Proposed plan: See B-04A Sundry request for complete pre-rig details - Prior to drilling activities, coil will mill two CBPs and push to bottom, slickline will drift for a whipstock, and E-line will set a 3-1/4" 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 CDR3 rig. The rig will move in, test BOPE and kill the well. If unable to pre-rig, the rig will set the 3-1/4" whipstock and mill a single string 3.80" window + 10' of formation. The well will kick off drilling in Ivishak Zone 4. The lateral will land and continue in Zone 2 to TD. The proposed sidetrack will be completed with a 2-3/8” 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 following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference. Pre-Rig Work: (Estimated to start in 9/15/2025) 1. Coil : Mill CBPs at 10,130' and 10,205' and push to bottom. 2. Slickline : Whipstock Drift/DMY GLVs 3. E-line : Set 3-1/4" Packer Whipstock at 10,341' MD @ 0 deg RHOS 4. Coil : Mill 2.74" Window 5. Valve Shop : Pre-CTD Tree Work 6. Operations : Remove wellhouse and level pad. Rig Work: (Estimated to start in October 2025) x Reference B-04B Permit submitted in concert with this request for full details. 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,420 psi). Give AOGCC 24hr notice prior to BOPE test. 2. Mill 2.74” Window (if not done pre-rig). 3. Drill build section: 3.25" OH, ~483' (31 deg DLS planned). 4. Drill production lateral: 3.25" OH, ~1729' (12 deg DLS planned). Swap to KWF for liner. 5. Run 2-3/8” 13Cr solid liner 6. Pump primary cement job*: 15 bbls, 15.3 ppg Class G, 1.24 (ft3/sk), TOC at window. If high losses are encountered during cement job and it is deemed necessary, a cement down squeeze from TOL to loss zone will be performed with the rig or service coil (if performed by service coil see future sundry). 7. Only if not able to do with service coil extended perf post rig – Perforate Liner 8. Freeze protect well to a min 2,200' TVD. ,p yp This completion will completely isolate and abandon thepg( p parent Prudhoe Pool perfs. Max 15' of open hole - JJL 9. Close in tree, RDMO. * Alternate plug placement variance request per 20 AAC 25.112(i) Post Rig Work: 1. Valve Shop : Valve & tree work 2. Service Coil : Post rig RPM and perforate (~30’) 3.

Terrie Hubble,564-4628 Well Number Permit No./Approval No. Drilling Engineer: Sean McLaughlin,564-4387 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item la: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 MC 25.071.

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.

(3) All True Vertical Depths (TVDSS) are SubSea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well . . (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole weight on Bit) , a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a Primary Depth Control (PDC) log from well E-09C above the Kick off Point of 11090 ft. MD dated 18 Nov 2009 per Doug Stoner with BP Exploration (Alaska) , Inc. (8) The sidetrack was drilled from E-09 through a milled window in a 3 3/16 inch liner. Top of window 10613 ft.MD (8635.2 ft.TVDSS) Bottom of window 10619 ft.MD (8639.7 ft.TVDSS) (9) Tied to E-09 at 10612 feet MD (8494.0 feet TVDSS) . (10) The interval from 11988 ft to 12020 ft MD (8883.0 ft. to 8886.9 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
