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.

Increasing Sulfates and decreasing Barium concentrations are indicative of increasing sea water production as a percentage of total water production. The trend of production transitioning from connate water to sea water can be seen with the NK-38A water chemistry data.

In the prod-geo tab there is just the ROP (640147) under pools encountered. Should I add in the Sag undefined pool as well? Huey From: Roby, David S (DOA) Sent: Monday, April 15, 2019 3:20 PM To: AOGCC Reporting (DOA sponsored) <aoecc.reporting alaska.eov> Subject: Change in reporting for PBU NK -14B (PTD 217-005) The subject well is currently reporting production to the Raven Oil Pool (640147) but is actually completed in a portion of the Sag River formation that is outside of the ROP. Can you please let your contact at BP know to start reporting production for this will against the Sag River Undefined Oil Pool (640165)? Do we need BP to submit revisions for the past production, or can we just go into RBDMS and change the field and pool code for the roughly year and a half of production we have for this well? On a related note, BP is currently drilling the NK -08B well (PTD 217-154) that's going to be completed across the ROP boundary, so it'll be reporting production for both the ROP and the Sag Undefined pool based on the completion length on either side of the boundary. We're going to tell them in a GOR waiver letter that's going out shortly to do this split this way. The well should come on line next month so we won't see any production from it until we get the reports in June.

PO Box 196612 Anchorage, Alaska 99519-6612 RE: Docket No. OTH-19-013 Request for waiver of the gas oil ratio limitations of 20 AAC 25.240(a) for well Prudhoe Bay Unit Niakuk NK -08B (PTD No. 217-154) Dear Ms. Garner: By letter dated April 9, 2019, BP Exploration (Alaska) Inc. (BPXA) requested a two-year waiver of the gas -oil ratio (GOR) limitations in 20 AAC 25.240(a) for the Prudhoe Bay Unit (PBU) well Niakuk NK -08B (NK -08B). BPXA's request is hereby GRANTED under the conditions below. The NK -08B, spudded on March 27, 2019, targets the Sag River Formation with the majority of the producing interval in the Raven Oil Pool (ROP). A portion of NK -08B will extend beyond the boundaries of the defined ROP. The ROP has a GOR waiver based on an ongoing enhanced oil recovery project in the field. However, the GOR waiver does not extend to the portion of the well that is outside of the defined pool boundaries. BPXA requests the GOR waiver to collect reservoir performance data in support of a probable future expansion of the ROP and to evaluate development of the Sag River Formation. BPXA requests a two-year waiver because the NK -08B well is a part of a larger ongoing evaluation of the Sag River Formation and expansion of the ROP that includes interpretation of newly collected seismic data across the area. Included in BPXA's assessment is a performance evaluation of the NK -14B well (PTD No. 217-005) that is also testing the Sag River Formation beyond the bounds of the ROP. Additional Sag River Formation appraisal wells may also be drilled to evaluate the formation and expansion of the ROP. BPXA's request under 20 AAC 25.240(b)(3) for a GOR waiver is granted on the following conditions: Ms. Katrina Garner April 17, 2019 Page 2 of 2 1) The NK -08B 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 at the end of the month two years from the date of first production. 3) On a quarterly basis, the operator must submit copies of all well tests for NK -08B showing the GOR. 4) Production from NK -08B will be allocated between the ROP and the Sag River Undefined Oil Pool based on the percentage of the completed interval that is on either side of the pool boundary. The field and pool code for the Sag River Undefined Oil Pool is 640165. 5) 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). DONE at Anchorage, Alaska and dated April 17, 2019. Qg���p l Daniel T. Se ount, Jr. riehmielowski Commissioner oner TION AND APPEAL As provided in AS 31.05.080(a), within 20 days after written notice of the entry of this order or decision, or such further time as the Commission grants for good cause shown, a person affected by it may file with the Commission an application for reconsideration of the matter determined by it. 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 ease 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. 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.

APR 12 20119 AOGCC Re: Request for a waiver of the gas oil ratio limitations of 20 AAC 25.240(a) for well Prudhoe Bay Unit Niakuk 08-B (PTD #217-154). Dear Commissioners Chmielowski and Seamount, In accordance with 20 AAC 25.240(b)(3), BP Exploration (Alaska) Inc. (BPXA), as the Operator of the Prudhoe Bay Unit, requests a two-year (24 -month) waiver of the gas -oil (GOR) limitations of 20 AAC 25.240(a) for the above -referenced well. The basis of this request is to allow long-term testing of the Prudhoe Bay Unit Niakuk 08-B well (NK -08B), which will result in reservoir performance data that will help determine an optimum reservoir management program. The Niakuk 08B spudded March 27, 2019 and is expected to complete drilling on April 25, 2019, with a first production date as early as May 5, 2019. The Sag River Formation is the primary target with secondary potential in the Ivishak Formation; these are the Raven Oil Pool (ROP) reservoirs. The trajectory of the NK -08B includes the majority reservoir portion within the defined ROP, with a minority of the reservoir portion outside of the defined ROP. There is a possibility that the GOR in the wellbore will rise to twice the initial or higher; because there is no guarantee it won't rise this high, BPXA is erring on the side of caution and requesting a waiver. An enhanced recovery project operates in the pool from which the majority portion of the well will be producing; the requested waiver is due to the portion of the wellbore that is outside the pool but within the same hydrocarbon accumulation. Adjacent areas to the effective area of the ROP are being evaluated through the interpretation of the new North Prudhoe 3D seismic survey and via drilling (e.g. Niakuk 14B, and anticipated additional wells to NK -0813). It is anticipated the ROP will eventually be expanded to encompass surrounding productive acreage. The two-year duration of the waiver is requested because longer learnings from NK -0813, combined with learnings from NK -14B and the anticipated additional wells, will be necessary to fully define the area for the pool expansion.

This sidetrack well is a ✓ horizontal producer targeting the Sag River sands. The planned well is a two string sidetrack exiting the existing 9-5/8" casing, installing 7" intermediate liner, and installing 4-1/2" production liner. The intermediate liner will be set at the top of the Sag River, and the production interval will be completed with a solid liner that will be fully cemented. The maximum anticipated surface pressure from the Sag with a full column of gas from TO to surface is 3,612 psi (assumes 8.79 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 4,000 psi. A detailed operations summary is included with the permit application. If there are any questions concerning information on NK -08B, please do not hesitate to use the contact information below.

Well Control / Reservoir Pressures A. Intermediate Hole: The formation pressure at the KOP is expected to be 9.1ppg. The formation pressure will be controlled with a 9.4 — 10.5ppg. The CM3, CM2 and CM1 are expected to be at 10.0 to 10.5 ppg EMW. Formation pressures will be controlled with a 10.5 — 11.5 ppg mud weight. C. Production Hole: The Sag is expected to be at an 8.94 ppg EMW. Reservoir pressures will be controlled by using 9.1 — 9.8 ppg water-based mud. II. Lost Circulation/Breathing A. Intermediate Hole: There are no expected fault crossings in the intermediate hole. However, breathing has been known to occur in the Colville on other Drill Sites in Prudhoe Bay as a result of high ECD's. B. Production Hole: There is 1 expected fault crossing in the production hole with a low risk of lost circulation. III.

This sidetrack well is a horizontal producer targeting the Sag River sands. The planned well is a two string sidetrack exiting the existing 9-5/8" casing, installing 7" intermediate liner, and installing 4-1/2" production liner. The intermediate liner will be set at the top of the Sag River, and the production interval will be completed with a solid liner that will be fully cemented. The maximum anticipated surface pressure from the Sag with a full column of gas from TO to surface is 3,535 psi (assumes 8.95 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 4,000 psi. A detailed operations summary is included with the permit-ap cation. If there are any questions concerning information on NK -08B, please do not hesitate to use the contact information below.

Well Control / Reservoir Pressures A. Intermediate Hole: The formation pressure at the KOP is expected to be 9.1ppg. The formation pressure will be controlled with a 9.4 — 10.5ppg. The CM3, CM2 and CM1 are expected to be at 10.0 to 10.5 ppg EMW. Formation pressures will be controlled with a 10.7 — 11.1 ppg mud weight. C. Production Hole: The Sag is expected to be at an 8.95 ppg EMW. Reservoir pressures will be controlled by using 9.1 — 9.8 ppg water based mud. II. Lost Circulation/Breathing A. Intermediate Hole: There are no expected fault crossings in the intermediate hole. However, breathing has been known to occur in the Colville on other Drill Sites in Prudhoe Bay as a result of high ECD's. B. Production Hole: There is 1 expected fault crossing in the production hole with a low risk of lost circulation. III.

(`BPXA"), operator of the Prudhoe Bay Unit ("PBU"), requested an order from the Alaska Oil and Gas Conservation Commission ("AOGCC") to define the Raven Oil Pool ("ROP") within the PBU, and to prescribe rales for governing the development and operation of the pool. Concurrently, BPXA requested authorization for enhanced recovery operations in the proposed ROP 2. The AOGCC published notice of opportunity for public hearing in the Anchorage Daily News on February 14, 2006. By e-mail correspondence dated February 13, 2006, the AOGCC requested additional information from BPXA in support of BPXA's application. 4. By correspondence dated March 3, 2006, and received by the AOGCC on March 6, 2006, Raymond C. Givens, attorney for the heirs of Andrew Oenga ("Oenga heirs"), notified the AOGCC that the Oenga heirs, as the owners of US BIA Allotment No. F-14632 and lessor of the land underlying the production facilities at Heald Point, requested the tentatively scheduled hearing be held March 30, 2006. 5. By correspondence dated March 9, 2006 and received by the AOGCC on March 13, 2006 the Inupiat Community of the Arctic Slope ("ICAS"), Federally Recognized Regional Tribal Government, objected to the Raven project until the lease dispute between BPXA and the Oenga heirs is settled. 6. By correspondence dated March 15, 2006, the AOGCC advised the ICAS that the hearing regarding BPXA's application would be held on March 30, 2006 at 9:00 am. 7. On March 24, 2006, BPXA submitted through e-mail correspondence the additional technical information requested by the AOGCC and requested a modification of the pool rules area. Conservation Order 570 (Corrected) January 28, 2019 Page 11 of 16 Affected Area: Umiat Meridian Township/Range Sections 12N -15E S/2SW/4 Section 24 E/2, NW/4, E/2SW/4 Section 25 E/2NE/4 Section 26 N/2NE/4 Section 36 12N -16E S/2NW/4, N/2SW/4, SWASWASection 29 All Section 30 NW/4NW/4 Section 31 Rule 1: Field and Pool Name The field is the Prudhoe Bay Field. Hydrocarbons underlying the affected area and within the herein defined interval of the Ivishak, Shublik and Sag River Formations constitute the ROP. Rule 2: Pool Definition The ROP is defined as the accumulation of hydrocarbons common to and correlating with the interval between log -measured depths 10,628 feet and 11,165 feet within Well NK -05. Rule 3: Well Spacing To allow for close proximity of wells in separate fault blocks, spacing within the pool will be a minimum of 20 acres. The ROP shall not be opened in any well closer than 500 feet to the external property lines where ownership or landownership changes. Rule 4: Casing and Cementing Practices In addition to the requirements of 20 AAC 25.030, the conductor casing must be set at least 75' TVD below the surface. In addition to the requirements of 20 AAC 25.030, the surface casing must be set at least 500' TVD below the base of the permafrost. Rule 5: Automatic Shut-in Equipment a. Upon completion each well shall be equipped with: 1. A fail-safe automatic surface safety valve (SSV) capable of preventing uncontrolled flow. 2. A fail-safe automatic surface controlled subsurface safety valve (SSSV), installed in the tubing string below the base of the permafrost and capable of preventing uncontrolled flow, unless other types of subsurface valve are approved by the AOGCC. b. A well that is not capable of unassisted flow of hydrocarbons, as determined by a "no flow" performance test witnessed by a AOGCC representative, is not required to have fail-safe automatic SSSV's. Davies, Stephen F (DOA) From: Roby, David S (DOA) Sent: Wednesday, January 23; 2019 2:27 PM To: Bredar, William L (William.Bredar@bp.com) Cc: Davies, Stephen F (DOA); Boyer, David L (DOA); Loepp, Victoria T (DOA) Subject: NK -08B well need for spacing exception Em After looking into whether or not a spacing exception for this well will be required the AOGCC has determined that we made an error when we adopted the spacing exception rule in CO 570. Namely despite BPXA asking for and us concluding a 500 -foot offset from property lines where ownership or landownership change was appropriate we adopted a rule, with no justification in the record, that was based on the pool boundaries and not based on ownership boundaries. We're going issue a corrected CO 570 to change the spacing exception rule to reflect that property lines where ownership changes, and not the pool boundaries, dictate when a spacing exception is required. Presuming the ownership and landownership on both sides of the pool boundary is the same, and that the other part of the spacing rule that requires a minimum of 20 -acre spacing is complied with, I believe this will eliminate the need for a spacing exception for this well. However, since part of the well will be completed outside of the pool boundary a GOR waiver might be necessary. We have no commissioners in the office this week, so it will likely be next week before we can get the corrected order out, but I've already gotten concurrence form the commissioners and our legal counsel to make this correction and wanted to let you know what we're going to do so you can plan accordingly in light of your desire to spud the well in March.

This nearly horizontal well, which targets the Sag River sands, will intersect the reservoir sands within the Raven Oil Pool, cross the external boundary of the pool, and then continue outside of the pool while remaining in the same sands. This violates the well spacing rule of Conservation Order 570, which states: To allow for close proximity of wells in separate fault blocks, spacing within the pool will be a minimum of 20 acres.
