Dear Mr. Lau, Enclosed please find a copy of a spreadsheet with a list of Prudhoe Bay wells that were topped-off with cement, corrosion inhibitor in the surface casing by conductor annulus through 06/09/2025. Cement top-offs are executed as needed to mitigate the void space left at surface by minor cement fallback during the primary surface casing by conductor cement job. The remaining void space between the top of the cement and the top of the conductor is filled with a heavier than water corrosion inhibitor to reduce the risk of external surface casing corrosion. The attached spreadsheets include the well names, API and PTD numbers, treatment dates and volumes. 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 have any additional questions, please contact me at 564-4891 or oliver.sternicki@hilcorp.com.

MPSP:2320 psi (BHP - .1psi/ft gas gradient) Max Dev:94 deg @ 11,040’ MD Min ID:1.81” ID 45KB LTP at 8,542’ MD Brief Well Summary: F-10C is currently a cycle well at F-Pad. The well had a mill plug job done in 2021 that is now played out, so we would like to isolate the lower three perf stages. New perforations will be shot that will be commingled with the upper two perf sets. The upper perfs are thought to be low productivity and low gas rate. There is potentially some CIBP/retainer debris at the LTP that will need to be removed before the CIBP/add perfs can be executed. Objective: The purpose of this procedure is to isolate all perforations below 11250’ MD and add ~240’ of uphole perforations using extended perforation deployment. NOTES: x In July 2021, after an IA cement job, CT milled and pushed a retainer and CIBP to the LTP. They were not able to recover all debris. A dream catcher was set on 7/21/23 and pulled on 8/25/21. The catcher recovered chunk of mesh, milled cement retainer, and several small pieced of metal. The dreamcatcher was reset and pulled on 11/6/22. Additional CBP debris was recovered. A third dreamcatcher was set on 11/7/22. On 12/26/22, the dreamcatcher was pulled and recovered multiple slips from the CIBP. The dreamcatcher was reset and on 2/28/23 it was pulled with no debris inside the catcher. There is currently a dreamcatcher in the hole. It is unknown how much (if any) debris is remaining at the LTP. x Needs 1.5” CT. Procedure: Slickline: 1.Pull dreamcatcher. 2.Drift to deviation for 2-3/8” CIBP (1.75”) to confirm LTP is free of CBP debris. If debris is encountered, attempt to recover. The goal is to create a clear path for coil through the LTP. Coil Notes: x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. x The well will be killed and monitored before making up the initial perf guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after o isolate all perforations below 11250’ MD and add ~240’ of uphole perforations using extended perforation deployment. CIBP & Ext AdPerf Well: F-10C perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. 1. MIRU 1.5” CTU 2. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through the brass upon POOH with guns. 3. Review pre-coil SL drift AWGRS. There is potentially CIBP/retainer debris at the LTP. If debris was found by SL and not able to be recovered, attempt to recover. We would like to maintain LTP integrity, so be conservative with recovery method. 4. RIH with GR/CCL & 1.8” nozzle to ~11,250’. PUH and paint flag for plug/perfs depths. 5. POOH. 6. Bullhead ~207 bbls 1% KCL/SW down tubing. Max tubing pressure 2500 psi. (This step can be performed any time before prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.Recommended to complete well kill prior to setting CIBP as we believe the perforations above 11250’ MD are low productivity.) a. Wellbore volume to top perf = 138 bbls b. 4-1/2” Tubing – 8534’ X 0.0232bpf = 130 bbls c. 2-3/8” Liner – 12032’ X 0.0039 = 47 bbl 7. MU 2-3/8” CIBP. RIH and set at ~11,200’. a. Tag CIBP to confirm good set. b. Adjust plug depth slightly at WSL discretion. CIBP was previously set at 11,100’ MD. Avoid setting at collars and previous plug depth. 8. POOH. Prepare for deployment of TCP guns. 9. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain hole fill taking returns to tank until lubricator connection is re-established. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 10.*Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. a.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 11.Break lubricator connection at QTS and begin makeup of TCP guns per schedule below. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow.

A Sundry for repairing the SH leak was submitted and approved (Sundry # 320-299) on July 22, 2020. In the course of preparing for the SH weld the tubing and IA were loaded with crude and a failing CMIT TxIA was performed. A LLR of ~0.5 BPM @ 600 psi was established during a subsequent LDL which indicated a PC leak ~5720’ MD. An MITT passed to 2500 psi on 08/07/2019. Status Currently classified as Not Operable by Hilcorp due to the starting head leak and PC leak. Objective Repair the well with an IA cement job followed by a SH leak weld (separate Sundry) that is estimated to provide an incremental 250 MBO of production over the next several years. Without an IA cement repair the well has no utility in the foreseeable future. The proposed TOC the IA is ~4150’ MD which is ~1500’ TVD below the SC shoe and ~210’ shallower than the estimated top of the UG4 marker @ ~4360’ MD. This TOC will cover the PC leak at ~5720’ MD and will meet the regulatory requirements of CO 736. Post-job Evaluation o MIT-T and CMIT-TxIA o SCMT to confirm the Top of Cement (TOC) Long-Term Integrity Monitoring o Biennial MIT-T and CMIT-TxIA o Monitor and Record WHPs daily 2 Procedural steps Slickline 1. Pull Tubing Tail Plug. E-Line & Fullbore 1. Set 4-1/2” CBP just above the production packer. 2. PT of tubing/CBP to 1500 psi to verify CBP set. Five minute test, no more than 10% pressure loss. 3. Punch tubing in the middle of the first collar above the CBP. 4. Pump diesel down the tubing while taking returns up the IA, to confirm circulating rates and pressures through tubing punch. Circulate tubing and IA to diesel. 5. Set 4-1/2” cement retainer in the joint of tubing above the tubing punch. Fullbore (This step may be performed with CT as well but will not include the wiper/displacement balls in that case as the CT will be stung into the retainer) 1. Pumping down Tubing, establish returns up the IA and pump the following schedule: ¾~230 bbls 15.8 ppg Class G cement ¾Drop Retainer-ball, Foam-ball ¾FW spacer ¾~205 bbls diesel ¾Bump ball on retainer with ~500 psi excess. Slickline & Fullbore 1. Break-up cement retainer. 2. Log Memory SCMT from ~8450’ MD to surface to identify TOC. 3. Conduct AOGCC witnessed MIT-T and CMIT-TxIA to 1500 psi. Ensure 24-hour notice provided for AOGCC. 4. Break up cement and CBP and push remnants out tubing tail. Well Diagnostics & WIE 1. Update AKIMS and add biennial MIT-T & CMIT-TxIA Cement Calculations ¾9-5/8” x 4-1/2” volume from 4150’ – 8450’ MD: 230 BBLS CBL data to AOGCC. 3 Production Casing Leak @ ~5720’ MD 4 F-10 Proposed TOC in IA ~4150’MD 5 F-10 Proposed P&A Reservoir Cement Plug Surface Cement Plug Operator Name:2.
