Wilson Date: 2025.08.20 10:10:27 -08'00'08/20/25 RBDMS JSB 082225 To: Alaska Oil & Gas Conservation Commission From: Trevor Hyatt Drilling Engineer Date: August 7, 2025 Re:S-110B Sundry Request Sundry approval is requested to mill out of the existing shoe in the S-110B wellbore as part of the drilling and completion of the proposed S-110C CTD lateral. Proposed plan: Prior to drilling activities, screening will be conducted to drift/caliper and MIT. E-line or coil will mill the XN-nipple. Coil will mill out of slotted liner shoe pre-rig. If unable to set mill out slotted liner shoe pre-rig, the rig will perform that work. See S-110C 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. If unable to pre-rig, the rig will mill out of the slotted liner shoe with a 3.80" mill + 10' of formation. The well will kick off drilling and lands in the Kuparuk C. The lateral will continue in Kuparuk C, B and A to TD. The proposed sidetrack will be completed with a 3- 1/2"x3-1/4"x2-7/8” L-80 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 Aurora Pool slotted liner. 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 September 2025) 1. Slickline : Dummy WS drift and Caliper 2. Fullbore : MIT-IA and/or MIT-T to 3,100 psi (min) 3. Coil : Mill XN nipple (at 8,578' MD) and mill out slotted liner shoe with 3.80" mill plus 10' rat hole. 4. Valve Shop : Pre-CTD Tree Work 5. Operations : Remove wellhouse and level pad. Rig Work: x Reference S-110C Permit submitted in concert with this request for full details. 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,988 psi). Give AOGCC 24hr notice prior to BOPE test. 2. Mill 3.80” out of slotted liner shoe (if not already done pre-rig) 3. Drill build section: 4.25" OH, ~117' (38 deg DLS planned). 4. Drill production lateral: 4.25" OH, ~2,781' (12 deg DLS planned). Swap to KWF for liner. 5. Run 3-1/2” x 3-1/4” x 2-7/8” L-80 solid liner (swap to VBRs and test prior to running liner) 6. Pump primary cement job*: 38 bbls, 15.3 ppg Class G, 1.24 (ft3/sk), TOC at TOL. Set LTP*. 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. 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. Slickline : Contingent set LTP.

Dear Mr. Rixse, 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 02/09/2024. 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.
