Post Office Box 244027 Anchorage, AK 99524-4027 3800 Centerpoint Drive Suite 1400 Anchorage, AK 99503 Phone: (907) 564-4891 01/12/2023 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 4Q 2022. 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 the end of 4Q 2022. 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.

The grassroots well is a horizontal producer targeting the Ivishak Zone 4 South of W-pad. The planned well has four hole sections utilizing the Big Bore hole design. Surface casing will be set shallow in the SV3 to avoid drilling potential free gas - while on diverter. The first intermediate hole section will set a fully cemented liner in the UG3. The second Intermediate hole is planned as a casing string which top sets the Sag River formation. The production interval will be completed with a cementless liner using sliding sleeves and swellpackers. The liner is designed to allow selective production along the horizontal lateral to maximize oil recovery and minimize intervention requirements. The maximum anticipated surface pressure from the Ivishak/Sag with a full column of gas from TD to • surface is —2682 psi (assumes 7.93 ppg as max pore pressure). This well will be drilled by Parker 273 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 Parker 273 and function test diverter. 2. Drill 16" surface hole to—2808 ft MD. • 3. Run 13-3/8" surface casing and cement to surface. 4. Nipple up BOPE and test. 5. Pressure test surface casing. Drill out shoe and perform LOT. 6. Drill 12-1/4" Intermediate hole#1 to—4003 ft MD. 7. Run 9-5/8" liner and fully cement. 8. Positive and negative pressure test Intermediate#1 liner. Drill out the shoe and perform LOT. 9. Drill 8-3/4" intermediate hole to top of the Sag River at—9,383 ft MD. • 10. Run 7" casing and cement to —650 ft TVD above the Na sand. Pressure test casing. 11. Drill out of intermediate shoe and perform FIT. 12. Drill 6-1/8" horizontal production hole through Zone 4 of the Ivishak to TD at—11,640 ft MD. • 13. Run a 4-1/2", chrome, production liner with approximately 9 swell packers and 8 sliding sleeves. 14. Pressure test liner top packer to 3500 psi 15. Run 4-1/2" chrome completion tubing. Sting into liner tieback sleeve and set production packer. 16. Pressure test the tubing and the inner annulus to 3500 psi each. 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.

Haul Class I waste to DS-04 and/or Pad 3 for disposal/Contact the GPB Environmental Advisors (659-5893) for guidance. Well Control The 16" surface hole will be drilled with a diverter. The 12-1/4", 8-3/4" and the 6-1/8" hole sections will be drilled with well control equipment consisting of 5,000 psi working pressure pipe 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 3500 psi. BOP test frequency for W-51 will be 14 days with function test every 7 days. Except in the event of a significant operational issue that may effect well integrity or pose safety concerns, an extension to the 14 day BOP test period should not be requested. lj Intermediate Interval #1 / Maximum anticipated BHP 1475 psi at 2955' TVDss (9.6 ppg EMW) Maximum surface pressure 1180 psi (.10 psi/ft gas gradient to surface)from 2955' TVDss (9.6 ppg • EMW) 25 bbls with 11.7 ppg frac gradient Kick tolerance Assumes a 0.5 ppg kick intensity over the anticipated 9.6 ppg pore pressure at interval TSV1 with a 9.8 ppg MW(worst case kick zone for interval).

After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line (<1000 ft). 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. • Over 50 surface holes have been drilled on W-pad, 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.

Surface Hole: No overpressure is expected in the surface hole and hydrates have been a minimal concern on the pad. The Surface casing shoe is planned at a shallow depth in the SV3 to avoid drilling potential free gas in the SV1 while on diverter. Mitigating free gas while on diverter with a shallow surface casing shoe requires a 9-5/8" Intermediate liner to avoid sustained casing pressure in the Outer Annulus during the life of the well. B. Intermediate #1 Hole: There is potential for the SV1 to be over pressured as high as 9.6 ppg. A minimum mud weight of 9.8 ppg will be utilized to provide adequate over balance to potential free gas. The short interval, with minimal TVD change, provides substantial kick tolerance. The Big Bore hole design allows the free gas to be drilled with BOPE installed. C. Intermediate #2 Hole: Pore pressure is anticipated to be over pressured beginning in the CM1 at 6010 TVDss. Drilling fluid density will increase to 10.2 ppg prior to drilling into the CM1 and remain over balanced to predicted pore pressure throughout the interval. A minimum kick tolerance of 25 bbls should be achieved prior to drilling interval. D. Production Hole: The pore pressure in the production interval is anticipated to be under pressured due to offset well production with limited injection support. The highest anticipated pore pressure is 7.90 ppg. Expected FIT provides an infinite kick tolerance. The interval will be drilled with a substantial over balance utilizing an 8.5 ppg fluid. II. Lost Circulation/Breathing A. Surface Hole: Lost circulation is considered a low concern, but running gravels and large washouts are known issues on W-Pad. Mud properties must remain in specification to reduce risk wellbore stability issues. W-34 (closest well at surface) was drilled in 1988 increasing the risk of a thaw bulb nearby. B. Intermediate #1 Hole: Lost circulation is considered a minimal risk with no fault crossings and reasonable overbalance. Maintain mud properties and hole cleaning to further prevent lost circulation. C. Intermediate #2 Hole: Breathing and/or lost circulation is a possibility due to 1 fault crossing in the CM2 with —110 ft of throw. Breathing is also common in the Colville. Two other faults in the Kingak with throws of —80 ft and —15' respectively pose a lost circulation risk. Wellbore stability requires a 10.6 — 10.8 ppg drilling fluid, further increasing the risk of lost circulation and breathing. ECD management is critical and fluid properties must remain within specification. If lost circulation becomes a problem, follow the LCM decision tree provided in the drilling program. Utilize good hole cleaning practices to avoid high ECD and prevent pack-off potential which could induce breathing. D. Production Hole: There are no planned fault crossings in the production hole. Remain inside the drillers polygon to avoid drilling too close to bounding faults surrounding the target area. Additionally, be prepared for breathing in the Shublik if fractures exist in the area. This has been an occasional problem across Prudhoe and is considered a moderate risk on W-pad. III. Kick Tolerance/Integrity Testing A. With the planned mud weight, the kick tolerance is 25 bbls with a 11.7 ppg LOT in the first intermediate section and 11.9 ppg LOT in the second intermediate section. The production interval kick tolerance is infinite with a 9.4 ppg FIT. If planned LOT/FIT 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 type EMW(lb/gal) 13-3/8"Shoe 20'-50'from the 13-3/8" Shoe LOT 11.7 ppg minimum(25 bbls) 12.0 ppg target(50 bbls) 9-%"Shoe 20'-50'from the 9-5/8"Shoe LOT 11.9 ppg minimum(25 bbls) 12.4 ppg target(50 bbls) 7"shoe 20'-50'from the 7"shoe FIT 9.4 ppg minimum(infinite) 12.5 ppg target(infinite) W-51 PTD Page 11 3/26/2013 V. Hydrogen Sulfide A. As W-Pad is not 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 60 ppm in W- 15A January 2011. W-34A recorded 20 ppm 2/10/2012 (closest well at surface). VI.

Parker 273 Close Approach Analysis We have examined the potential intersections of the subject well with all other potentially conflicting wells, according to the BPA Directional Survey handbook (BPA-D-004) dated 09/99. Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two hundred feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. 3. All depths are relative to the planned well profile.
