Post Office Box 244027 Anchorage, AK 99524-4027 3800 Centerpoint Drive Suite 1400 Anchorage, AK 99503 Phone: (907) 564-4891 02/09/2024 Mr. Mel Rixse 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 02/09/2024. 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.

Honas, ODE Date: June 5, 2012 Re: Z-69 Permit to Drill The Z-69 well is currently scheduled to be drilled by Doyon 25 September 2012. The grassroots well is a slant producer targeting the Ivishak Zone 41hrough Zone 2 North of Z -pad. The well builds to the South through the surface hole prior to changing direction to avoid free gas on the North side of the Highland State Fault. This allows the well to remain a three string Ultra Slim Hole design. The production interval drills through the Sag River and Ivishak formations and will be a simple perforated chrome liner. Approximately 100 ft of perforations are anticipated. The maximum anticipated surface pressure from the Ivishak/Sag with a full column of gas from TD to surface is 2877 psi (assumes 8.48 ppg as max pore pressure). This well will be drilled by Doyon 25 using their 5000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 3500 psi. . A detailed operations summary is included with the permit application. Below is a brief summary of planned drilling operations: 1. Move in Doyon 25 and function test diverter. 2. Drill 12-1/4" surface hole to 3284 ft MD. 3. Run 9-5/8" surface casing and cement to surface. 4. Nipple up BOPE and test. 5. Pressure test surface casing. Drill out the shoe and perform LOT. 6. Drill 8-3/4" intermediate hole to top of the reservoir at 10,282 ft MD. 7. Run 7" casing and cement to —500 ft TVD above the SB_Na top. 8. Drill out of intermediate shoe and perform FIT. 9. Drill 6-1/8" horizontal production hole through Zone 4 of the Ivishak to TD at 11,021 ft MD. 10. Obtain open hole sonic logs on wireline. 11. Run a cement bond- log and obtain shear/compressional sonic data over the 7" intermediate casing on wireline. 12. Make a cleanout run in the 6-1/8" production hole. 13. Run and fully cement a 4-1/2" chrome production liner. 14. Run drill pipe conveyed perforating guns. 15. Run 4-1/2" completion tubing. Sting into liner tieback sleeve and set production packer. 16. Pressure test the tubing and the inner annulus. 17. Rig down and move off the well. In addition to a planned well summary, a directional plan and proposed completion diagram is attached to the permit application.

After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line (<1000'). 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 5 bbls has occurred. • The well will be monitored for flow when the pumps are off at each connection. v, / Over 50 surface holes have been drilled on Z -pad, including the recent Z-40 and Z-50 wells in 2012, providing a high level of confidence in the ability to drill surface hole on the pad without incident. • The planned 8.8 - 9.4 ppg fluid will provide over balance to formation fluid.

Z-69 PTD Page 10 6/5/2012 Z-69 Drilling Critical Issues POST THIS NOTICE IN THE DOGHOUSE 1. Well Control / Reservoir Pressures: A. Surface Hole: No overpressure is expected in the surface hole and hydrates have been a minimal concern in this area of the pad. It is critical that the wellpath build to the South and remain South of the hardline at 3015 ft TVDss. This will ensure "free -gas" is not encountered while drilling on diverter. B. Intermediate Hole: Expect up to 10.0 ppg overpressure in the Colville starting at 5900 ft TVDss. The. Mud weight must be increased to a minimum of 10.2 ppg prior to drilling the Colville overpressure. C. Production Hole: The highest anticipated pore pressure in the production hole will be encountered in the Sag River at 8.48 ppg. The interval will be drilled with a minimum of 8.7 ppg drilling fluid to provide adequate trip margin. II. Lost Circulation/Breathing A. Surface Hole: Lost circulation is considered a minimal risk if mud properties remain in specification. B. Intermediate Hole: Breathing and/or lost circulation is a possibility due to 4 fault crossings. Breathing is also common in the Colville. The wellbore has been designed with a maximum mud weight of 10.4 ppg for over balance and wellbore stability. 10.5 ppg has historically been considered low enough to help prevent losses and breathing, however, ECD must be carefully managed to further reduce the risk. The Kuparuk C sands are depleted to 6.7 ppg. Drilling with a 10.2-10.4ppg drilling fluid increases risk of lost circulation into these sands. C. Production Hole: No fault crossings are planned in this section however the production hole drills parallel between two fault plains which increases risk for lost circulation. When drilling to 8620 ft TVDss ensure the wellpath is within the upper driller's polygon. Additionally at 9100 ft TVDss ensure the wellpath is within the lower driller's polygon. This will ensure maximum offset from the faults. Be prepared for breathing in the Shublik if fractures exist in the area. This has been an occasional problem across Prudhoe, but is considered a low risk on Z -pad. Ill. Kick Tolerance A. With the planned mud weights, the kick tolerance for the intermediate section is 25 bbls with a 12.7 ppg leak -off, and the production section is infinite with a 9.9 ppa leak -off. If plaffI1JeZrt10TT T values are not achieved, do not drill ahead without risk assessment and proper authorization. All kick tolerances are calculated based on a 0.5 ppg kick intensity over likely pore pressure. IV. Integrity Testing Test Point Test Depth Test pe EMW (Ib! al) 9-%" Shoe 20' S0' from the 9-5/8" Shoe LOT 12.7 ppg minimum (25 bbls) 13.7 ppg target 50 bbls) T' shoe 20'-50' from the 7" shoe FIT 9.9 ppg minimum (infinite) 12.5 ppg target (infinite) V. Hydrogen Sulfide A. As Z -Pad is considered an H2S site, refer to the ADW "Hydrogen Sulfide" SOP for the appropriate operational guidelines. The max recorded H2S readings on the pad were 200 ppm in Z-67 March 2012. Z-65 (closest well at surface) recorded 10 ppm in February 2012. Z-69 PTD Page 11 6/5/2012 VI.

Anti -Collision Issues A. There are no anti -collision issues with existing wellbores. Z-61 directional plan #5 fails major risk with the planned Z-69 wellpath, however, Z-61 is early in the planning stages and the planned wellpath is likely to change. If anti -collision issues are not resolved, a tolerable collision risk spread sheet will be completed for both wells. CONSULT THE Z -PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION.
