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 6/1/2023. 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.

It is currently a shut in producer due to a surface casing leak. The 9-5/8"x13-3/8" intermediate casing was set at 9466' MD. A 3 stage cement job was performed. The first stage pumped 368 bbls of 12.8 ppg class G cement through the 9-5/8" shoe. The plug was bumped, and no losses were seen. Based on 30% excess, TOC is estimated to be at -4490' MD. The 2nd stage was performed after opening the 9-5/8" stage collar at 5025' MD, and no cement returns were seen when circulating through. Assume TOC of 1st stage is at stage collar or 5025' MD. 354 bbls of 12.8 ppg class G cement, was pumped during the second stage. Based on 30% excess, TOC is estimated to be at -1383' MD. The plug was bumped, and no losses were seen. The 3rd stage was performed after opening the 13-3/8" stage collar at 2246' MD, and no cement returns were seen when circulating through. Assume TOC of 2nd stage is at stage collar or 2246' MD. 331 bbls of 13.5-14.0 ppg Permafrost II cement was pumped during the third stage. Cement returns were seen at surface. - N-18A - N-18A was drilled and completed in December of 2008. It is currently an online producer. The 7" intermediate casing was set at 9744' MD. The cement job pumped 163 bbls of 11.0 ppg lead slurry, followed by 19 bbls of 15.8 ppg class G tail slurry. Full returns were seen throughout the job and plug was bumped. A USIT performed after the job showed TOC estimated to be at 3210' MD. R-14B - R-14B is currently an online producer. It was originally planned to be a rotary sidetrack. When running 7" intermediate liner, the liner became stuck, and all attempts to work it to bottom failed. The 7" liner was set at 10075' MD, which was -2920' off bottom, and cemented in place. The 7" liner was cemented with 53 bbls of 15.8 ppg class G cement. The plug was bumped on schedule and no losses were seen. TOC was N-29i PTD Page 3 7/15/2014 • • estimated at 7728' MD based off of matching observed and modeled lift pressures. The 7" shoe was drilled out and the below 8-1/2" hole was attempted to be cleaned up, but all attempts were unsuccessful. A 7" EZSV bridge plug was set and pressure tested, and a 7" whipstock was set above. A 6-1/8" hole was then sidetracked at 9932' MD and drilled into the top of the Sag River to a TD of 12977'. A 4-1/2" liner was set at TD and cemented. The 4-1/2" liner was cemented in place by pumping 22 bbls of 11.0 ppg litecrete lead slurry, followed by 13 bbls of 15.8 ppg class G tail cement. Modeled lift pressures for 1500' MD of cement matched the lift pressures observed. TOC estimated to be 1500' above shoe (-11477' MD) based on matching modeled and observed lift pressures. R-12 - R-12 was drilled and completed in March of 1985. The 9-5/8" intermediate casing was set at 10287' MD. The first stage pumped a lead slurry of 246 bbls of 13.2 ppg class G cement, followed by a tail slurry of 102 bbls of 15.8 ppg class G cement. Although the plug was not bumped, no losses were reported. Based on volume pumped, this puts TOC between 5488' MD and 4048' MD from 30% washout to gauge hole. R-12A - R-12A was a rotary sidetrack that was drilled and completed in September of 2011. It is currently an online producer. The 7" intermediate casing was set at 10444' MD. 86 bbls of 15.8 ppg class G cement was pumped.

While the flow paddle is removed from the flow line, PVT alarms will be used and the pit levels accurately monitored for any pit gain. Also, a visual check will be made during connections by looking down the riser to ensure the well is not flowing. After returned debris that could plug the flow line diminishes the flow paddle will be reinstalled.

Prior to picking up or running any equipment or tools in the hole, a PJSM and discussion is required to identify and note any equipment which will be run through the BOPE and is non- shearable. A risk assessment shall be performed for any equipment which is deemed non-shearable. The risk assessment must address the following: 1. Can variable bore rams seal against the equipment? 2. Can an annular preventer seal against the equipment? 3. Is a cross-over readily available to make-up into equipment? 4. Is a single joint or full stand of DP readily available to lower equipment below the BOPE stack? 5. How the equipment can be intentionally dropped down hole. 6. Are weights of equipment known so that hydraulic jacking force of wellbore pressure can be calculated. 7. Accurate and up to date shearing capabilities for the current shear rams installed is available. 8. Has each crew member been versed on individual roles and responsibilities? If there is a well control event happens with non-shearable equipment across the BOPE shear rams, the following procedure should be followed: 1. Based on the risk assessment above, gain control of the well by either: a. Closing the appropriate preventer(pipe ram, VBR, or annular) or b. Placing a sealable piece of equipment across the BOPE and closing the appropriate preventer or c. Dropping equipment and closing the Blind or Blind/Shear rams. 2. If well conditions permit, contact appropriate personnel. If not,proceed with well kill operations. This may include placing shearable equipment(i.e. drillpipe) across the shear rams by stripping in/out of the hole.

N-29i PTD Page 14 7/15/2014 • N-29i Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. Surface Hole—the interval is normally pressured. No shallow gas is expected in the interval, and there y` are no reported incidents of offsets running into overpressured zones or shallow gas. Planned mud weight will range from 8.6-9.0 ppg. B. Intermediate Hole -the planned mud weight will be ranging from 8.8— 10.3 ppg depending on depth of drilling. Sufficient mud weight will account for: 1. Potential cretaceous injection pressures (9.3 ppg max). • 2. Predicted Colville pressures (9.65 ppg max). . 2. Sag River pore pressure (7.1 ppg max). ' 3. HRZ and Kingak shale stability (10.1-10.3 ppg). ✓ C. Production Hole - The Sag River and Ivishak formations in this area are expected to be under- . pressured at 7.1 ppg EMW. This interval will be drilled with a 8.6 ppg reservoir drill-in fluid. II. Lost Circulation/Breathing A. Surface Hole- Lost circulation is considered a minimal risk if mud properties remain in specification. B. Intermediate Hole - While no major lost circulation is expected in this interval of the well, breathing and/or lost circulation is a possibility due to exposing formations from the 9-5/8" casing shoe to the TSGR to drilling ECD's associated with the planned 10.1-10.3 ppg mud density. If the fault in the Kingak is crossed, the lost circulation risk is considered to be medium, however the current directional plan has a projected standoff of—100' from the fault. C. Production Hole - There is a history of lost circulation in the production hole at N-pad. Most of these events are associated with crossing faults. There are no planned fault crossings in the production hole, but if lost circulation is encountered, follow the mud program's lost circulation decision tree. Ill. Kick Tolerance/Integrity Testing A. With the planned mud weights, the frac gradient required for a 25 bbl kick tolerance in the intermediate section is 12.21 ppg, 13.40 ppg for a 50 bbl kick tolerance, and 8.82 ppg for an infinite kick tolerance in the production section.

Faults There are no planned fault crossings with the current directional plan. However, there is a nearby fault crossing that will be passed over in the Kingak shale that may cause casing point pick uncertainty in the top of the Sag River. VI. Anti-Collision Issues There are no anti-collision issues associated with the directional plan, that require shut in and/or minor risking rules to be applied. However, always be sure to adhere to the travelling cylinder plot when drilling ahead. CONSULT THE N-PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION.
