From:Rixse, Melvin G (OGC) To:Erik Nelson Subject:20250912 1646 APPROVAL Request for liighter fluids to prevent losses PTD 190-055 Sundry 325-553 Date:Friday, September 12, 2025 4:48:18 PM Attachments:image001.png image002.png Erik, Thanks for the note. Sounds like you are zeroing in on your actual pore pressures. Hilcorp is approved to proceed as you described below.

Mel, Very much appreciate the AOGCC turning around our 10-403 COP for MPU H-03. I have noted the AOGCC’s COA on Approved Sundry# 325-553 and have changed the Subject line on this email chain. As we have been preparing for our 2nd TCP run we’ve been monitoring the fluid level in the well and have determined that, with 8.7 #/gal in the hole, our fluid level has remained unchanged at +/- 114-ft MD. This fluid level calculates out to a reservoir pressure of 957 psi (8.28 #/gal equivalent) at our top perforation at 2500-ft MD (2230-ft TVD). Our analysis of offset well data previously anticipated the formation pressure to be 996 psi (8.59 #/gal equivalent) at that depth which we used to anticipate our planned fluid weights for the workover. Given this recently acquired information we would like to change our fluid weight during our perf surge and cleanout runs to as low as 8.5 #/gal rather than the 8.7 #/gal that was stated, and thus Approved, in our latest Application for Sundry Approval. We plan on taking it down to 8.6 #/gal initially to see if we can maintain returns while circulating but we are requesting approval to take it as low as 8.5 #/gal. The 8.7 #/gal fluid weight is specified in the following Steps with Approved Sundry# 325-553: CAUTION: External sender. DO NOT open links or attachments from UNKNOWN senders. 58. Reverse circulating from +/- 2270-ft MD after allowing the formation to surge up the dry tbg string 66. Displacement of wellbore after cleaning out to the sump packer (3213-ft MD) 78. c) i) This step is displacement of the tbg pickle in preparation for pumping the gravel pack 79. We were already planning to pump the gravel pack with freshwater but the procedure calls for circulating around the heavier fluid before we TOOH We believe this change in fluid weights will help us minimize our fluid losses to the formation while still maintaining appropriate primary well control with our workover fluid. Thank you for your time and consideration of our request. Please let me know if you have any questions and or require any additional information.

Mel From: Erik Nelson <erik.nelson@hilcorp.com> Sent: Thursday, September 11, 2025 11:43 AM To: Rixse, Melvin G (OGC) <melvin.rixse@alaska.gov> Subject: RE: [EXTERNAL] 20250909 1608 APPROVAL Request for Verbal Approval of COP on MPU H-03 (PTD# 190-088) operating under Approved Sundry# 325-487... Mel, I’ve submitted a 10-403 COP today for MPU H-03. This COP will include the changes to the Approved Sundry that were authorized below as well as a request to approve a perf surge run after we get our TCP gun runs completed. After that perf surge run we should be back on our original Approved Sundry but I did make the changes to the final completion that were adjusted due to the changes in the sump packer set depth and perforation intervals. st nd CAUTION: This email originated from outside the State of Alaska mail system. Do not click links or open attachments unless you recognize the sender and know the content is safe. CAUTION: External sender. DO NOT open links or attachments from UNKNOWN senders. We’re currently running in with our 1 TCP gun run which will be followed by a 2 TCP gun run. I’m forecasting we will be ready to make our perf surge run tomorrow evening. Thank you for your time and consideration of my request. Please let me know if you’ve got any questions and/or comments.

Mel, We got our E-Line logging done last night and received the processed logs this afternoon on MPU H-03. The Tertiary Undef WTRSP (525130) aquifer came in a little different than our correlations from offset well logs. We are proposing the below new perforations in our pursuit of turning MPU H-03 into a WSW: New Proposed Perfs: Currently Approved Perfs: In our currently approved Sundry# 325-487 we proposed setting our sump pkr at +/- 3295-ft MD (2793-ft TVD). Due to the adjustments in the perforations I would like to set it at +/- 3213-ft MD (2733-ft MD). I am prepping a 10-403 COP but we will be running the sump pkr this evening so I am requesting verbal permission to proceed. Q Erik Q.

Michael Jackson Subject: S-24Ai Application for Sundry Permit The S-24Ai sidetrack is currently scheduled for Nabors 22E following the completion of S-11Ai. * Notify the field AOGCC representative with intent to plug and abandon * Pre-Riq Work: Perform a cement P&A of 15.8 ppg class 'G' cement with adequate cement volume to cover the 7" liner from PBTD at 10,385' to a minimum of 100' above the top perforation at 9834' plus squeeze 5 bbls to the perforations. Estimated cement volume needed is 30 barrels. A full bore P&A is recommended but is at the discretion of the Wells Group. There are no GLM's in the completion string. Note: Top of cement must be at a minimum of 9734' for AOGCC compliance. Top of cement may extend into the tubing as long as it does not interfere with the tubing cutting operations. 2. Rig up slickline, tag and document top of cement. 3. Cut the 4 1/2" L-80 tubing in the middle of a full joint of tubing at 4500'. This cut will not be fished and is at the discretion of the Wells Group as to chemical or jet cut. 4. Test the McEvoy 9-5/8" mandrel packoff and tubing hanger seals to 5000 psi for 30 minutes. 5. Test the casing against the cement plug to 3000 psi for 30 minutes. Freeze protect top 2200' MD with diesel. Ensure the cut is successful and communication exists between casing/tubing to avoid tubing collapse. 6. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 7. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Ri.q Operations: 10. 1. MIRU Nabors 7ES 2. Circulate out freeze protection. Set TWC. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull 4-1/2" tubing. 5. Make up an 8.5" bridge plug on drill pipe and set at 4100'. 6. Weight test the bridge plug and pressure test the casing to 4000 psi for 30 minutes(injection well). 7. Displace the well to milling fluid and spot a 18 ppg pill from the bridge plug to the milled section. 8. RIH with 9-5/8" Baker section mill assembly and mill a 50' window from 3800' to 3850'. 9. RIH with a mule shoe to 100' below the base of the section and spot a 17 ppg balanced cement plug from 100' below the section to 200' above the section. Kick-off drilling the 8-1/2" intermediate section to TSag @ _+10,460' md(8663' TVD). Run and cement a 7", 26# intermediate liner with a minimum of 150' liner lap in the 9-5/8". Test the 7" and the 9-5/8" casing from the 7" landing collar to surface to 4000 psi for 30 minutes. 13. 14. 15, 16. 17. 18. 19. 20. 21. 22. 23. Drill the 6" production section building to horizontal targeting the Zone 4 sands(8813' TVD) to an estimated depth of 1,858' md(8993' TVD). Run DPC 'Platform Express' + Sonic logs from horizontal to 7" shoe· Run and fully cement a 4-1/2", 12.6# production liner with a minimum of 150' liner lap in the 7". Run a USIT / CBT on e-line as deep as possible logging the 4·5" and 7" cement bond for 1000' above the top of the 4·5" liner· Test the 4-1/2", 7" and 9-5/8" casing from the 4-1/2" landing collar to surface to 4000 psi for 30 minutes· The 4-1/2" production liner will be perforated with DPC 2.75" guns on a 400 psi under balance. Perforating intervals to be determined after reviewing logs. Run 4-1/2" NSCT L-80 completion tying into the 4-1/2" liner. Test the tubing to 4000 psi and annulus to 4000 psi for 30 minutes with 2500 psi on the tubing. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. Freeze protect the well to -2200' and secure the well. Rig down and move off.

Until a recent failed MIT for injection service there was no indication of problems with the installation. A subsequent leak detection survey verified that the top sealing portion of the patch had failed. A variance is being requested for the well to remain on seawater injection only while a problem of this same nature is fixed on well S-05 (see attached request). After the success or failure of the S-05 job, a job of the same nature or a RWO for well S-24 will be pursued prior to placing the well on MI injection. lip EXI~,OP, J~'ION Mem=rlndum To: M. Townsend/E. Walker Date: 8/23/94 P.B. Production Engineering Supervisor L. Seymour~/l~~ W.F./M.I. FIo'b~FSDp~rvi,~r-' - '"'- From: Subject: S-05 Repeata "B" Patch Fix A patch from 9501' to 9526' WLMD across GLM #1 of this well is currently leaking. A thorough review of video of the patch and a leak detection Icg have determined that the patch did not set properly as the upper swedge did not Seat. Because the metal in the existing patch could be fiowcut, attempting to seat the swedge is not viewed as a solution to the problem. The best approach is viewed to be setting the retrievable top portion of a Repeata "B" patch across the top of the existing patch, The Repeata "B" would have an internal fishing neck like that on a 51/2" plug and would stab into and seat on top of current patch. It would have a 2.66" ID with external "V" packing at the bottom that would seal against the ID of the current patch. Paul Russell is the contact at HES and is up to speed on the job. This work is expected to cost approximately $25M. Other current alternatives are in the $200M + range. It is currently felt that large expenditures are not justifiable at this time. This request supercedes a prior request in February to attempt to pull the patch. Please direct any comments or questions to Greg Hobbs at extn. 4191 or at home (696- 3036).
