History and current status: • 1995: Original Completion • 2005: Rotary sidetrack, NK-38A • 2009: RWO to mitigate IAxOA communication (new upper 9-5/8" casing). OA cemented to surface NK-38A does not have any existing value left. Proposed plan: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around August 15st, 2016. E-line unit will attempt to drift and set CTD whipstock. Nordic 2 will mill a 3.80" window in the 4-1/2" liner and drill a Niakuk Ivishak well to -17,265' MD. The lateral will be completed with a 3-1/2" x 2-7/8" 13Cr-80 liner which will be cemented and perforated. This Sundry covers plugging the existing NK-38A perforations via the NK-38B liner cement job or liner top packer set post-rig (alternate plug placement per 20 AAC 25.112(i)) and via posi-set plug. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference. � SCJ^�4' (rad) �i '� _ ` 61121 11-4 Ifr41-"- /41 rileA btuve P I' 7-17 114 vv-e a (foo, ff; i fm) Ved re fr ry,) ter r, d4a� ihe /'o 37/146 • • • CTD Drill and Complete NK-38B program: Rig Start Date: August 15st, 2016 Pre-Rig Work(scheduled to begin June 1st, 2016) Pull LGLV.

Sundry Application Plug for Re-drill Wells Work Flow This process is used to identify wells that are suspended for a very short time prior to being re- drilled. Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box Geologist tl . in the upper left corner of Form 10-403 is checked. If the "Abandon" or „ "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist work) the initial reviewer will cross out that erroneous entry and initial then i it on both copies of the Form 10-403 (AOGCC's and operator's copies). v Instead, check the "Suspended"box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill" box, she will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, she will check the Stat Tech History tab in RBDMS for the"Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, she will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding"user query in RBDMS to ensure that all of the Plug for Redrill wells have been Geologist handled properly. At this same time, they will also review the list of suspended wells for accuracy. • • BP Exploration (Alaska) Inc.

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.

Heald Point drill pad at Prudhoe Bay has been used to access oil from several oil pools, including Raven. The BIA told BP to suspend Raven production in late December due to a court ruling.

Federal claims court judge Nancy Firestone ruled this fall that the Oenga family is owed millions in unpaid rent because the BIA improperly allowed BP to tap three offshore oil deposits from the family's allotment on the northern edge of the vast Prudhoe oil field. The BIA approved BP's expanded use of the allotment without the family's consent, in violation of the family's contract with BP, Firestone said in her 168 - page ruling on Nov. 22. A week ago, the BIA told BP to shut down production from Prudhoe's Raven unit, the only one of the three disputed offshore deposits that BP was still accessing from the allotment. BP shut down Raven, which produced about 25,000 barrels of oil in November, on Friday. BP is still legally tapping the Niakuk field from the allotment. The battle over unpaid rent and unauthorized land use involves a nondescript finger of land called Heald Point that extends into the Beaufort Sea. The Oenga family acquired its 40 -acre allotment at Heald Point decades ago for subsistence hunting. But in 1989, the family patriarch, Andrew Oenga, signed a contract with BP allowing the oil giant to use Heald Point as a right of way. Years later, believing that BP was giving the family annual rent payments much lower than the land's true value, eight of Oenga's heirs -- including two children, his grandchildren and great - grandchildren -- sued the BIA in 2005. The family said it had to go to court because it was unable to persuade the agency, which is in charge of collecting the family's rent from BP, to take action on its behalf. In an eight -day Lower 48 trial last July, the agency and the oil giant defended themselves against the Oengas' claims. BP argued in court filings that no additional money was owed to the family. The BIA argued that the family's claims for unpaid rent were exorbitant. • The judge ruled for the family, saying the BIA owes it roughly $5 million for the unauthorized use of the land, but she also said that BP is paying too little for the land it is authorized to use. The judge is still taking briefings on the exact amount owed but it will be far below the $200 million the Oengas originally sought. BP Alaska spokesman Steve Rinehart said Tuesday the company is evaluating its best path forward on a potential appeal. He emphasized that Raven represented a fraction of Prudhoe's output. BIA's acting director in Alaska did not return a call for comment on Tuesday. In a written statement late week, Oenga family member Tony Delia said the family is willing to end the matter. "Earlier this month we made BP a fair offer -- pay what is owed and we will renegotiate the lease so they can use our land to produce from Raven and wherever else they want to drill. They haven't responded," he said. According to a written statement from the family's attorney, Ray Givens, the total amount owed the family is $15 million. That figure includes the Oenga family's calculation of how much additional money it is owed in unpaid rent for BP's authorized use of the land, which was not part of the this lawsuit. In her ruling, Firestone said evidence from the trial showed that BP withheld critical information about Heald Point's strategic value for oil development when it negotiated a contract with the family to use the land. "Clearly, (BP) did not wish to share much with the plaintiffs," she wrote. Find Elizabeth Bluemink online at adn.com/contact /ebluemink or call 257-4317.

Circulate out freeze protection fluid and circulate well to clean seawater through the cut. 2. Pull and LD 4-1/2", 12.6#, L-80 tubing string down to the cut. 3. Run 9-5/8" casing scraper to the tubing stub. 4. RU E-line, run USIT in 9-5/8" casing from the tubing stub to surface in cement and corrosion detection mode. 5. Set retrievable bridge plug 100' below the top of cement and pressure test to 3,500 psi for 10 min. 6. Cut and Pull 9-5/8" 47#, NT-80S surface casing. Note: Pipe rams will not be changed to 9-S/a" as the well has two tested barriers (FasDrill plug and RBP) to the reservoir. 7. Run and fully cement new 9-5/8" L-80 47# Hydril 563 casing with ECP, ES Cementer and casing patch to surface. 8. Drill out the ES cementer assembly. 9. Pressure test 9-5/8" casing to 3,500psi for 30 minutes. 10. Retrieve bridge plug. • • 11. Drill out FasDrill and push it to the bottom of the wellbore. 12. Run 4-'/2" 12.6#, 13Cr-80 completion with Baker S-3 packer with I-wire. 13. Displace the IA to packer fluid and set the packer. 14. Test tubing and IA to 3500 psi. Freeze protect to 2000' TVD. 15.

(BPXA) to produce and inject from the Ivishak interval from the NK-38A and NK-65A Wells. This approval is valid until April 1,2006 to allow production and injection during the Raven Participating Area (RP A) application process. On October 27,2005, the Division approved tract operations for BPXA to commingle and conduct production from the Sag River and Kuparuk intervals in the NK-43 Well. This approval is valid for 180 days from the date test production from the Sag River interval in the NK-43 wellbore flows into the Lisburne Production Center. Test production commenced on February 3,2006, and thus this approval extends through August 3, 2006. On· February 8, 2006, BPXA submitted an application with the Division to approve formation of the RPA. The proposed RPA will encompass the Ivishak and Sag River Formations in this area, including production from the NK-38A and NK-43 Wells. BPXA has also filed an application with the AOGCC for pool rules for a Raven OilPool. To allow continued production and injection for the NK-38A, NK-43 and NK-65A Wells while the Division completes its review and action on the RP A, we request that the above referenced tract operations for each of the wells be extended until September I, 2006, or the date the RPA becomes effective, whichever occurs first. Please contact Gary Gustafson at 564-5304 if you should have any questions. Thank you. Sincerely yours, ~ ~an~J GPB Manager or .. . .

Within a few days, the GOR of well NK-38A is anticipated to exceed these limits. NK-38A began production testing on March 30, 2005. The well produces within the Ivishak formation within the Niakuk area. Pool rules have not been established for this formation. BPXA wishes to continue production until July 31, 2005 to gain information to help determine the optimum reservoir management program for the pool, including the feasibility of water injection. Based upon preliminary modeling work, BPXA does not expect negative impact to ultimate recovery as a result of production at higher GORs during the requested test period. 20 MC 25.240(b)(3) allows the Commission to waive the GOR limitation if acquisition of pool performance data is necessary to determine an optimum reservoir management program. Waiver of the GOR during the proposed test period will not promote waste of the resource and is needed to help determine an optimum development plan for the r se oir. Therefore, the Commission waives requirements of 20 MC 25.240(a u . July 31, 2005. -' bp . . BP Exploration (Alaska) Inc. 900 East Benson Boulevard PO.

'i). r'".. !i'nns. C!3ffi11\\$s\m::\ Mas\(~ yi\ ~ u.... u Anchorage Dear Commissioners: In accordance with 20 AAC 25.240(b)(3), BP Exploration (Alaska) Inc. (BPXA), operator of the Prudhoe Bay Unit (PBU), applies to waive the Gas-Oil Ratio (GOR) limitations for the NK-38A Well in the Niakuk area. This waiver is needed to acquire the pool performance data required to determine an optimum reservoir management program. NK-38A Well production testing began March 30, 2005. Recent reservoir trends indicate that within a few days the NK-38A Well is expected to exceed the established GOR. BPXA wishes to continue production testing for this Ivishak well to obtain enough pool performance data to help determine an optimum reservoir management program. Therefore, effective immediately, we request a waiver on the GOR limitation for this well until July 31,2005. During the requested waiver period, BPXA will perform laboratory shrinkage tests to allow the well tests to be corrected and to establish initial tract GOR. We will also perform reservoir surveillance to determine completion efficiency. These data will be used to develop an optimum reservoir management program, including water injection feasibility. The NK-38A Well will be tested regularly during this timeframe to verify reservoir performance. Based upon our preliminary modeling work, we do not expect that continued well production at a higher GOR during the waiver period will affect ultimate recovery. Should you have any questions related to this request, don't hesitate to contact Gary Gustafson at 564-5304. Sincerely Yours, 'Vv~W~ Mark Weggeland GPMA Manager /' 1 .

McIntyre Area Manager BP Exploration Alaska, Inc. P.O. Box 196612 Anchorage, AK 99619-6612 Re: Waiver of Gas-Oil Ratio Limitations for Niakuk well NK-38A Dear Mr. Weggeland: By letter dated April 12, 2005 you requested waiver of the requirements of 20 MC 25.240(a) which limits producing gas-oil ratio ("GOR") within an oil well to no more than twice the original solution GOR of the crude. Within a few days, the GOR of well NK-38A is anticipated to exceed these limits. NK-38A began production testing on March 30,2005. The well produces within the Ivishak formation within the Niakuk area. Pool rules have not been established for this formation. BPXA wishes to continue production until July 31, 2005 to gain information to help determine the optimum reservoir management program for the pool, including the feasibility of water injection. Based upon preliminary modeling work, BPXA does not expect negative impact to ultimate recovery as a result of production at higher GORs during the requested test period. 20 MC 25.240(b)(3) allows the Commission to waive the GOR limitation if acquisition of pool performance data is necessary to determine an optimum reservoir management program. Waiver of the GOR during the proposed test period will not promote waste of the resource and is needed to help determine an optimum development plan for the r se oir. Therefore, the Commission waives requirements of 20 MC 25.240( u . July 31, 2005. ~RPR.12.2005 8: 52RM . NO. 875 P.2/3 , . bp . o , ElP ExploratIon (Alaska) 1M. 900 East Ele~501') BOlllQl/ard P.O.

(BPXA), operator of the Prudhoe Bay Unit (PBU)J applies to waive the Gas-Oil Ratio (GaR) limitations for the NK-38A Well in the Niákuk area. This waiver is needed to acquire the pool performance data required to determine an optimum reservoir management program. NK-38A Well production testing began March 30, 2005. Recent reservoir trends indicate that within a few days the NK-38A Well is expected to exceed the established GaR. BPXA wishes to continue production testing for this Ivishak well to obtain enough pool performance data to help determine an optimum reservoir management program. Therefore, effective immediately, we request a waiver on the GOR limitation for this well until July 31 , 2005. During the requested waiver period, BPXA will petiorm IÇlboratory shrInkage¡ tests to allow the well tests to be corrected and to establish initial tract GaR. We will also perform reservoir surveillance to determine completion efficiency. These data will be used to develop an optimum reservoir management program, including water injection feasibility. The NK-38A Well will be tested regularly during this timeframe to verify reservoir performance. Based upon our preliminary modeling work, we do not expect that continued well production at a higher GOR during the waiver period will affect ultimate recovery. Should you have any questions related to this request, don't hesitate to contact Gary Gustafson at 564-5304. Sincerely Yours, ~W Mark Weggeland GPMA Manager 1 RPR.12.2005 8: 53RM . , i .~ , ..

"Leak Off and Formation Integrity Tests" SOP Job 5: Drill 8-1/2" Intermediate Hole Hazards and Contingencies ~ The intermediate section will kick off in the Ugnu formation and TD at the top of Sag River. There are no fault crossings in the intermediate section. Lost circulation is not anticipated. Follow the lost circulation decision tree should LC become problematic. As planned, the well bore will drill over an east/west-trending fault. This fault is well below the planned well path and risks of cutting this fault are extremely low. ~ Cuttings gas and gas cut mud has been encountered within the West Sak interval at Niakuk. This interval does not contain substantial amounts of hydrocarbons and will not require cement isolation. The most recent Niakuk drilling history has shown this interval to be drilled with mud weights ranging from 9.1 to 9.3 ppg without any problems, nevertheless monitor for any signs of overpressure. ~ The NK-38A well path will drill full sections of the Tuffs, HRl, and Kingak shales, and each of these formations have been troublesome in the Niakuk area. The Tuffs is typically slow and erratic drilling, which can wipe out a PDC bit if proper drilling parameters are not maintained. The HRl and Kingak on the other hand, have shown severe hole instability problems. Follow all shale drilling practices to limit high ECD's, and maintain proper mud weights and shale stabilizers in the drilling fluid. NK-38A will start at 64° inclination and drop to 40° prior to reaching the HRl. 10.9 ppg mud weight will be adequate to maintain wellbore stability though the Kingak shale to interval TD. Follow all shale drilling practices to minimize potential problems. ~ No Kuparuk is expected. However, there may be a thin (-20) Kuparuk interval present above the Kingak that is below seismic resolution. The Kuparuk is expected to be oil bearing, if present. The Kingak top will be deeper to allow for the possible Kuparuk thickness.

"Running and Cementing a Drilling Liner" RP Job 7: Drill 6-1/8" Pilot and Production Hole Hazards and Contingencies ~ The pilot hole is planned to drill into the Kavik far enough to see TKVK on LWD. Avoid drilling into the Lisburne formation. Prognosed TD is at -10,081 TVDss, leaving -42' TVD of undrilled Kavik. ~ The target and polygon for the horizontal section may change based on the results of the LWD. ~ Three faults are prognosed for the horizontal section: · Fault #1 dies upward and may not be present in the Upper Ivishak where the wellbore is located. · Fault # 2 is the critical fault. Cross this fault and enter the north fault block between the TZ2A1and TKVK interval. Err to the high side when crossing this fault to avoid drilling into the Kavik formation. Use logs/cuttings and geo-steer to remain in zone. There is a small possibility that the polygon may have to be enlarged to accommodate unexpected dip variations. . Fault #3 should not be penetrated if the location is correct However, the location uncertainty (250') exceeds the distance from the well TD to the expected fault location (150'). We could encounter this fault up to 100' md before the proposed TD. Look for Kingak, Sag or Shublik within 200' of TD. Stop drilling at fault. If lost circulation problems are experienced while crossing fault #2, then approach fault #3 conservatively. ~ TD will be picked by the wellsite geologist in collaboration with the town Geologist. TD well sooner if northern fault is encountered early, as evident by Kingak, Sag or Shublik. TD may be called earlier if drilling conditions are poor and at least 500' of the north fault block is drilled. ~ KICK TOLERANCE: In the worst-case scenario of 8.3 ppg pore pressure in the Ivishak, a fracture gradli~. rf ,9.5 ppg at the 7" casing shoe, and 8.5 ppg mud in the hole, the kick tolerance is I~ Reference RP .:.

Þ- Ensure the liner top packer is set prior to POOH. Slack off with rotation to the maximum allowable down weight, as per Baker representative. ~ Sufficient 4-1/2" liner will need to be run to extend -150' back up into the 7" intermediate liner. ~ Condition mud after casing is on bottom prior to pumping cement.
