Well WD-l Surface location: (Approx.)

Class II wells are defined as wells which inject wastes brought to the surface in connection with oil and gas production, with natural gas or liquid hydrocarbon storage operations, and may be mixed with other wastes from plant operations; unless those wastes are classified at the time of injection as a hazardous waste under 40 CFR 261.3. Class II wastes acceptable for injection must originate down hole and will include the following: Water Based Cuttings Oil Based Cuttings Water Base Mud Oil Base Mud Well W orkover Fluids Water Gel Fresh or Sea Water Stimulation Fluid Frac Sand Crude Oil Diesel Methanol Production Vessel Sludge/Sand Production Line Pigging Waste Reserve Pit Meltwater Well Cellar Fluids Class II Contaminated Gravel Produced Water Cement Wastes Well Completion Fluids Rig Wash Class II Waste Rinsate Other Class II Wastes Typical Injection Stream The following typical disposal stream is projected for Badami over the life of the project. · Industrial waters consisting of sea-source, produced brine, fresh, and water gel ( 64 percent) · Water-based drilling mud (14 percent) · Water-based drill cuttings (2-3 percent) · W orkover fluids, crude oil, vessel sludge/sand, diesel, methanol, spent acid, cement, frac sand, snow melt and other minor waste streams (20 percent) ..- -, J' IN I '-ì n 20(1/1 5C¡\~H~H:J\ ,-l) \ ~:!! i." -,' : ) ) Injection Rates /' (fl.') 0y'~ ;-' 1/'" V "_,, The estimated maximum injection rate is 3000 BPD.

The following tabulation shows the range of injection pressures that are estimated to occur through the life of a single well. This includes the time from when it is initially completed in the deep interval, through abandonment of that interval as it might become plugged with solids, and further through its life as the shallower interval is used for storage. The intent is to use the lower interval as long as solids can be transported into and through the formation. However, progressive plugging may occur and ultimately further stimulations become ineffective, and a lockup situation evolve. That interval would then be abandoned. The range of injection pressures are relatively high, well above the fracture gradient for the receiving sands (0.65 psi/foot of depth). By necessity, the pressures must be at these levels since the receiving reservoirs must be fractured for a slurry-solids type placement process to work. It should also be emphasized that the expected pressures, as shown, reflect operation of a well when no major plugging of the wellbore or region adjacent to it has occurred. Periodically, the solids being transported and the filter cake additives in the mud will combine to begin a gradual plugging of the then-existing fracture faces and matrix porosity. When this occurs, if injection operations cease and the wellbore is not flushed adequately with .clear fluid, the pore throats and flow channels will become plugged. To, re-initiate communication with the reservoir, surface pressure may sometimes have to be temporarily surged above those pressures listed. This temporary surge acts the same as a stimulation procedure and flow can once again be established. This type of operation is typically done with clean brine. Except for these necessary brief stimulation exercises, it is expected that injection pressures would generally be at or below the indicated levels, which are viewed as maximum levels that would occur as lockup of a completion interval progressed.

It focuses on the possibility of failure to keep injected waste confined to the subsurface strata located below the upper confining zone, approximatèly 4230 feet of depth. The purpose of the assessment is to provide discussion on potential problems, how these problems will be avoided, and how they will be handled in the unlikely event that they occur. Reservoir Fracturinf/Solids Stora~e The sandstone intervals that will receive fluid and solids injection will initially fracture at a gradient of 0.65 psi/foot of depth. With injection pressures that may reach 1.0 psi/foot, fractures will occur. Maintenance of an open system will require an internal pressure greater than the fracture gradient. '; ( ./ At the central pad, approximately 2000 feet of separation will exist between the oil well casings and the disposal well at the upper disposal interval. At the lower interval, the separations will be approximately 2800 feet or greater. Two source water wells, completed under the pad between 2700 and 3400 feet, will also have a separation of several thousand feet The waste disposal wells will be directed as shown on the spider map of Exhibit 2. No natural faulting exists that is significant enough to provide migration paths for breaching the confining shales. This means that subsurface confinement can only be jeopardized by hydraulic fracturing of the confining zone, recirculation of wastes to the surface through a source water well, fluid migration through an uncemented annulus, or an uncontrolled flow while drilling a new well. These confinement issues are defined as follows. Confininf Zone Inte~rity and Subsurface Waste Confinement Fracturing, Placement of Waste, and Confining Zone Penetration : The injection of solids necessitates fracturing the injection zone and transporting solids between fracture planes created and held apart hydraulically. In the lower disposal zone a SCANNEC; ~JUN j 0 2004 ) -----".. ,l, ') ) conventional fracture is expected to develop with vertical growth restricted by the massive bounding shales. Lateral growth, fracture width, and solids transport will be governed by the fluid leakoff rate; which itself, is a function of interacting rock mechanics, fluid rheology properties, and injection rate. An estimate of how extensive the fracture system will be and how efficient storage will become can be made from the following table which compares other slurry injection disposal projects. In addition to Badami having a smaller slurry injection rate it will have a lower cumulative volume spread over a longer period. The lower zone may eventually lock up and become useless. Further disposal would then have to move up-hole or to ,a new well bore. Disposal Project Maximum Fracture Lateral Dimension (ft) Average Inj. Rate (BPM) Prudhoe DS 4-19 Jasper County Texas Prudhoe CC-2A Badami 2000 1200 800 20 10-15 2.5 1 Should the upper disposal interval be needed, it will be perforated in its lower section ( approximately 5150-5195 feet). Vertical fracturing will also occur but a dendritic -- ~ variation may develop. It is even possible that some rock along the fracture faces will become disaggregated, begin to move, and could further enhance solids storage. It is anticipated that vertical fractures will grow from the lower perforations upward to the c:"i/ ,~hale-~.!!!§!º!l~ªt 4900 feet, and may continue to the shale at 4560 (eet. Based on experience monitoring other North Slope disposal wells, the confining zone should not be fractured. Since maintaining an open fracture system will require an internal pressure greater than the fracture gradient and pore pressure of adjacent reservoir rock, this impacts significantly the following aspects of confinement. Recirculation of Wastes Through Source W ater Wells : Two water source wells will be completed in the saline aquifers above 3400 feet. Very probably they will be drilled as fairly straight holes under the central facilities pad. Alternately they might be drilled directionally away from the disposal well. The source wells will be completed between 2700 - 3400 feet. This means that the vertical separation between them and the upper disposal zone will be 1500 to 1900 feet, ,..... t!~'l\ r~ r'i'l.J'~ r) n! N (I) n, 2 0 0 ,~ ~VIr~n~1'\JE~,,' d í..J ,1 ~',~ ilß - I~ ) ) ler~ [;Ie ~, ') ): and with a lateral separation of 2200 feet or greater. For recirculation to occur, the disposal well would have to fracture into these shallow aquifers and a significant amount of fluid leak off into them. With so much vertical and horizontal separation between completion points, wastes would not be able to streamline to a withdrawal well. The likelihood of recirculation is low because all of the development wells will be drilled prior to initiation of source water withdrawal and; therefore, all solids injection will be effectively completed and fracture growth tenninated before the source wells are functional. Subsequent injection of low solids wastes will not be able to generate a directional transmissibility capable of supporting recirculation. Recirculation potential is almost non-existent. Nevertheless, should this somehow occur, recirculated waste would be confined to the production equipment and again be reinjected. It would also be so diluted that it could not be measured. There would be no environmental or safety risk. Fluid Migration Through an Uncemented Wellbore : There are two concerns associated with upward fluid migration in a poorly cemented annulus. Firstly, should migration extend past the confining zone but then leak off to the overlying aquifers, there is a regulatory problem but no environmental or safety issue since fluids would be confined to the subsurface, and in this area no USDW s exist to be compromised. Secondly and more seriously, should migration reach the surface, while no safety issue can be envisioned, contamination of gravel pad, tundra, or surface water may occur. However, for this to happen, fluids would have to move through the source water sands and not be diverted laterally. Uncontrolled Flow While Drilling a New Well : This risk exists because the fracture system will be at a hydraulic pressure somewhat higher than the fracture gradient, and thus greater than the pore pressure of the surrounding reservoir rock matrix. Should the drill bit encounter a major fracture plane and a high enough pressure exist at the time, flow into the uncased wellbore would result. An extreme case could allow flow to the surface until the fracture pressure was bled down. The risk of intersecting a pressurized fracture system with the drill bit can be effectively managed by drilling the wells closest to the disposal well early in the sequence, when the fracture system is smallest. Flowable liquid volumes would also be smaller and less pressured. Clearly the greatest risk would occur if injection was occuring into the upper zone later in the drilling program and a well course had to pass nearby. Should 8CÞ~NINE[\' JUN ~¡; 0 2004 ) ') progressive events cause increasing concern or injection pressures indicate a change in the disposal program was needed, one alternative would be to minimize injection volumes by maximizing use of annular pumping of mud and other rig liquids. Since most of the mud and clay solids generated while drilling below 5000 feet can be pumped with little or no grinding, half of the rig waste could go down open surface casing annuli at alternate locations if that became desirable. This would, redirect a large volume from the disposal well fracture system. Should flow enter a new wellbore either because of bit penetration or a result of extending fracture growth, the following actions would be taken. 1. The injection well would be shut in and the AOGCC notified of corrective plans. 2. The mud system would be weighted up to 13 #/ gallon ( 0.68 psi/it of depth) or the estimated fracture gradient. 3. If the new well continued to flow, a decision would be made whether to route fluids to tankage or shut in at the wellhead and risk breaking down the cement bonding at the shoe of the surface casing. 4. If the well was shut in and the casing-formation bonding broke down, flow would enter the formations above the confining zone until the pressure bled off. 5. If the well was allowed to flow up the drill string to the surface it would be routed to tankage. Surplus fluid might be weighted-up and reused as additional kill fluid, and/or injection might be started into one of the oil reservoir waterflood wells. 6. As a last resort, flow would be diverted to a surface impoundment area for later disposal and cleanup. SCi-\NNEC JUN 3 0 200,1 ') ) Comparison with Similar Disposal Projects There are five waste disposal, injection projects that can be used as analogies to Badami. Four of them are on the North Slope and one in Canada. Their relevance is as follows. Prudhoe Bay CC-2 Facility: This disposal plant has been in operation five years, grinding up drill cuttings for injection into a single Class II well. Disposal volume is over 8 million barrels as shown in Exhibit 11. With a solids content estimated at 7-8 percent, 625,000 barrels of solids have been injected through an open hole completion at 3500 feet. The facility and well have operated without significant problems and no negative environmental impact. Prudhoe Bay Pad-3 Facility: Since 1979 this facility has injected 9 million barrels of wastes which often included a significant volume of solids. At an estimate of 2 percent, this means 180,000 barrels of solids have been injected. These three Class I wells are completed at 2000 feet, just under the permafrost with 30 feet of separation. They are located about 600 feet from the edge of a development drilling pad with over 40 wellbores. Extensive logging and field testing have not detected any up-hole channeling or other problem. Prudhoe Bay DS4-19 Demonstration: This facility successfully operated from 1995 to the Spring of 1997 to test the feasibility of using grind-inject technology for reserve pit closure on a large scale. Injection rates were high (Average rates 20 times higher than Badami) with solids slurry placed in the same zones as those proposed for Badami. The single injection well performed as planned and no up hole communication was detected until March 17, 1997, after approximately 2,000,000 barrels of slurry was injected. Further details on the breaching incident will be in an ARCa report expected by the end of May, 1997. Endicott Island Disposal Well : At the Endicott oil field (Duck Island Unit) located between Prudhoe and Badami, Class II disposal well2-02/P18 has injected 6 million barrels since 1987. The solids content is less than one percent. The well is located on a drilling island with 55 other wells, all on 15-foot centers at the surface. Waste disposal at a depth of 7000 feet has been confined even though numerous wellbores pass within several hundred feet of the disposal well perforations. \SG/~\.N¡\ì!:;~1 í~JN ",} if) 200 ¡j , ,~ ,- c__. ~. I\! ej ~u ~J' ) ) Lloydminster, Alberta Canada, Celtic Formation Fines Disposal Project: Approved by the Canadian Government, this plant has operated for several years disposing of large volumes of fonnation fines and sand generated by a steam flooded oil reservoir. Injection rate is reportedly high, at a depth of 2000 feet. No other operating details are known. Summary The relationship of these North Slope facilities, and others, to the proposed Badami Project is tabulated in Exhibit 12. Further discussion on waste confinement is included in the Class I Well Permit Application submitted to' the EP A and copied to the Oil and Gas Commission in April, 1996. (Reference is made to sections 3 and 6 within the text.) BPX is confident that mitigation of the problems discussed can be managed at an acceptable cost and the impact of an event can be successfully handled should one occur. It is felt the risk of environmental damage should be viewed as minimal to non-existent. 1:::.'11'.... i\ L"qÜ!L:"[ì" q 'N ~) 0 20 O·r¡ ....'lJvr~ß ~¡'ìJCc._· I.) d 1 (), L,. ) ) Mechanical IntefJrity 20 ACC 25.252 (d) (e) Mechanical integrity will be verified after well construction by testing to 3000 psi as outlined earlier in part 25.252 (c) 6. The casing-tubing annulus pressure will be monitored regularly and reported to the Commission on Injection Report Form 10-406. The tubing-casing annulus volume will vary, and the annulus fluid itself will expand and contract due to temperature changes. At the present time it is hard to specify exactly what high-low annulus pressure limits should be established to trigger a warning and possible shutdown. The exact points will need to be established once a repeatable pattern of fluctuation has been established. This can be determined after several months of performance that would include both the summer and winter ambient temperature swings which affect this operation. ....

AFFA'AS Reply To Attn Of: OW-13? Alison Cooke, Senior Geologist BP Exploration (Alaska) Inc. 900 East Benson Boulevard P.o. Box 196612 Anchorage, Alaska 99519-6612 Subject: EPA Determination Regarding Underground Sources of Drinking Water (USDWs) in the Badami and Northstar Field Areas of the North Slope of Alaska Dear Ms. Cooke: This letter con~irms and augments our telephone conversation of May ~~ 1997, _regardiri~ EPA's determination that there are no USDWs in- the Badami field area. Also, this letter will serve to document EPA's determination that, based upon the information submitted to date, there are aquifers which narrowly meet the regulatory formation water quality threshold for protection as USDWs in the Northstar field area. EPA determined that there are no USDWs at Badami shortly after receiving the supplemental Class I injection well permit information that BPX sent us on June 10, 1996. That submittal contains a detailed set of calculated formation water quality estimates based upon geophysical borehole log data and a realistic range of technical assumptions. We think that this information amply demonstrates that the aquifers beneath the permafrost at Badami are too naturally saline to meet the Underground Injection Control (UIC) program regulatory threshold of 10,000 milligrams per liter (mgjL) of total dissolved solids (TDS), and thus do not qualify for protection as USDWs under the Safe Drinking Water Act. Our first permit application review letter of September 30, 1996, did not mention whether or not EPA agreed with BPX's assertion that there are no USDWs beneath the permafrost at Badami. Subsequent letters also made no mention of the topic. We think that's because those letters focused upon EPA questions and concerns rather than the many areas of agreement with the permit application. The information BPX submitted on June 10, 1996, had convinced us that there are no USDWs in the Badami o Printed on Recycled Paper ,~ /-, ,\\,</ L:' í i I í\1 ~~ n t)nI"L' ".-., ~ field area, as you know from our past conversations. We trust that this letter will serve to document that understanding. In terms of Northstar, our review of the permit application has led us to conclude that there are most likely some USDWs beneath the permafrost. And we also think that they meet the aquifer exemption criteria under 40 CFR 144.6, as described in the BPX permit application. Therefore, we are prepared to process an aquifer exemption at Northstar as part of the Class I injection well permitting process, as BPX has requested. However, a final decision to prepare a draft permit for Northstar cannot be made until the Environmental Impact statement (EIS) on that proposed project has been completed.
