The NK-65A injector has been the sole source of injection in the pool since October 2005. During this time the greater Raven area has been undergoing initial development with ultimate Raven Pool boundaries undefined at this time. Two wells, which are outside the defined area of the ROP (NK-14B and NK-08B) are producing under a GOR waiver via 25.240(b)(3) for acquisition of performance data in order to define an optimum reservoir management plan. In this application, Hilcorp North Slope LLC, as operator of the Prudhoe Bay Unit, respectfully seeks Administrative Approval under Rule 14 within CO 570.011 for the re-categorization of the defined area of the ROP to: 1. Produce under GOR waiver via 25.240(b)(3) in support of development of the greater Raven area, and 2. That the wells within the currently defined ROP as well as the NK-08B and NK-14B tract operations produce under a common GOR waiver The North and Central Raven blocks are within the defined area of the ROP as shown in Figure I. To improve the ultimate recovery of these blocks the proposed plan is to convert NK-65A to assess the recovery potential of the Ivishak and Sag rich gas. This plan to improve the ultimate recovery is predicated upon the following: • The Ivishak oil reservoir in the North and Central Raven fault blocks are at or near maturity • Rich gas potential exists in the Sag River formation, as proven by the recent NK-15A conversion • The production data collected from conversion of NK-65A to a rich gas producer will provide the necessary information to progress the development of the greater Raven area. The North and Central Raven blocks were developed with four development wells. The North Raven block was developed with the NK-65A injector and NK-38A producer. In 2016, the North Raven block reached maturity and the NK-38A was subsequently sidetracked into the Central Raven block, becoming the NK- 38B producer. In 2018, the NK-15A sidetrack was drilled into the Central Raven block to complete the development of the Central Raven block. However, when NK-15A was drilled the Ivishak was found to be swept by waterflood. As the NK-15A is a horizontal well, the area logged within the block was extensive, both vertically and laterally. Furthermore, when the Ivishak was tested in the NK-15A well it was found to be primarily sea water, which could have only come from the NK-65A injector [Figure II]. Page 2 of 5 Hilcorp North Slope, LLC The logs, production test, and water chemistry from NK-15A show the Central Raven block in this area has reached maturity from NK-65A’s water injection. The NK-38B is nearing maturity, with water cuts currently at approximately 95%. The pressure and GOR at NK-38B have remained relatively constant throughout the life of the producer. As NK-65A has been shut in since May of 2020, the pressure support can be attributed to gas cap expansion and aquifer encroachment. Therefore, the small amount of remaining recoverable reserves associated with NK-38B will be recovered without the support of the NK-65A injector. As no further utility in the Ivishak was identified, in 2020 the Sag River formation at NK-15A was tested as evidence suggested rich gas potential that could result in recovery of additional saleable hydrocarbons. This test was successful and the NK-15A was converted to a Sag Rich Gas producer [Figure III]. Cumulative production from November 2020 to July 2021 is 140 thousand stock tank barrels of oil and the well is currently producing 700 barrels of oil per day. With the conversion of NK-65A to production, the timeline for development will be as follows: • Produce NK-65A for 30 calendar months, collecting production and pressure data o An assessment of the greater Raven area development plan will be completed within this 30-calendar month period o An assessment of an enhanced oil recovery project to support the production from the NK- 08B and NK-14B tract operations, the currently defined ROP, as well as the greater Raven area will be completed within this 30-calendar month period • An application for expansion of the Raven Oil Pool at the end of the 30-calendar month period will be submitted, if warranted The 30-calendar month period will provide two winter drilling seasons at Niakuk to assess the greater Raven area development potential for potential expansion of the Raven Oil Pool.

PO Box 196612 Anchorage, Alaska 99519-6612 Alaska Oil and Gas Conservation Commission 333 West Seventh Avenue Anchorage, Alaska 99501-3572 Main: 907.279.1433 Fax: 907.276.7542 www.aogcc.olaska.gov RE: Docket No. CO -20-007 Request to retroactively extend the waiver of the gas oil ratio limitations of 20 AAC 25.240(a) for well Prudhoe Bay Unit Niakuk 14B (PTD 217-005) Dear Ms. Garner: By letter dated May 7, 2020, BP Exploration (Alaska) Inc. (BPXA) requested a retroactive two-year extension to the waiver of the gas -oil ratio (GOR) limitations in 20 AAC 25.240(a) that the Alaska Oil and Gas Conservation Commission (AOGCC) granted on July 24, 2017 and extended on July 20, 2018. The basis for the request is to continue to collect reservoir performance data necessary to develop a technically sound development plan for the area. BPXA's request is hereby granted under the conditions below. The NK 14B well was completed in the Sag River formation, is located adjacent to the Raven Oil Pool, which includes the Sag River Formation, and is the first well in this portion of the field to produce exclusively from the Sag River Formation. BPXA was granted a temporary waiver of the GOR limits established in 20 AAC 25.240(1) for the NK 14B well to collect reservoir performance data to determine how best to develop the Sag River formation in this area. The liner hanger in the NK 14B failed and resulted in an impaired integrity barrier. In September 2017 the well was shut in until it could be repaired. The well was not returned to production until March 2018. Because of the extended shut in BPXA was not able to collect the bottomhole pressure and production performance data that it anticipated collecting during the original waiver period. On July 20, 2018, the AOGCC granted a one-year extension to the GOR waiver to allow for the collection of data that was not able to be collected during the initial GOR waiver period due to the well's mechanical issues, the extension ran through August 1, 2019. In May 2019 the AOGCC and BPXA had discussions about the testing of this well, the need to collect additional information, and whether the AOGCC would agree to a two- year extension. Due to unforeseen circumstances, a formal request to extend the GOR waiver was never filed and the well has produced since August 1, 2019 without a valid GOR waiver. The NK 14B well initially produced with a GOR of approximately 2,000 Ms. Katrina Garner June 1, 2020 Page 2 of 2 scf/stb and currently produces with a GOR of approximately 3,000 scf/stb. During the period after the GOR waiver had expired, the well generally produced with a GOR in compliance with 20 AAC 240(a), which indicates that the reservoir performance has not been harmed by this unforeseen lapse, and BPXA has continued to submit the quarterly well testing reports as required by the previous approvals. The data that BPXA is collecting is necessary to validate the reservoir model developed for this area and to determine an optimal development strategy. Due to the need to continue collecting this data, BPXA has asked for a two-year retroactive extension to the GOR waiver in order to keep the well on production. In accordance with 20 AAC 25.240(b)(3) BPXA's request for a retroactive extension is granted on the following conditions: 1) 2) 3) 4) The PBU NK14B well must be tested in accordance with the PBU's well testing and allocation procedures and be tested at least twice per month while flowing. The GOR waiver expires on August 1, 2021. On a quarterly basis, the operator must submit copies of all well tests for the PBU NK 14B well showing the GOR at the time of the test. Prior to the expiration of this GOR waiver, and allowing for enough time to provide notice and hearing if necessary, the operator shall take steps to make this development compliant with 20 AAC 25.240(b)(1) or (2), or with 20 AAC 25.240(c).

BP Exploration (Alaska), Inc. 900 East Benson Boulevard Post Office Box 196612 Anchorage, Alaska 99519-6612 Telephone (907) 564 581 May 7, 2020 Jeremy Price, Chair Alaska Oil and Gas Conservation Commission 333 West 7t'' Avenue, Suite 100 Anchorage, AK 99501 0 by RE: Request for Administrative Approval for Retroactive Re -Extension of Waiver of the gas oil ratio limitations of 20 AAC 25.240(a) for well Prudhoe Bay Unit Niakuk 14B (PTD 217-005) Dear Chair Price, On July 20, 2018 the commission granted BP Exploration (Alaska) Inc's (BPXA) request for a one-year extension to the waiver of the gas -oil ratio (GOR) requirements of 20 AAC 25.240(a) that had been granted on July 24, 2017. The GOR waiver expired on August 1, 2019. At this time BPXA respectfully requests a two year re -extension of the GOR waiver, with all other conditions remaining the same, on a retroactive basis. BPXA discussed submitting an application for re -extension for two year duration with Commission staff in May, 2019 in anticipation of the August, 2019 expiration, but due to unforeseen circumstances, did not timely file the request. More production data to support development of a long term depletion plan are needed. BPXA has generated a reservoir simulation model and, with continued collection of data, anticipates being able to have a technically sound development plan for the area in 2021. The Niakuk-14B GOR is currently at 3,000 scf/stbo versus initial tests of 2000 scf/stbo, and over the period from August, 2019 to present has generally remained less than double the Application for Administrative Approval Niakuk 14-B GOR Waiver original.' May 7, 2020 The additional data to be gathered are important to have in order to ensure greater ultimate recovery in this reservoir. Without these data, sub -optimal decisions could be made about reservoir management which could put recoverable resources at risk. In summary, BPXA seeks retroactive approval for an additional two years of waiver from the requirements of 20 AAC 25.240(a), in accordance with 20 AAC 25.240(b)(3), until August 1, 2021.

A MIT-T to 2600 psi passed. A CMIT-TxIA failed with a LLR of 3bpm at 1300psi. An LDL identified a leak signature at the 7" liner hanger. Objective This cement job is to repair a leak across the 7" liner hanger and make this well operable. Cement will be circulated down the CT and up the IA to cover the leak. The new TOC in the IA will be -12,000'md. Expected Start Date: December 8, 2017 Post-Job Evaluation This well is a gas lifted producer; an AA will not be applied for. The following BP internal criteria to evaluate the integrity of the non-rig workover will be applied: • MIT-IA • SCMT • MIT-T Long-Term Integrity Monitoring • Record WHPs daily (includes pressure monitoring of the Inner Annulus to be cemented to -12000'MD). • -4 year (quadrennial) MIT-lAs and MIT-Ts K r7 J Kit..

Please find the answers to the questions you raised yesterday.You can call me on 748-1140 if you need anything else. Thanks Ryan • How do we differentiate Kuparuk water from Cret water samples..?We do not have a way to differentiate Cretaceous and Kuparuk water using water chemistry alone.The water sample was taken from the production stream,this well was operated briefly with and without gas lift and has a deep OGLV at 16056'. • Did we perform an FIT before the window exit was drilled out?We performed a 4000 psi pressure test against the casing prior to milling out the window.We also performed a successful LOT to 13.2 ppg EMW after the window was milled. • Do we think the remedial cement job while drilling successfully isolated the sidetrack NK-14B Kuparuk...most likely source of water is Cret?Yes,we think the remedial cement job while drilling was successful.We have USIT results that show cumulatively we have>56' MD good cement between the Kuparuk and the 9-5/8" window.Given the data we have available,the most likely water source is either Cretaceous from above the NK- 14B sidetrack drilling squeeze,or from below via a cement channel along the NK-14A 9 5/8" casing. Either of these two mechanisms are mitigated by the planned intervention options for repair. • There is no obvious SCP in the OA.After the well was brought online,the OA increased to 500 psi; however, after being bled down, it has remained<100 psi.We have no indications of SC integrity issues. NK-14B does have SCP in the IA now. 2 • • O N 0 2 D o N co O 0 N O co N- O n O 0 a N CO O ^ O J J J CV Z YJ Yo J 0 I -o N Z Z of of O cr o E o) 5U NI 2 to I� o c CV ns °I 2 31 C p Y _ a I U w 2 U) ttl T 0 m e m o cl c a a Z Za) • T a N a) a) O a)• UI O UI C C Z a) o •a) a) a) Q U as QTs m 'm c ay l aai Z co l Z aa) Z _5 13 Z d Q cci U aci aci aci c co it lL QQI �' QI W Q J m it I it.

PO Box 196612 Anchorage, Alaska 99519-6612 RE: Docket No. OTH-17-020 Request for a waiver of the gas oil ratio limitations of 20 AAC 25.240(a) for well Prudhoe Bay Unit Niakuk 14B (PTD 217-005) Dear Ms. Richmond: By letter dated July 20, 2017, BP Exploration (Alaska) Inc. (BPXA) requested a 12 month waiver of the gas-oil ratio (GOR) limitations in 20 AAC 25.240(a). The basis for the request is to allow long term testing of the Prudhoe Bay Unit (PBU)Niakuk 14B well (NK 14B) to acquire reservoir performance data for a portion of the Sag River formation that is currently outside any of the defined pools in the PBU to help determine the potential for additional reservoir development. BPXA's request is hereby granted under the conditions below. The NK 14B commenced drilling in May 2017 and was completed in the Sag River Formation in June 2017. To date seven short-term production tests have been conducted on-to gather reservoir performance properties. Recent well tests have had producing GORs in excess of twice the initial GOR so BPXA has shut in the well to be in compliance with 20 AAC 25.240(a). The Sag River Formation is a part of the adjacent Raven Oil Pool' but to date no standalone wells have produced from the Sag River Formation for an extended period of timet. BPXA proposes to produce the NK 14B for 12 months during which time it will gather data on compartmentalization, aquifer strength and connectivity, and hydrocarbon pressure, volume and temperature properties to be able to develop a prudent reservoir development strategy for the Sag River Formation in this area. In accordance with 20 AAC 25.240(b)(3) BPXA's request is granted on the following conditions: • The Raven Oil pool is comprised of sands in the Sag River Formation, Shublik Formation, and Ivishak Formation 2 The PBU NK43 well has produced from the Sag River Formation for a number of years but has been commingled with the production from the overlying Kuparuk River Formation for virtually its entire productive life. • • Ms. Dianne Richmond July 24, 2017 Page 2 of 2 1) The PBU NK14B well must be tested in accordance with the PBU's well testing and allocation procedures and be tested at least twice per month while flowing. 2) The GOR waiver expires on August 1, 2018. 3) On a quarterly basis, the operator must submit copies of all well tests for the PBU NK 14B well showing the GOR at the time of the test. 4) Prior to the expiration of this GOR waiver, and allowing for enough time to provide notice and hearing if necessary, the operator shall take steps to make this development compliant with 20 AAC 25.240(b)(1) or (2), or with 20 AAC 25.240(c).

If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The Commission shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10-days is a denial of reconsideration. If the Commission denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the Commission mails, OR 30 days if the Commission otherwise distributes, the order or decision denying reconsideration,UNLESS the denial is by inaction,in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the Commission grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the Commission,and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the Commission mails, OR 30 days if the Commission otherwise distributes,the order or decision on reconsideration. DAVE: .080(b)was repealed a few years ago. In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m.on the next day that does not fall on a weekend or state holiday.

(BPXA), operator of the Prudhoe Bay Unit, submits this application to waive the gas-oil ratio (GOR) limitations of 20 AAC 25.240(a)for the Niakuk 14B well (NK-14B). BPXA completed the NK-14B in June of 2017 in the Sag River Formation (see Figure 1 in the confidential attachment to this application). To date seven production tests have been acquired: NK-14B Tests: Date BOPD GOR Water Cut (stb) (s /stb) (%) 7/11/2017 2801 4340 4.6 7/8/2017 3147 3920 4.7 7/7/2017 3379 3663 4.7 7/4//22017 3815 3073 4.8 7/112017 4169 2128 4.9 6/30/2017 4964 2163 5 6/29/2017 4469 1804- 5 • • BPXA Application to AOGCC Waiver of GOR Limitations in 20 AAC 25.240(a) July 20, 2017 Page 2 Tested GOR has gone from 1804 scf/bbl to 4340 scf/bbl, an elevating trend within 14 days of production. The well is currently shut-in. Request For Waiver Under 20 AAC 25.240(b)(3)—Acquisition of Pool Performance Data BPXA requests that the commission grant a waiver under 20 AAC 25.240(b)(3), for a minimum period of 12 months,to allow time for the acquisition of pool performance data. NK #14B will be the first instance of prolonged Sag River-only production in the Raven Oil Pool. BPXA needs well performance data during this 12 month period in order to devise a development plan optimized to the Sag River Formation in the area of NK #14B. It's crucial that NK #14B be continually produced during this period. Three main pieces of performance data are needed for the development of other Sag River opportunities in this area: • Compartmentalization data; • Aquifer strength and connectivity data; and • Hydrocarbon pressure,volume and temperature (PVT)Testing During the year-long production period, BP will acquire key data including decline analysis, a pressure build-up, representative fluid sample for full PVT testing, and water ion analysis. BPXA will use this data to devise a prudent reservoir management and development plan. Request For Waiver Under 20 AAC 25.240(b)(1)and (2) In the event the commission declines to approve a waiver under 20 AAC 25.240(b)(3), then in the alternative BPXA requests that the commission grant a waiver under either 20 AAC 25.240(b)(1)or(b)(2). 20 AAC 240(b)(1) allows the waiver of GOR limitations if an enhanced recovery project operates in the pool from which the well is producing. 20 AAC 240(b)(2) allows the waiver of GOR limitations if produced gas is being returned to the same pool. BPXA respectfully asserts that both of these subsections apply to the NK#14B well, because the well was completed in the Raven Oil Pool. (Enhanced recovery operations and the return of produced gas are both occurring in the pool.) AS 31.05.170.12 defines a "pool" as follows: (12) "pool" means an underground reservoir containing, or appearing to contain, a common accumulation of oil or gas; each zone of a general structure which is completely separated from any other zone in the structure is covered by the term "pool"[.] (Emphasis added.) The commission formally recognized in Conservation Order 570 (CO 570) that certain lands and formations were encompassed within the Raven Oil Pool (for convenience those lands and zones are referred to as the "CO 570 ROP"). However, BPXA respectfully submits that the actual limits of the • • BPXA Application to AOGCC Waiver of GOR Limitations in 20 AAC 25.240(a) July 20, 2017 Page 3 "common accumulation of oil" in the Raven Oil Pool extend beyond the CO 570 ROP lands, and that the pool encompasses the completion zone and producing area of the NK#14B well. BPXA offers the following evidence in support of this assertion: The Sag River Formation is one of the defined reservoirs for the Raven Oil Pool in CO 570, and is consistently present across both the area of the NK-14B well and across the Raven Oil Pool recognized in CO 570. Pressure depletion of 150 psi measured in the NK-14B compared to the original exploration well (NK-02A) data from 1977 in the same fault block suggests a connection due to production depletion in Sag and Ivishak formations, as seen in other fault blocks in the CO 570 ROP. Hydrocarbon properties in NK-14B are similar to hydrocarbons in the CO 570 ROP —A Sag-only sample was collected from NK-43 that is within the ROP area. The well produced only from the Sag for a short time and fluids collected were used to accurately predict the API and original GOR of the NK-14B. Unfortunately,the sample did not have all the necessary tests performed and with NK-43 now commingled with Kuparuk, we are unable to collect more Sag only oil for additional testing required. Fault Juxtaposition confirmed for Sag River and Ivishak for continued combined reservoir pool definition (Sag/Shublik/Ivishak for ROP) as shown in Figure 2 in the confidential attachment to this application. With additional production data, BP expects to be able to justify an application to expand CO 570 ROP to encompass the NK-14B area. For all the reasons discussed above, BPXA respectfully requests that the commission grant a waiver from the GOR limitations in 20 AAC 25.240(a)for the NK-14B well for a minimum period of 12 months. BPXA desires to produce this well after the Lisburne Production Center turnaround, which is due to complete on July 24. Therefore, the commission's earliest consideration of this request would be greatly appreciated so that we may return this high rate well to production.

Subject: H2S Alarm on NK-14 All, (?T1 2')7Oo$) On PBU NK-14B (API-50-029-22668-02) Friday morning, we experienced an H2S alarm of 21 ppm for approximately 4 seconds. The incident occurred on the floor of the Well Work Platform when the lubricator,that is above the BOP stack, was moved up 6" to gain access to the BHA. Three individuals were on the work platform at the time, they all had personal monitors that did not alarm. Subsequently we took readings with a 4 gas monitor and wand and were unable to detect any other H2S. The lubricator was made up again to secure the well for further evaluation. Through further hole conditioning and pumping out to our return tanks we were never able to detect H2S. With the handheld 4 gas meter we did detect Carbon Monoxide CO, inside the tank, but in all work areas no harmful gases were detectable. We completed our work on the well and are currently in the process of rigging the Coil Unit down. Please call with any questions. Clark Olsen Well Superintendent -Coil Tubing Office 907-659-5542 1 • MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission Keil6/ sail? TO: Jim Regg DATE: June 15, 2017 P. I. Supervisor FROM: Brian Bixby SUBJECT: Klondike CTU Site Visit Petroleum Inspector PBU NK-14B - BP Exploration PTD 2170050;Sundry 317-195 6/15/17: This was a follow up visit regarding concerns from a previous BOPE test: 1. Proper procedure for conducting the Drawdown Test on the accumulator. _ 2. Gas Alarms 3. Micro Motion alarms - I first stopped by the PBOC and talked to Clark Olson (BP Superintendent) and discussed the three concerns that came up on a previous BOPE test. I had just returned from R&R and was not totally up to speed with all the concerns, what has been done and where they are at with it. We talked about the concerns listed above and he totally agreed that they are all valid concerns. He was going to go thru email and get back with us as soon as he knew more. I then went to location where the Klondike is currently rigged up on PBU NK-14B and had a good discussion with Mark Igtanloc (Well Site Leader/ Company man for the Klondike Work Platform). We also discussed all three concerns and he will get with Clark and get back with us. Mark agreed with the corrective actions listed below and said he would get with Clark and work on getting these fixed. Below are what we talked about and the fixes. 1. Have a procedure in place for which ever coil unit is rigged up to the Klondike for testing BOPE and step by step procedure for the drawdown testing including have the unit idled up to operating speed (approximately 1900 RPM) 2. Have H2S and LEL detectors on the rig floor, cellar and the flowback tank along with adequate strobes and audible in each location along with the ones on the OPS cab. An Amber strobe for H2S, Red strobe for LEL and distinct different audible sounds for each gas. 3. They will get the alarms working for the Micro Motion to flash on the screen for a low alarm and have an audible for the high alarm.

Due to time and cost constraints, the rotary rig - moved off the well and left the well unperforated. This program is to open hole deploy an extend length of perforating guns to complete the initial perforating of the well. The rig experienced some issues with the liner cement job, the plug did not bump and the floats did not hold. It is expected that service coil will need to clean out some cement stringers in the liner prior to perforating. Scope of Work: The primary objective of this intervention is to initially perforate the well.

In accordance to the current Sundry requirements, we do not submit perforated intervals prior to the interventions job, we supply a 10-404 following the intervention with the perforated footage including the TVDs. In this case, as in most cases, we have our target intervals to perforate picked out but will optimize the final footage to be perforated based on the drift run's success getting to the total depth of the well and our pick up weights while pulling out of the hole. As noted in the Sundry,the planned number of perforating runs is 5. If we cannot operationally run ''500' of perforating guns in one run we will have to break the guns up into more runs or limit our footage to shorter than 1545'.These decisions will be made real time during the intervention. Thanks, Jaime Bronga From: Davies, Stephen F (DOA) [mailto:steve.daviesOalaska.gov] Sent: Friday, May 12, 2017 3:21 PM To: Bronga, Jaime Subject: FW: PBU NK-14B (PTD No. 217-005, Sundry No. 317-195) Jaime, The Planned Wellbore Configuration diagram that accompanies BP's application to perforate PBU NK-14B displays" ^'1545' of initial perfs", but the measured and true vertical depths of the planned perforations are not provided. I'm certain that you can appreciate my reluctance to approve a perforation program when the depths or ranges of depths are not provided in an the application. Please provide them. If you are not certain as to those depths, what information must BP acquire to make the final perforation-depth determinations? When will BP acquire the information?When will BP make the perforation-depth determinations?

Unfortunately,the liner was backed off below the perforations causing a change to the planned completion design.To isolate the perforations from the produced fluids we will run a two production packers on the completion string.The upper completion packer will act as the true completion packer isolating the perforations from the gas lift pressure above.The lower completion packer will isolate the produced fluids from the perforations in the 7" liner.A schematic is attached to show the proposed completion. Below is a brief summary of our plans. Feel free to email or call me if you have any questions. 1. Run 4-1/2"Vam Top completion with 2 x HES production packers. 2. Space out unique overshot over the 4-1/2" liner stub. 3. Circulate in corrosion inhibitor. 4. Drop ball and rod.Set both production packers 5. Test tubing to 4,000' psi, hold 2,200 psi on tubing and test IA. 6. Bleed off tubing pressure Shear DCK valve 7. Freeze protect tubing. 8. Install TWC Pressure test from above and below to 4,000 psi 9. ND BOP, NU tree. 10. RDMO *Note the rig will not be perforating NK-14B.A cleanout run is required prior to perforating the 4-1/2" Liner. It was determined that a coil tubing unit could perform a cleanout run and perforate the well in a safer and more cost effective manner.

field copies of the logs. Based on Gerardo's interpretation that there is-56' of annular isolation above the Kuparuk there is to move forward with operations,and drill the production hole. Below is a brief summary of our planned operations. Please let me know if you have any question or concerns regarding our interpretation, or the below plan forward. 1.) RU and conduct a FIT to 11.7 ppg EMW at the upper perforation (estimated surface pressure of 520 psi assuming a 10.6 ppg MW with the perforation at 9088'TVD.) per the SOP: Leak-Off and Formation Integrity Tests. Note 11.7 ppg EMW gives a kick tolerance of 25 bbls. Hold Point:Send FIT results to the ODE for approval. If an FIT of 11.7 ppg cannot be achieved a new plan forward will be required. 2.) Test BOPs. 3.) MU production hole drilling BHA. 4.) RIH to 17,260' MD above the previous shoe track. 5.) Displace the well to 9.8 ppg solids free QuikDril-N. 6.) Perform a minimum of 30 min no flow test. 7.) Drill out remainder of the 7" shoe track 8.) Perform 15 min flowcheck prior to drilling new formation. 9.) Drill 20'of new formation. 10.)Circulate bottoms up 350 gpm and pull back into the 7" shoe. 11.)Perform a FIT as per the SOP: Leak-Off and Formation Integrity Tests.A minimum of 11.1 ppg EMW is required to satisfy the Kick Tolerance requirements for the well. Send FIT chart to ODE for approval. 12.)Drill production hole section per PTD.

Kyle<john.raese@bp.com>wrote: Victoria, The 7" intermediate liner was originally planned to be cemented from the shoe with top of cement 1500'above the Kuparuk formation.While pumping with some cement outside the shoe,the open hole 1 packed off. Circulation was unable to be reestablished.As a result,our ojective of isolating both the Sag River and Kuparuk formations was not achieved. A cement evaluation log(USIT)was run from the 7" landing collar up to top of cement.Top of cement was logged at 16,446' MD(see attached interpretation).This provides sufficient isolation to the Sag River(Top Sag at 17,347' MD). However,this top of cement does not provide sufficient isolation to the Kuparuk. Raw files of the cement evaluation logs are also attached. Given that cement has failed to isolate the Kuparuk formation,we propose the following remedial work. This is our primary plan and is shown on the attached schematic: 1. Set 7" bridge plug at 16,426' MD 2. Perforate 7" liner at 16,346' MD(100' MD above logged top of cement) 3. Set 7"cement retainer at 16,266' MD 4. Establish circulation path down drill pipe through cement retainer to perforations and up to the top of liner via the open hole annulus 5. If circulation can be established, pump cement to cover 1500' MD open hole above Kuparuk 6. Set 7"liner top packer and pressure test 7. Proceed to production hole drilling per original plan If circulation through the perforations is not possible(likely HRZ shale collapse),we propose the following contingency to verify Kuparuk isolation (scenario not shown on attached schematic): 1. Set 7" liner top packer and pressure test 2. Perforate liner at 16,248' MD above(98'above lower perforations) 3. Establish circulation path down drill pipe through cement retainer to lower perfs and up the open hole annulus to the upper perfs a. If circulation not possible(likely indicative of HRZ shale collapse): i. Perform LOT through bottom perf ii. Place balanced cement plug on top of cement retainer iii. Squeeze some of balanced plug into upper perforations b. If circulation possible(no shale collapse between perf zones): i. Pump cement down drill pipe through cement retainer into open hole annulus between perforations(for 98'annular cement between perfs) 4. Proceed to production hole drilling per original plan We request your approval to proceed with this proposed operation. Please contact me with any questions.

The planned well is a two string rotary sidtrack targeting the Sag River in the Raven prospect north of Niakuk.The scope of the sidetrack includes pulling existing tubing, milling an 8-1/2"window out of the existing 9-5/8"casing, drilling a 8-1/2" intermediate hole, running a 7" liner, drilling a 6-1/8" production hole, running a 4-1/2" soild liner, and running a 4-1/2"completion. The intermediate casing will top set the Sag River reservoir, and the production liner will be cemented. The maximum anticipated surface pressure from the Ivishak with a full column of gas from TD to surface is 3,942 psi (assumes 9.4 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). • The well will be drilled by Parker 272 using the' 5,000 psi four preventer BOP stack(3 rams and an annular). The BOP rams will be tested to 4, psi and annular to 3,500 psi. A detailed operations summary is includ with the permit application. 13 00/2 5 -1 �G 1-7 If there are any questions concerning information on NK-14B, please do not hesitate to use the contact information below.

NK-09 recently recorded 4450 psi (9.3 ppg) in 2015 and the NK-14 mother bore recorded 4304 psi (9 ppg) in 2006. Sag River and Ivishak Pressure: The Sag River and Ivishak Formations are assumed to be at virgin pressure ofn'9.4 ppg originally recorded in the NK-02A DST. It is unknown if the fluid type in the Sag River will be a gas condensate or a light oil. The Ivishak is expected to be a light oil. Assuming the Sag and Ivishak are both gas condensate generates the most conservative pore pressure represented above. Anti-Collision: None. All offset wells pass BP Anti-collision Scan Criteria. NK-14B PTD 4 1/12/2017 • • Offset well ownership information All offset wells identified within 200 ft of the proposed wellbore are operated by BP.

NK-14B PTD 8 1/12/2017 • • NK-14B Drilling Critical Issues POST THIS NOTICE IN THE DOGHOUSE I. Well Control/ Reservoir Pressures A. Intermediate Hole: The WS1 is expected to be a 9.1 ppg EMW. The CM1, CM2 and CM3 are expected to be a 10.0-10.3 ppg EMW. Formation pressures will be controlled with a 9.5 — 10.3 ppg mud to drill to within 200' MD of the CM3. At this point, there will be a weight up to 10.3 — 11.0 ppg to drill the rest of the interval to TD. B. Production Hole: The Sag River and Ivishak are expected to be at a 9.45 ppg EMW. Reservoir pressures will be controlled by using 9.6— 10.2 ppg water based mud. II. Lost Circulation/Breathing A. Intermediate Hole: Breathing has been known to occur in the Colville at Niakuk as a result of high ECD's. Also there is a chance that losses could be encountered by drilling into a fracture at the casing point in the Sag River. B. Production Hole: Historically Sag River wells have had Lost circulation especially where multiple faults and fractures are encountered. The well path does not exect to cross any faults. The Niakuk Sag River formation has similar characteristics to the Sag found in the north west of the main field of Prudhoe Bay near R and F Pads. The Sag River formation in these areas has had less severe instances of lost circulation than in other areas where losses occurred but were managed with conventional LCM. III. Fault Locations No fault planned fault crossing, but there may be sub-seismic faults in the production hole. IV.

Anti-Collision Issues D None. All offset wells pass BP Anti-collision Scan Criteria. VII. Wellbore Stability A. Intermediate hole—Niakuk has a history of mechanical instability in the HRZ and Kingak shales. The planned well path and MW should mitigate this risk, but observes signs of instability should be acted upon as quickly as possible. B. Production hole—Instability has been experienced while drilling thru the Shublik formation. There is also the possibility of faulting into the Kingak formation.

Please see the center to center distances below.

Since the NK-02 wells have been fully abandoned the consequence of a collision would result in a open hole sidetrack to avoid hitting them again. During the drilling of the well NK-14B will always have kill weight fluid in the well to control wellbore fluids if they were somehow able to migrate up thru the abandonment plugs. With the above considerations there is no further actions or mitigation measures required to mitigate a collision. Please feel free to call me on my cell phone if you would like to discuss this further.
