Post Office Box 244027 Anchorage, AK 99524-4027 3800 Centerpoint Drive Suite 1400 Anchorage, AK 99503 Phone: (907) 564-4891 06/09/2025 Mr. Jack Lau Alaska Oil and Gas Conservation Commission 333 West 7th Avenue, Suite 100 Anchorage, Alaska 99501 Re: Prudhoe Bay Surface Casing by Conductor Annulus Top-offs of Cement, Corrosion Inhibitor through 06/09/2025. Dear Mr. Lau, 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 06/09/2025. 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.

This grassroots well is a slant injector well targeting the Ugnu formation. The planned well is a two string, big bore well utilizing 13-3/8" surface casing and 9-5/8" production casing. This will be followed by a 5-1/2" x 7" tubing string.The surface casing will be set in the SV4 shale and the production casing will be set in the WS1. The maximum anticipated surface pressure from the WS1 with a full column of gas from TO to surface is 2,216 psi (assumes 8.87 ppg EMW most likely pore pressure and a 0.10 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 4,000 psi. A detailed operations summary is included with the permit application. If there are any questions concerning information on PWDW3-2, please do not hesitate to use the contact information below.

Drilling Waste Disposal • There is no annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS -04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS -04 for injection. Haul Class I waste to DS -04 and/or Pad 3 for disposal. Contact the GPB Environmental Advisors (659-5893) for guidance. PWDW3-2 PTD 5 5/22/2019 Well Control The 16" surface hole will be drilled with a diverter (see attached diverter layout). The 12-1/4" hole hole section will be drilled with well control equipment consisting of 5,000 psi working pressure rams (2), blind/shear rams, and annular preventer capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 4,000 psi. BOP test frequency for PWDW3-2 will be 14 days with function test every 7 days. Except in the event of a significant operational issue that may affect well integrity or pose safety concerns, an extension to the 14 day BOP test period should not be requested. 12-1/4" Production Interval Maximum anticipated BHP 2,830 psi at the WS1 at 6,135' TVDss 8.87 ppq EM Maximum surface pressure 2,216 psi at the WS1 (0.10 psi/ft gas gradient to surface) 25 bbls with 11.60 ppg frac gradient.

(GRASSROOTS)To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line (<1000 ft). This is a variance from 20 AAC 25.033. Procedures/Safeguards with paddle removed: • Fluid levels will be monitored in the pits for both gains and losses while drilling. Alarms will be set to indicate if gain or loss of more than 10 bbls has occurred. • The well will be monitored for flow when the pumps are off at each connection. • The planned 8.5 — 9.6 ppg fluid will provide over balance to formation fluid.

In this particular scenario it is not necessary to utilize a 9.8 ppg brine as the highest PP formation we are opening is 9.39 ppg EMW. The 9.5 ppg brine will be circulated out and corrosion inhibited fluids will be circulated during the post well work which will mitigate any risk of freezing. As far as the 500' of brine is concerned, this was also a typo, a non -freezable fluid will be placed across the entire permafrost interval. As for your area of review question, the well in question should be PWDW3-1 the original well that the PWDW3-2 is going to replace. Thanks, Brad Gorham BP Exploration (Alaska), Inc.
