Open hole window milling not to exceed 15'. J.Lau 12/16/25 TS 12/15/25 10-407 325-755 JLC 12/17/2025 12/18/25 To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz Drilling Engineer Date: December 10, 2025 Re:15-16C Sundry Request Sundry approval is requested to set a whipstock in the 15-16C wellbore as part of the drilling and completion of the proposed 15-16D CTD lateral. Proposed plan: Prior to drilling activities, E-line will set a 4-1/2" whipstock. Coil will mill window pre-rig. If unable to set the whipstock or mill the window pre-rig, the rig will perform that work. A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in and test BOPE. If unable to pre-rig, the rig will set the 4-1/2" whipstock and mill a single string 3.80" window + 10' of formation. The well will kick off drilling in the Ivishak Zone 2 and lands in Ivishak Zone 1. The lateral will continue in Zone 1 to TD. The proposed sidetrack will be completed with a 3-1/2"x3-1/4"x2-7/8 13Cr solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig). This completion will completely isolate and abandon the parent Prudhoe Pool perfs. 20 AAC 25.112(i) Variance Request: Hilcorp requests to plug the existing perforations via the liner cement job, packer whipstock and/or liner top packer, if the liner lap pressure test fails as an alternate plug placement.

The original toe perforations and added perfs from March ’18 and March ’20 are no longer competitive due to HGOR. The number of CIBPs stacked in liner should be kept at a minimum to ensure that the wellbore can be accessed when Gas Cap Water injection flooding makes it to DS-15. The LTP passed a drawdown test in ’22.In January ’23, CTU milled a plug and then set another plug uphole to all existing perfs then added 180’ of perfs in belly of lateral. These perfs where structurally higher than the toe perfs and ended up POP’ing above marginal GOR. The next target in heel is across a fault from the rest of lateral and located structurally lower in base of Z1A, which presents a much higher chance of success. Objective: First, CT will mill a CIBP. Next, CT shut off gas by setting a shallower CIBP above the existing HGOR perf intervals then add 180’ of perforations using the coiled tubing open-hole deployment system.Secondly, CT will mill a CIBP. Next, CT will shut off gas by setting a shallower CIBP above the existing HGOR perf intervals then add 375’ of Z1A perforations using the coiled tubing open-hole deployment system. Procedure: Coiled Tubing Part 1 1. Mill and recover 2-7/8” NS CIBP @ 15320’ MD. May use venturi burnshoe BHA or alternative per wellsite supervisor discretion. 2. Perform logging tie in run. Flag coil for CIBP 3. Confirm good log data. 4. RIH with 2-7/8” CIBP, kill well with 1% KCl then set plug @ 14780’ MD. Flag coil for perf run. 5. POOH and leave 60/40 cap in well to prevent freezing during open hole deployment. 6. Perform positive pressure test on LTP by pressuring up TBG to 1000 psi while all perfs are isolated. Monitor for 10 min. 7. Prep for open hole deployment 15-16C PTD:216-154 API: 50-029-21115-03-00 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 perfs 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 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. 8. 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. 9. Load will with 1% KCL/SW down TBG if needed.

At surface, prepare for deployment of TCP guns. 11. 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. 12. *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. 13.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.

The original toe perforations and added perfs from March ’18 and March ’20 are no longer competitive due to HGOR. The number of CIBPs stacked in liner should be kept at a minimum to ensure that the wellbore can be accessed when Gas Cap Water injection flooding makes it to DS-15. The LTP passed a drawdown test in ’22. Economics:Forecasting 225 IOR at a cost of $175 M. Objective: First, CT will mill a CIBP. Next, CT shut off gas by setting a shallower CIBP above the existing HGOR perf intervals then add 180’ of perforations using the coiled tubing open-hole deployment system. Procedure: Coiled Tubing 1. Mill and recover 2-7/8” NS CIBP @ 15320’ MD. May use venturi burnshoe BHA or alternative per wellsite supervisor discretion. 2. Perform logging tie in run. Flag coil for CIBP 3. Confirm good log data. 4. RIH with 2-7/8” CIBP, kill well with 1% KCl then set plug @ 14780’ MD. Flag coil for perf run. 5. POOH and leave 60/40 cap in well to prevent freezing during open hole deployment. 6. Perform positive pressure test on LTP by pressuring up TBG to 1000 psi while all perfs are isolated. Monitor for 10 min. 7. Prep for open hole deployment 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 perfs 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 MIRU service coil. PT PCE. MU MHA, Milling BHA and RIH. -00 DLB 15-16C PTD:216-154 API: 500292111503 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. 8. 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. 9. Load will with 1% KCL/SW down TBG if needed. Max tubing pressure 2500 psi. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.) a. Wellbore volume to top perf = 209 bbls i. 4-1/2” Tubing – 12791’ X 0.0152 bpf = 195 bbls ii. 3-1/2” and 3-1/4” Liner – 481’ X 0.0087 bpf + 509’ X 0.0079 bpf = 8 bbls iii. 2-7/8” Liner – 1069’ X 0.0058 bpf = 6 bbls b. 13Cr80 TBG from surface to TBG tail at 12228’ MD 10. At surface, prepare for deployment of TCP guns. 11. 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. 12.*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. 13.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. Perf Schedule *2" Millennium guns were used to estimate for this job and calculate gun weights. Perf Interval (RUN 1) Perf Length Gun Length Weight of Gun (lbs) 5.58 lbs/ft 14500 - 14680 180’180’1005 14. RIH with perf guns and tie-in to coil flag. Pickup and perforate interval per Perf Schedule above. a. Note any tubing pressure change in WSR. 15. After perforating, PUH to top of liner or into tubing tail to ensure debris doesn’t fall in on the guns and stick the BHA. Confirm well is dead and re-kill if necessary, before pulling to surface. 16. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 17. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 18.
