Chmielowski Date: 2025.04.07 15:16:40 -08'00'04/07/25 RBDMS JSB 040825 To: Alaska Oil & Gas Conservation Commission From: Trevor Hyatt Drilling Engineer Date: March 28, 2025 Re:18-27E Sundry Request Sundry approval is requested to set a whipstock and mill a window in the 18-27E wellbore as part of the drilling and completion of the proposed 18-27F CTD lateral. Proposed plan for 18-27F Producer: Prior to drilling activities, screening will be conducted to MIT. The existing 3-1/2" liner will be cut with E-line and verified it is free (and ready to be pulled by rig) with service coil. See 18-27F PTD request for complete drilling details - A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in, test BOPE and kill the well. The rig will latch up to the 3-1/2" pre- cut liner and pull out of hole. A whipstock drift will be performed followed by setting a 4-1/2" packer whipstock. A dual string 3.80" window + 10' of formation will be milled out of the 4-1/2" and 7" liners. The well will kick off drilling in the Ivishak Zone 2 and lands in 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 not completely isolate and abandon the parent Prudhoe Pool perfs (Sag perfs will remain open). 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 following describes the work planned. A wellbore schematic of the current well and proposed sidetrack is attached for reference. Pre-Rig Work: (Estimated to start April 2025) x Reference 18-27E Sundry submitted in concert with this request for full details. 1. E-Line : Cut 3-1/2" coil at 9,610' MD 2. Fullbore : MIT-IA and/or MIT-T to 2,500 psi 3. Slickline : Bait deployment sleeve for service coil 4. Coil : Latch liner and pick up, verify liner free. Set down and release. 5. Valve Shop : Pre-CTD Tree Work 6. Operations : Remove wellhouse and level pad. Rig Work: 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,460 psi). Give AOGCC 24hr notice prior to BOPE test (install VBRs for pulling liner) 2. Pull 3-1/2" pre-cut liner from 9,610' MD and lay down 3. Drift for whipstock (swap to 3” pressure deployment rams and test) 4. Set 4-1/2" Packer Whipstock* at 9,550’ MD at 180 degrees ROHS 5. Mill 3.80” Window 6. Drill build section: 4.25" OH, ~379' (28 deg DLS planned). 7. Drill production lateral: 4.25" OH, ~1850' (12 deg DLS planned). Swap to KWF for liner. 8. Run 3-1/2” x 3-1/4” x 2-7/8” 13Cr solid liner (swap to VBRs and test prior to running liner) 9. Pump primary cement job: 32 bbls, 15.3 ppg Class G, 1.24 (ft3/sk), TOC at TOL.* 10. Only if not able to do with service coil extended perf post rig – Perforate Liner 11. Freeze protect well to a min 2,200' TVD. 12. Close in tree, RDMO. * Alternate plug placement variance request per 20 AAC 25.112(i) py completion will not completely isolate andppg(p g pg) abandon the parent Prudhoe Pool perfs (Sag perfs will remain open) Post Rig Work: 1. Valve Shop : Valve & tree work 2. Slickline : Set LTP* (if necessary). Set live GLVs. 3. Service Coil : Perforate (~1250’) - see extended perf procedure attached. 4. Testing : Portable test separator flowback.

Later in 1998, 2000, 2005 and 2012 it was coil sidetracked to the current bottom hole location. In Feb 2016 the toe perfs were isolated and Z1A heel perfs were added with great result. The well produced until 2020 when a tubing leak was identified. A caliper indicated it is not worth patching. We will now pursue a RWO to replace the L-80 tubing. Objective: Pull the existing 4 ½” L80 tubing out of the well and replace with 13 chrome tubing. Achieve a passing MIT-IA & MIT-T.

I. Supervisor FROM: Guy Cook SUBJECT: BOPE Test — VBR Test Failure Petroleum Inspector PBU 18-27E , Thunderbird Rig 1 Hilcorp North Slope LLC. PTD 2121310;-Sundry321-181 6/26/2021: Arrived at location and spoke with the Company Representative Jay Murphy about the failed 2 7/8" tests on their last BOP test on 6/24/21. They had two failures with two different 2 7/8" x 5 '/2" VBRs. The rams tested on the 4 '/2" test joint so they left in the VBRs and moved forward planning to test the 2 7/8" again after pulling the 4 '/2" tubing out of the well. Once they were ready, testing started. The hydraulic pressure on the rams currently was 1700 psi. The first attempt to get a 250 -psi low pressure test failed. There was a leaking needle valve that was part of the issue, but at the time was assumed it was the only leak. On the second attempt to get a good 250 psi low test, the leak was still present so it was decided to bump up the hydraulic control pressure on the ram to see if the VBRs would seal. The control pressure was increased to 1900 psi. The pressure on the VBRs was bumped back up to 300 psi and got a good five-minute low test. Then proceeded up to 3200 psi for the high test and the VBRs leaked immediately and the pressure fell off rapidly. The pressure was bled to zero and the hydraulic control pressure on the rams was increased to 2200 psi, proceeded to the high-pressure test and the pressure continued to bleed off. It was decided by Jay Murphy that the VBRs would be removed and a set of 2 7/8" solid rams would be installed. He told me this same issue had happened on the last well (PBU Z-11) and that this is how they were able to proceed. I left location but instructed Mr. Murphy to send me a picture of the chart after they test the 2 7/8" solid rams, before they proceeded with the workover.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 4.25" 11,290' and— 13,185' and 3.75" /cy'zv /3/f3 Liner Program: Solid, cemented, and perforated completion. • 3-1/4 TCII x 2-7/8" STL liner, 10,700' and — 13185' md. • Planned 23 bbls of 15.8 class G cement will be used for liner cementing (assuming 4.25" hole size to 10,800 and 3.75" hole to TD and 20% excess in open hole). TOC planned at 9,600 MD. • 3-1/2" tie back liner and LTP ran to 8670 to isolate the Put River perfs. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in the hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and a minimum of 3500 psi. Directional • See attached directional plan. Maximum planned hole angle is 91°, inclination at kick off point is 86.6°. • • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—27,000 ft. • Distance to nearest well within pool— 1,000 from 18-31A. Anti-Collision • No anti-collision issues Logging • MWD directional, Gamma Ray and Resistivity logs will be run in the horizontal hole section. • Cased hole GR/CCL/MCNL logs will be run. Perforating • SWS 1.56", 6 spf, perf guns • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in the hole. Hazards • Drillsite 18 is not considered H2S drillsite. Reservoir Pressure • The reservoir pressure on 18-27E is expected to be 3,294 psi at 8,800' TVDss (7.2 ppg equivalent) • Max expected surface pressure with gas (0.10 psi/ft) to surface is 2,414 psi. • A EMW of 8.4 ppg for this well will provide —549 psi over-balance to the reservoir- Ivishak. • A EMW of 8.4 ppg for this well will provide —685 psi over-balance to the reservoir— Put River.
