Attachments in Duplicate by • NK-14A Sundry Application Well Type: Producer Current Status: The well is currently suspended. Request: Approval is requested for the P&A of Prudhoe Bay well NK-14A to sidetrack and complete NK-14B CMIT-T x IA Passed to 4000 psi (10/11/2015) MIT-OA Passed to 1200 psi(10/12/15) PPPOT-T Passed to 5000 psi (10/06/2015) PPPOT-IC Passed to 3500 psi (10/06/2015) Well History: NK-14 was drilled and completed in 1996 as a Kuparuk Slant well. The well has suffered from low t w a l productivity and high WC's. While drilling NK-14A two coil tubing sidetracks were drilled in 2006, and alr { wer . The two coil laterals were abandoned by placing a cemen re vrti I (c'°} )41 production liner and`squeezing •••Is of cement below a re aine, an• p acing •• s o cemen 5J5�( ? above the retainer. On 04/30/2007 the well has been classified as suspended. fe kr 1/4 Scope of Work: N° Ofr The sidetrack plan for the NK-14B well includes the following operations. Pre-rig, A plug will be set in an X-nipple at 17,949' MD. A D&D hole finder run will be conducted on slick line to determine the severity and location of the T x IA communication. A tubing punch will run to establish communication above the 4-1/2" x 9-5/8" production packer at 17,925' MD. A cement plug will be circulated into the tubing and IA, which will bring the top of cement to—16,825 MD. Once the cement has setup, the final top of cement will be determined with a drift run followed by an integrity test of the tubing and inner annulus. Next, the 4-1/2" tubing will be jet cut at —13,100' MD. The rig will then move over the well and pull the 4-1/2"tubing and set a whipstock exit—13,000' MD.

Later the cement/retainer was pressure tested to 3,000 psi on May 7th 2007.The top of cement was confirmed by tagging it with eline at 18,089' MD on May 11th 2007. As far about the window exit it appears that whoever made the original NK-14A schematic named the deeper window in correctly.The window depth for NK-14B can be found in the attached schematic.

Foerster Alaska Oil and Gas Conservation Commission 333 West 7th Avenue Anchorage, Alaska 99501 Subject: Niakuk Well NK-14A (PTD # 2060310) Application for Renewal of Existing Suspension (10-403) Dear Ms. Foerster, BP Exploration (Alaska) Inc. completed an AOGCC witnessed suspended well inspection of Niakuk Unit well NK-14A on 05/31/2014 (20 AAC 25.110 (h). This recently submitted suspended well inspection reflects the current condition of the well (reference 20 AAC 25.110 (f)) and supports the request for renewal of suspension. Recent events from this well indicate that this well is mechanically sound. Specific attachments include: • Wellbore diagram illustrating the current configuration of the well • Suspended Well Site Inspection form documenting the pressures and site condition Niakuk unit well NK-14A was suspended on 05/04/2007. It is located on a pad with active wells and/or service wells. The strata through which the well was drilled is neither abnormally geopressured or depleted. The well is secured with a cement retainer above a whipstock and cement above and below the retainer. The well is mechanically sound as proven by a pressure test after the cement was placed. Based on these conditions and the inspection on 05/31/2014 Niakuk unit well NK-14A meets the provisions required in 20 AAC 25.110 (a)(1). Based on this information, BPXA requests approval for renewal of the existing suspension status for this well. Attached is an Application for Sundry Approval (10-403) with a technical justification summarizing the information on the current status and condition of the well (reference 20 AAC 25.110 (a), (b), (e), (h) and (i)). In summary, BPXA believes Niakuk well NK-14A is mechanically sound and secure and meets the requirements for renewal of suspended status. If you have any questions, please call me at 564-4303 or Whitney Pettus/ Kevin Parks at 659-5102. Sincerely, , S Dou laismoski P.E. 9 , BPXA Wells Intervention Manager Attachments Technical Justification 2014 Suspended Well Site Inspection form Wellbore Schematic Cc: Doug Cismoski Pettus/ Parks Ryan Daniel i S Niakuk Well NK-14A (PTD 2060310) Technical Justification for Renewal of Suspended Status August 28, 2015 Well History and Status Niakuk unit well NK-14A (PTD 2060310) was suspended on 05/04/2007 after an unsuccessful sidetrack failed to justify a required rig work over. The well is secured with a cement retainer above a whipstock and cement above and below the retainer. The well is mechanically sound as proven by the passing CMIT TxIA to 3000 psi after the cement was placed. In the current state the well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, is secure, safe and not a threat to public health The strata through which the well was drilled is neither abnormally geo-pressured or depleted. Condition of Wellhead and Surface Location Niakuk unit well NK-14A is located on an active, well maintained pad with clean gravel. The surrounding area is in good condition and there is no discoloration and no sheen on the pad, pits or in nearby water. The well pressure readings are T/I/O= 0/300/150 psi recorded on 05/31/2014 and are stable. Request BPXA requests approval for renewal of the existing suspension status for NK-14A A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to remain as suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area. • • Suspended Well Site Inspection Form Notify AOGCC Inspectors at least 10 days prior to inspection to allow witness 10 Year Well Name: NIAKUK NO 14A Field/Pool: Prudhoe Bay Field/Niakuk Pool Permit#(PTD): 2060310 API Number: 50029226680100 Operator: BP EXPLORATION(ALASKA)INC Date Suspended: 5/4/2007 Surface Location Section 36 Twsp: 12N Range: 15E Nearest active pad or road: L5 Take to Location Digital camera Map showing well location/Aerial photos Brief well history Wellbore diagram showing downhole condition Latest Sundry or Completion report Past Site Visit documentation Site clearance documentation Pressure gauges,fittings,tools Sample containers for fluids on or near pad Condition of Surface Location AOGCC requires: 1)a description of the condition of the surface location, including discoloration, fluids or sheens visible on the ground or in any nearby water, 2) photographs showing the condition of the location surrounding the well General location condition: clean, active pad Pad or location surface level gravel pad Location cleanup needed: none Pits condition: N/A Surrounding area condition: clean Water/fluids on pad: snow melt Discoloration,Sheens on pad,pits or water: none Samples taken: none Access road condition: good Photographs taken(#and description) Yes,wellhouse and flowline area Condition of Wellhead AOGCC requires: 1)a description of the condition of the wellhead,2)well pressure readings,where practicable, 3)photographs showing the wellhead condition Wellhead/tree/valve description,condition: FMC wellhead.

BPXA currently have 59 suspended status wells,of which many would not have *future utility today. My view for the business and from a risk perspective is to leave these wells "as is" until pad level decommissioning. The SU wells on pads with trees are monitored daily and pose minimum risk to our operations. Any wells,that are determined to have a higher risk associated with communication, re-pressurization etc will certainly be given priority for intervention and mitigation. *Additionally,as the business starts to realign from oil to gas over the next 10-15 years we would want to preserve various options (wells and surface locations)for the future.

BP and its working Interest owners are developing some longer term options for"decommissioning" work scope which includes some wells and surface kit.These are screening opportunities only(potential future activities) and still in the very early scoping stage. They are not funded or approved yet,and as such it would be premature for BPXA to comment any further. The Observation well P&A program which I discussed recently with Jim, and the Suspended well renewal applications submitted by Oliver are also separate(discrete and unrelated) activity plans for well stock management and as such have different timelines and rational. We are happy to discuss the Suspended wells further id necessary. If you could use Oliver as the single point of contact for this work that would be much appreciated.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Mehreen Vazir, at 659 -5102. Sincerely, Gerald Murphy BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

Well Data: Status: Shut-In Oil Production Well BHP: 4,237 psi @ 9,000' TVD SS Max Deviation: 103° @ 19,352' MD Min ID: 3.8" @ 17,696' MD (4-1/2" HES `XN' Nipple) Last TD Tag: 19,660' MD on 5/4/2006 (CTU Sidetrack) Last Downhole Ops: On 5/3/06 a 3-3/8" IBP set in 4-1/2" tubing @ 17,879' -17,890' MD (Center at 17,885' MD) H2S: 55ppm 10/4/2005 AnnComm: Poor Tubing (TxIA communication) Background: The parent well, NK-14, was a low rate oil producing well which was shut-in prior to the CTD sidetrack due to low productivity. On 3/27/06 a MIT on the IA failed. On 4/2/06 a tubing caliper log was run, details are presented lafier in the program. A CMIT TxIA to 3000 psi was peformed 4/4/06, the tests were inconclusive. The caliper log determined that the tubing would need to be replaced, requiring a RWO. Rather than replace the tubing via a RWO, it was decided to sidetrack this well to determine whether or not the increased oil production would justify the added expense of a RWO, required to replace production tubing. The sidetracking venture proved to be unsuccessful, and as a result the RWO was suspended and the well is currently SI. On May 3, 2006 BP applied for temporary shutdown of drilling operations on NK-14A under regulation 20 AAC 25.072. The NK-14A drilling results were disappointing because the shallow target (best quality sand) was swept and the deeper targeted sands were poorly developed or absent. There was insufficient pay to justify a completion; in addition an expensive RWO was needed in order to flow the well. Over 18,000' of tubing needed to be pulled, with the possibility of also running a 7,000' scab liner. Neither BP, nor the partners felt that the reserves in the well would support a RWO plus completion costs. On May 4, 2006, the AOGCC commission granted the operation shutdown of NK-14A. Current Well Conditions: A mechanical whipstock was set at 18,216.5' MD (top) (bottom at 18,223' MD) correlating to the Memory Jewelry Log dated 20-April-2006, a window was drilled from 18,220' - 18,226' MD with a 4-1/8" drill bit on coil tubing. Drilling operations proceeded with a horizontal lateral being drilled to 20,541' MD with 9.0 ppg drilling fluid. The well was open hole sidetracked from 19,140' - 19,160' MD when it was determined that the 2FS sand was not present. This operation in effect has created a "dual lateral" wellbore, both of which are openhole. A infectivity test was performed April 17, 2006 using 9.4 ppg brine. The following table illustrates the injection rates at their respective pressures. Table 1 Infectivity Test Results re 0.58 320 1.07 392 1.6 460 2.05 494 2.53 505 3.1 546 Prior to suspending drilling operations a Baker 3-3/8" Retrievable IBP was set in the tubing at 17,879' MD (center of the first joint above "X" nipple). The tubing in the well, from 4,100' -17,879' MD, was then displaced to 9.0 ppg KCUNaCL brine. Finally, the well was freeze protected with diesel from 4,100' MD to surface. Before moving off the well the CTD rig set an IBP at 17,879' MD on 5/3/2006 and a successful CMIT-TxIA pressure test was performed to 1,000 psi. 2 A caliper log was run on the tubing April 2, 2006. shape. There are multiple holes recorded in th (11,000' - 15,300'). Caution should be exercised The damage to the tubing appears to be in the f corrosion, and isolated pitting. The caliper survey reference. The 4-1/2" Tubing is in very poor e tubing between GLM #3 and #2 when tripping through this section. orm of lines of corrosion, general from April 2, 2006 is attached for Objective: The intent of this well intervention is to plug NK-14A per Alaska State Regulation 20 ACC 25.112 and to ensure that future utility of the wellbore is maintained. The plugging of the well will ensure that all hydrocarbons and freshwater are confined to their respective indigenous strata and will prevent migration of fluid into other strata or to the surface. The wellbore will also be preserved such that a future sidetrack is possible. Procedure: 1. Rig-up coil tubing unit #5 with 18,600' of HS80 1-3/4" tapered coiled tubing string. 2. Run in hole and pull 3-3/8" retrievable IBP from 4-1/2" tubing which is at 17,879'MD. 3. Document pressures on the tubing, IA, and OA. NOTE: Last bottom hole pressure on 1/18/06 was 4304 psi at 9200' SSTVD. Expect wellhead pressure to be 415 psi (based on 9.0 ppg brine from 4100' MD to TD and diesel from 4100' MD to surface). 4. Ensure that the IA is fluid packed. 5. RIH with coil to 4,500' MD circulate tubing with 80 barrels of 9.0 ppg NaCI brine. This should result in ~0 WHP. Freeze point of brine is 19°F. 6. Perform a short formation infectivity test. 7. Rig up coil tubing unit with Schlumberger Memory GR/CCL and RIH. Log well for depth correlation. Correlate to Schlumberger Injection Profile w/Warmback/Jewel Log dated October 6, 1997. 8. Pick up the Baker Inflatable Cement Retainer with Spotting Valve and set per Baker specifications such that top of assembly is at 18,198' MD; avoiding collars. Reference log for depth control will be Memory GR/CCL. Do not run Cement Retainer with Spotting Valve into whipstock at 18,216' MD. Mix 8 pumpable barrels 15.8ppg Class G cement. • NOTE: Cement volume is based on 5 bbls of cement in 4-1/8" openhole below retainer, and 3 bbls of cement in 7" liner above the cement retainer Catch a sample of the cement for QC testing. ', , a ~ • Ensure all gas is out of the system. Do not proceed with squeeze unless the tubing is liquid packed and gas free. 9. Apply tension to tubing string per Baker specifications to open spotting valve. 10. Line out cementers to the CT. Pump the following down the coil: 10 bbls spacer water 5 bbls 15.8 ppg Class G cement 11.Open the choke on the backside (tubing x CT annulus). 12. With 3 bbls of cement left in the coil, un-sting coil from the cement retainer per Baker specifications and lay in the remaining 3 bbls of cement on top of the retainer, taking 1:1 returns at surface. PUH to safety 17,980' MD. With the retainer at 18,198' the top of the cement assuming 8 bbls cement (worst-case- scenario) should be approximately 17,983', this would give 215' of cement on top of the retainer. 13. Begin pumping biozan down the CT for clean out. Make a couple of passes from the cement top at 18,115' MD (3 bbls on top of retainer) to safety. Jet uphole at 80% running speed and max CT pressures, washing all jewelry thoroughly noting GLM's and TRSSV. NOTE: Tubing will need to be replaced prior to producing well in the future. Clean-out is to ensure that the TRSSV and the nipple profiles are clean and in operable condition. 14. Freeze protect tubing and IA. Post CTU Cement Plug 15. After 5 days WOC, MIT-T to 3000 psi. Note: IA pressure should track tubing pressure. 16. If MIT-T passes rig up slickline and drift well to TOC at approximately 18,115' MD.

Well Prudhoe Bay Unit NK-14A Prudhoe Bay Field, Niakuk Oil Pool AOGCC Permits 206-031 Requested Action: BP Exploration (Alaska) Inc. (BPXA) proposes to plug the existing well for potential future sidetracking. Recommendation: I recommend approval of BPXA's proposed actions Discussion: Well NK-14 was a poor producing well that BPXA sidetracked in 2006 to create the NK- 14A wellbore. BPXA and partners decided not to complete the sidetrack because one of the two sand lobes that were targeted by the sidetrack was already swept and the other lacked sufficient pay. The well has been in AOGCC approved operational shutdown status since May 4, 2006. Since the original wellbore was plugged prior to the sidetracking operation and the sidetrack was not completed, and is possibly inaccessible due to the wellbore collapsing, the well has no current usefulness. Setting a plug to isolate the sidetrack from the remainder of the wellbore so that the well could possibly be sidetracked again in the future is a prudent operational decision. Conclusion: This well is currently providing no benefit to field operations. The best use of this well is to prepare it for a possible future sidetrack. D.S.

The NK-14A well results were disappointing because the shallow target (best quality sand) was swept i" and the deeper target sands were poorly developed or absent. There was insufficient pay to justify a completion; in addition an expensive RWO in order to flow the well was needed. Over 18,000' of tubing needed to be pulled, with the possibility of also running a 7000' scab liner. Neither BP, nor the partners felt that the reserves in the j well would support a RWO plus completion costs. The plan forward is to move the rig while the subsurface team regroups and evaluates options for NK-14. At this time the well remains a candidate for redrilling. The proposed condition of the wellbore is as follows: The drilling fluid in the tubing will be displaced to 9.0 ppg brine with freeze protect fluid down to 5000'. An IBP will be set in the tubing tail at 17930' to aid in pressure monitoring/testing of the IA. 5 I~..w~ ~ wK- ci..~! rl r o ~. 3 vwwr ~-~, s Sean McLaughlin CTD Engineer 564-4387 CC: Well File Sondra Stewman/Terrie Hubble ~ ~,- S .

Re: The Application of BP Exploration (Alaska) Inc. )Conservation Order No. 329 to present testimony for classification of a new ) oil pool and to prescribe pool rules for development )Prudhoe Bay Field of the Niakuk Oil Pool within the Prudhoe Bay Field. )Niakuk Oil Pool January 11, 1994 IT APPEARING THAT 1. By letter dated September 22, 1993, BP Exploration (Alaska) Inc. requested a public hearing to present testimony for establishing pool rules for development and operations in the Niakuk reservoir. 2. Notice of public hearing to be held on October 28, 1993 was published in the Anchorage Daily News on September 28, 1993. 3. A hearing concealing the matter of the applicant's request was convened in conformance with 20 AAC 25.540 at the Commission's offices, 3001 Porcupine Dr. Anchorage, Alaska 99501 at 9:00 am October 28, 1993. 4. ARCO Alaska, Inc. requested the areal limits of the pool be expanded beyond the limits proposed by BP Exploration (Alaska) Inc. (see addendum decision). 5. The hearing was reconvened on November 15, 1993 at 9:00 atn. 6. Testimony was offered by BP Exploration (Alaska) Inc., ARCO Alaska, Inc., Exxon Company, U.S.A. and the Alaska Department of Natural Resources, Division of Oil and Gas. 7. The hearing record was closed December 3, 1993. Findings: 1. The area planned for development by BP Exploration (Alaska) Inc. and described as the Niakuk reservoir underlies portions of ADL leases 34625, 34630, 34634, and 34635. BP Exploration (Alaska) Inc. is operator and I00% working interest owner of these leases. The State of Alaska is the lessor and 100% owner of the royalty interests. 2. ARCO Alaska, Inc. requested that the pool rules area include portions of ADL 34626 and ADL 34629, to which BP Exploration (Alaska) Inc. objected. The Commssion's decision concerning ARCO Alaska, Ine.'s request is an addendum to this order. 3. The Niakuk 5 and Niakuk 6 wells, drilled on ADL 34635, tested hydrocarbon production from the Kuparuk River Formation at oil rates between 1800 and 4800 BO/D. ~}. The Niakuk 1 and lA wells, drilled on ADL 34630, encountered measurable hydrocarbon sahiration in the Kuparuk River Formation, but the wells were not tested. 5. The Niakuk 6 well contains the entire stratigraphic interval for the Kuparuk River Formation, which 1 of 10 2/27/2006 2:25 PM STATE OF ALASKA http://www.state.ak.us/local/akpages/ADMIN/ogc/orders/co/co300_... occurs between 951 feet TVD subsea and 9842 feet TVD subsea. 6. The Prudhoe Bay Unit encompasses the BP Exploration (Alaska) Inc. leases proposed for development. 7. Lateral heterogeneity and abrupt fades change characterize the Kuparuk River Formation in the area plamle~d for development by BP Exploration (Alaska) Inc. 8. Numerous moderate displacement normal faults cut the Niakuk reservoir. 9. The Niakuk reservoir contains two elongated, oil-bearing segments that do not appear to be in hydraulic communication. Normal faults bound the two segments on the north and south. 10. The western segment (Segment 1) contains approximately 545 acres. An inferred depositional pinch out marks the eastern limit of Segment 1. The western limit of the oil accumulation is uncertain. 11. The eastern segment (Segment 2) contains approximately 1,310 acres. Structural dip and the oil-water contact controls the eastern limit of Segment 2. A depositional pinch out of the reservoir marks the western limit of Segment 2. 12. The following are rock properties for the Kuparuk River Formation determined by analysis of log, core and test data from the Niakuk 1, Niakuk lA, Niakuk 2, Niakuk 2A, Niakuk 5, and Niakuk 6 wells. Porosity Permeability Net/Gross Oil Seb Went Saturation 1 Zone 3 24.4% 6-1250 and 1.0 66% Zone 4 15.2% 6-1250 and .95 75% Segment 2 Zone D 19.5% 1-1169 md. .87 67% Zone F 23.0% 1-3008 and .98 79% 2 of 10 2!27/2006 2:25 PM STATE OF ALASKA http://www.state.ak.us/locaUakpages/ADMIN/ogc/orders/co%o300 ... 13. Fluid roe ~ ~ ~ ~ p p rties are based on reservoir fluid samples from Niakuk 5 m Segment ~. Initial reservoir pressure is 4461 psia at 8900' TVD subsea. Bubble point pressure is estimated at 3835 psia. Reservoir temperature is 181 oF. Oil gravity measures 24.9o API, viscosity 1.4 centipoise~ and oil formation volume factor 1.31 RB/STB at bubble point pressure. 14. Agas-oil-contact (GOC) has not been identified in the Niakuk wells. 15. The oil-water contact (OWC) is estimated at 9244' TVD subsea in Segment 1 and at 9520' TVD subsea in Segment 2. 16. Estimated original oil in place (OOIP) for the Niakuk reservoir is 137.4 MMSTB (56.1 MMSTB in Segment 1 and 81.3 MMSTB in Segment 2) and original gas in place (OGIP) is 90.9 BSCF. 17. The Niakuk reservoir will be developed from a drill site constructed at Heald Point. Well testing facilities will be installed at the Niakuk drill site. 18. The operator proposes to set conductor casing to 80 feet below pad level in compliance with 20 AAC 25.030. 19. The operator proposes to set surface casing no deeper than 5000 feet TVD in compliance with 20 AAC 25.030. 20. Permafrost is present in the Heald Point area to a depth of 1900 feet. 21. No hydrocarbons or abnormal pressures have been encountered above 5000' TVD subsea in the Niakuk wells drilled to date. 22. The operator proposes to install fail-safe, automatic surface and subsurface safety valves (SSV's & SSSV's) in all wells capable of unassisted flow of hydrocarbons. 23. The Commission may require SSV's and SSSV's in wells capable of unassisted flow of hydrocarbons in areas deemed appropriate under 20 AAC 25.265. 24. In certain cases, the SSSV's must be removed temporarily to allow passage of certain eduipment and performance of well maintenance. 25. A total of 9 producers and 5 injectors are currently plamled for the Niakuk reservoir. 26. The operator proposes to commingle production from Niakuk wells with production fromother oil pools for processing at the Lisburne Production Center (LPC). 27. The Cotnrnission has previously approved surface commingling of Lisburne, Pt. McIntyre, Stump Island and West Beach production for processing through the LPC. 28. The operator testified that commingling production and utilizing existing production facilities extends field life and reduces capital investments and per barrel operating costs for small hydrocarbon accumulations. 29. The operator estimates that 100 million additional barrels of oil will be recovered by allowing commingled production from Niakuk, Pt. McIntyre, Stump Island, West Beach and Lisburne reservoirs. 3 of 10 2/27/2006 2:25 PM STATE OF ALASKA http://wwwstate.ak.us/local/akpages/ADMIN/ogc/orders/co/co300_... • 30. BP has reached agreement with the Lisburne working interest owners to commingle Niakuk production with production from the Lisburne, Pt. McIntyre, West Beach and other fields within the area defined as the "Greater Pt. Mchltyre Area" (GPMA). 31. Monthly well tests will be used to allocate production to each producing well. The operator proposes to test each well twice monthly, conditions permitting. Optimum well test stabilization and duration times will vary from well to well and may change with time. 32. NGL's will be allocated based on gas volume produced and computer simulated process yields. 33. The Lisburne Data Gathering System (LDGS) will be utilized to monitor the flowing status, pressures and temperatures of Niakuk wells. 34. Process capacities at LPC will be increased from 100 to 135 MB/D oil and from 25 to 200 MB/D water. Gas processing capacity is expected to remain at 460 MMSCF/D. Facility expansions are expected to be completed in 4th Quarter 1994. 35. hlitial share of process capacity at the LPC among commingled pools will be based on producing gas-oil ratios. 36. The operator proposes to determine reservoir pressure with initial and periodic surveys on each well using a datum of 9200' TVD subsea. 37. The operator will use production logs, including flow meters, temperature and other diagnostic tools, to study reservoir performance. 38. Produced gas allocated to Niakuk, less gas sold or used for lease purposes, will be injected into the Lisburne oil pool. 39. The operator proposes to initiate waterflooding within one year after commencement of regular production. 40. The operator does not expect to create moveable gas saturations before commencement of waterflood. 41. Primary recovery mechanism for the Niakuk reservoir is solution gas drive. Model studies indicate expected recovery for primary depletion is 4% of OOIP. 42. Estimated recovery with waterflooding is 40% of OOIP. 43. The operator's model indicates that delaying waterflood one year after regular production will not harm ultimate recovery. 44. The operator proposes initial waterflood injection rates greater than voidage rate to provide pressure support and increase reservoir pressure above bubble point pressure. 45. Initially, produced water will be injected in the LPC Cretaceous disposal wells. 46. Regular production is expected to start in April 1994, at approximately 15 MB/D and rise to 23 MB/D in April 1995. 47. Offtake rate and waterflood sensitivity studies indicate no impact on ultimate recovery using rates 4 of 10 2/27/2006 2:25 PM STATE OF ALASKA http://wwwstate.ak.us/locaUakpages/ADMIN/ogc/orders/co/co300_... • from 15-20 MB/D and starting waterflood within one year of initial production. 48. BP Exploration will operate the Niakuk reservoir, conducting facility construction, drilling, well operations and reservoir management. ARCO Alaska, Inc., as operator of the LPC, will provide well testing and production allocation support functions. Conclusions 1. Commercially exploitable hydrocarbons are present within two separate segments in an area planned for development by the operator and described as the Niakuk reservoir. 2. Pool rules for the development of the Niakuk reservoir are appropriate at this time. 3. An integration of interests for the area contemplated for development by the operator exists between the working interest owner and royalty owner. 4. The vertical limits of the Niakuk reservoir may be defined in the Niakuk 6 well which appears to be a typical and representative well. 5. Optimum well spacing will depend on reservoir properties and sweep efficiency. 6. Statewide well spacing does not allow suff dent latitude in the selection of well locations because of the elongate shape, small size, and structural and stratigraphic complexity of the reservoir. 7. Other than establishing setting depths, the operator is not requesting variance from statewide casing and cementing requirements. 8. The Heald Point drillsite is an onshore location. 9. Because of the proximity of the Heald Point drillsite to the Beaufort Sea, the use of fail-safe, automatic surface and subsurface safety valves are appropriate and may contribute to safe production operations 10. Surface commingling of Niakuk production with Lisburne, Pt. McIntyre, Stomp Island and West Beach production will increase ultimate recovery, will not cause waste nor jeopardize correlative rights. 11. Well tests are an appropriate means to allocate produced fluids back to the originating field for revenue and reservoir management purposes. 12. Periodic review of production allocation procedures is appropriate to evaluate techniques and to revise procedures if warranted. 13. Initial management of process capacity at the LPC using producing GOR is appropriate, however, in the event of capacity proration each producing field should be equitably handled. 14. Appropriate reservoir surveillance data will be obtained to plan and optimize primary development, secondary recovery, and reservoir management plans. 15. Exception to gas-oil-ratios is not appropriate at this time because produced gas is not being returned to the reservoir and no additional recovery proj ect is scheduled for the first year of regular production. 5 of 10 2/27/2006 2:25 PM STATE OF ALASKA http://www.state.ak.us/local/akpages/ADMIN/ogc/orders/co/co300_... 16. An exception to 20 AAC 2 .240 maybe considered in conjunction with waterflood or if production at more than twice original solution GOR is necessary for acquisition of pool performance data. 17. Waterflood will enhance oil recovery from the Niakuk reservoir. 18. Water injection may not commence until 20 AAC 25.40? and .460 are satisfied. 19. Subject to the rules below and statewide requirements, production from the Niakuk reservoir may occur in a manner that will protect freshwater, prevent waste, protect correlative rights, and provide for the maximum ultimate recovery of oil and gas that is prudent. NOW, THEREFORE, IT IS ORDERED THAT the plan of development submitted by BP Exploration (Alaska) Inc. is approved, subject to rules hereinafter set forth and state-wide requirements under 20 AAC 25, for the following affected area. Umiat Meridian T12N R15E Section 23 S/2 Section 24 SW/4 Section 25 All Section 26 All Section 36 NE/4 T12N Rlw Section 28 All Section 29 All Section 30 All Section 31 N/2 Section 32 N/2 Rule 1 Field and Pool Name The field is the Prudhoe Bay Field.

Rule 6 Surface Commingling and Common Facilities 7 of 10 2/27/2006 2:25 PM STATE OF ALASKA http://www.state. ak.us/local/akpages/ADMIN/ogc/orders/co/co3 00_... I • • a. Production from the Niakuk oil pool may be conuningled on the surface with production from other pools for processing at the LPC prior to custody transfer. b. Production from each well will be determined by the following well test allocation methodology. Allocation data and well test data will be supplied to the Commission monthly in both computer file and report formats. i. Conduct well tests to determine production rates for each well. ii. Calculate each well's theoretical monthly production (TMP) based on well test rate(s) and actual time on production. iii. Sum the TMP volume for all wells in all pools. iv.
