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: x Wellbore diagram illustrating the current configuration of the well x Suspended Well Site Inspection form documenting the pressures and site condition Niakuk well NK-11A was suspended on 02/22/2002. 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 mechanically sound as proven by a pressure test of the casing, liner and cement plug on 02/21/2002. Based on these conditions and the inspection on 09/15/2019 Niakuk well NK-11A meets the provisions required in 20 AAC 25.110 (a)(1). Hilcorp North Slope, LLC 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)). In summary, Hilcorp believes Niakuk well NK-11A is mechanically sound and secure and meets the requirements for renewal of suspended status. If you have any questions, please call me at 907-777-8345 or Ryan Holt/ Andy Ogg at 659- 5102. Sincerely, Bo York PBE Operations Manager Digitally signed by Bo York DN: cn=Bo York, c=US, o=HIlcorp Alaska LLC, ou=Alaska North Slope, email=byork@hilcorp.com Date: 2020.08.21 10:10:06 -08'00' Bo York Attachments Technical Justification 2019 Suspended Well Site Inspection form Wellbore Schematic Niakuk Well NK-11A (PTD #202002) Technical Justification for Renewal of Suspended Status August 11, 2020 Well History and Status Niakuk well NK-11A (PTD #202002) was suspended on 02/22/2002 after problems running the liner in a sidetrack hole. The liner top packer prematurely set at 7618’ MD (about 2900’ MD above the intended depth) after an obstruction was encountered while running the liner. A retainer was set in the liner at 14100’ MD with 39 barrels of cement pumped below the retainer and the top of cement above the retainer at 13799’ MD. A 4-1/2” kill string was left in the well from surface to 2227’ MD. The well is mechanically sound as proven by a pressure test of the casing, liner and cement plug on 02/21/2002. 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, and 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 the Wellhead and Surface Location Niakuk well NK-11A is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. The well pressure readings are T/I/O = -/300/250 psi. Request Hilcorp North Slope, LLC requests approval for renewal of the existing suspension status for NK-11A. 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.

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.

The liner top packer prematurely set at 7618' MD (about 2900' above the intended depth) after an obstruction was encountered while running the liner. A retainer was set in the liner at 14100' MD with 39 barrels of cement pumped below and the top of cement above the retainer at 13799' MD. A 4 -1/2" kill string was left in the well from surface to 2227' MD. The well is mechanically sound as proven by a pressure test after the casing was cemented. 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, and 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 the Wellhead and Surface Location Niakuk well NK -11A is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. During the inspection, it was discovered the well sign was missing. A new sign has been ordered and will be placed at the well. The well pressure readings are T /1 /0 = NA/400/260. SteJ 4 Zoo r SL - 1Itoj/o Request !� o � !o•2Z•w BPXA requests approval for renewal of the existing suspension status for NK -11A. 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.

The well penetrated the Kuparuk reservoir and drilled approximately 325' of section before crossing the large Niakuk bounding fault and ending up in the Lisburne formation. As per Sundry #302-054, the well (now called NK-11 APB1) was plugged back and sidetracked to a Kuparuk target approximately 280' north of the initial Kuparuk penetration. Operations to complete the well at this new location were commenced and a 7" x 5W' tapered production liner was to be run and cemented. The liner was run into open hole without complication until encountering an obstruction at approximately 14,958' MD. While attempting to work past the obstruction, the liner running tool unexpectantly released leaving the liner approximately 2900' high of the planned set depth. After pulling the running tool from the hole it was discovered that several small pieces of the liner running tool were left downhole and that the liner top packer was potentially set. A fishing assembly including a spear and pack-off were then run in attempt to continue to work the liner downhole. This run confirmed that the liner top packer was set and that the liner was stuck atthis depth. Forward plans are to plug back the well and suspend operations. The reserves found at this location and the additional risks associated with the forward completion do not make this an economically attractive project. The well will be left in a condition that allows the potential for future sidetrack opportunities. Based upon information gathered from these two penetrations further reservoir evaluation is required to properly select an alternative sidetrack location. Below is an outline of the proposed plug back and suspension operations. Also enclosed is a schematic of the existing wellbore and proposed suspension condition. If you have any questions or require any additional information, please contact me at 564-5521. Scope Riq Operations: 1. RIH with 4-3/4" mill on 2-7/8" x 4" x 5" drillstring and drill out the 5-1/2" landing collar, float collar and shoe. POH. 2. RIH to TD at 17,867' MD with 2-7/8" x 4" x 5" DP cement stinger. Circulate and condition well for cementing operations. Spot a balanced 15.8 ppg cement P&A plug from TD to +/-16,500' MD (-500' above the Top Kuparuk Reservoir). Cement volume planned is 108 bbls and is based upon an equivalent hole diameter of 9.0" throughout this section. Pull above cement plug and circulate DP clean. NOTE: Plans are to wac only 2 hrs before spotting the heavy mud spacer. This will allow the cement to start an initial set and remain unaffected while spotting the spacer. The plug will not be tagged as long as it is placed on bottom at 17,867', and no losses are seen while spotting the plug or circulating on top of the plug. 3. Spot a 15.8 ppg heavy mud spacer from top of cement P&A plug at -16,500' MD to -14,800' MD. Pull DP up to 15,150' MD and circulate out any excess heavy mud spacer above this point.

Bill, Thanks for the e file and fax. I have reviewed your proposal and it is as we discussed. Bad news on liner problems, but unfortunately they do happen. What you have proposed will be acceptable for the suspension mode. When future plans are decided for this well, please note that if the original window is not reused, it will be necessary to shoot holes and effect a squeeze through the window interval. A suicide squeeze might be the best method for that situation, but the ultimate decision will be yours. Depending on your timing, you may wish to consider doing that at this time. Good luck.

Based on the drawings you sent and our discussion, you have approval to proceed as planned. Please have your rig supervisor keep close watch when setting the bottom plug to assure that returns are not lost. Your cement volume is well in excess of that necessary to cover the top of the Kuparuk. Provided there are not lost returns, it will not be necessary to tag the plug. Good luck.

These wells should not require well house removal and therefore, are not required to be shut-in for the NK-11A rig move. If for any reason the well house on either one of these wells needs to be removed, policy requires that the well be shut-in for the rig move. If shut-in is required, the wells will need to be shut-in at the surface and the SSSV. All surface flowlines and gas lift lines will be depressured to header pressure. Discuss the move at a pre-job safety meeting and designate a spotter to ensure there is no danger of a collision. > Heald Point Niakuk Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Recent H2S data from the pad is as follows: NK-11 Never Produced Adjacent producers at Surface: NK-09 20 ppm Aug 6, 01 NK-12B 0 ppm Aug 6, 01 NK-13 38 ppmJune 8, 00 (well is currently shut-in) NK-29 25 ppm Aug 6, 01 Adjacent producers at TD: NK-07 39 ppm Apr 02, 98 (well was shut-in 4th Quarter 1998) NK-07A 20 ppm Aug 6, 01 NK-27 25 ppm Aug 6, 01 The maximum recorded level of H2S on the pad was 60 ppm from NK-28 on June 15,2000.

Job 3: Run Whipstock Hazards and Contingencies ~ Once milling is complete, make sure all BOP equipment is operable. Wash out BOP stack to remove any metal cuttings which may have settled out. Job 7: Drillinq Intermediate/Production Hole Hazards and Contingencies ~ No fault crossings are planned in the drilling of NK-11A. As planned, the well bore will drill parallel to the large east/west-trending Niakuk fault with approximately 300' of separation at the Top Kuparuk Location and approximately 200' at TD. This fault will be south of the wellbore when entering the Kuparuk target and the target polygon should be adequately sized to assure this fault is avoided (it is critical that we stay within the south hard line). ~ 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 original NK-11 well was drilled with 9.1 to 9.2 ppg mud through the Ugnu and West Sak intervals. NK-11A Permit to Drill Page 5 r--- ~. >- The NK-11 A well path will drill full sections of the Tuffs and HRZ shales, and both 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 HRZ on the other hand has 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. >- The Kuparuk reservoir pressure is expected to be 4280 psi (8.9 ppg EMW) at the NK-11A bottom hole location. Because of the high mud weights required to drill the surrounding shale intervals, we will be drilling this interval with mud weights up to 10.9 ppg (-950 psi overbalance to Kuparuk). Based upon offset drilling data, losses are not expected, however monitor the well closely while drilling this interval and be prepared for potential losses by having fiberous LCM products on location. NK-62 encountered pressures as low as 3000 psi (RFT data) within the Kuparuk interval, and the well was successfully drilled without losses with mud weights of 10.6 ppg. >- Differential sticking will be a problem if the drill string is left stationary for an extended period of time across the long permeable sections of the Ugnu, West Sak and Kuparuk Sands. Minimize the time the pipe is left stationary. >- The kick tolerance for the 8W' open hole section would be 171 bbls assuming a kick from the Kuparuk at -16,896' MD. This is a worst case scenario based on an 9.3 ppg pore pressure gradient, a fracture gradient of 12.4 ppg at the 9-5/8" window, and 10.9 ppg mud in the hole. ~ Drilling Close Approach: All wells pass BP Close Approach guidelines, however there are several wells in close proximity and limit allowable deviation from the planned directional path. The nearest close approach well is NK-08A which is -268' well-to-well at 13,418' MD and passes under Major Risk rules. Note Anticollision Report for tolerance lines and allowable deviation from the planned NK-11 A well-path. _.....~=., ,,~"~....~w. ., .......=" mp... Job 9: Install 7" x 5%" Production Liner Ha~~sandConUngen~es >- Long shale intervals will be exposed while running the liner. Rotation of the liner may be necessary if downward progress is not possible. ~ Differential sticking is a major concern across the long Ugnu and West Sak sand intervals. The 10.9 ppg required for well bore stability of the HRZ will be substantially over balanced to these formations. Prior to running casing, hold a Pre-Job Safety Meeting to raise awareness of the high risk of differential sticking. Communicate individual responsibilities to all members of rig team and review connection I tripping practices to minimize the time the pipe is left stationary. ~ Ensure the liner top packer is set prior to POOH. This may require going through the setting process twice. Slack off with rotation to the maximum allowable down weight, as per Baker representative. .-~..,"~ ='.m~x' ,'. "','=.. =,-.,~w. ..>om.. ..
