Shut in well. Bled IA to zero 3/2: Fluid packed OA to try and determine where leak may be at. Started seeing more bubbles in conductor after pumping about 85 gallons of diesel in OA. Pumped total of 95 gallons in OA and pressured up to about 200psi. Did not hold pressure and pressure dropped after about 5-10 mins. Possible leak around 3-5 feet? 3/3: Pulled VR plug on back side of OA and connected N2 and pushed any reaming fluid out front side of OA. Then pulled back side off of OA and lowered string down to try and find fluid level. Was only able to lower about 10” to 12” due to muddy grease like substance. 3 /4 : Removed front OA valve and tried to lower string to check fluid level and was packed with mud. Hooked up diesel from back side to try and determine fluid level by calculating the volume of diesel to fluid pack OA. Took about 16 gallons and pressured up to 100psi and started seeing fluid bubbling from conductor. Total of 28 gallons pumped. Safed out well for well house and flowline removal. Maintenance started disconnecting electrical and instrumentation to prep for wellhouse removal and flowline removal. 3/5: Slickline showed up and rigged up and pulled SSSV and set plug and bled tubing to zero. 3/6: Pulled wellhouse, flowline and G/L line. Well is blinded at wing valve. 3/7: NES removed flooring and started snow removal behind well. Removable planks covering well cellar. 3/8: Pushed N2 from back of OA to front OA for about 10 mins and got nothing but N2 coming though OA. Took back side of OA off and dropped a bobbie into the hole to try and see the fluid level. Bobbie went down about 12” and hit fluid. Also pulled cap off cement return to verify there was no fluid in there and it was full of cement. 3/12: T/IA/OA= 0/0/0. BPV installed 3/13: Cellar floor cut out & removed 3/14: Excavated cellar to 88” below OA vlv & installed temporary shoring wall. 3/15: Excavated to total depth of 112” below OA vlv & lowered temporary shoring wall. Wind conditions did not allow for use of crane to move well support structure. 3/16: Crane to arrive today to move the well support structure. 3-17: Will be hooking up the electrical to the control shack & installing cross brace on WSS to the swivel on wellhead. 3-18: We cut circumferential cuts on conductor. As we were finishing up those cuts the cuts started closing up. Added more pull, up to 42,000 lb. Re-evaluate this morning and start on vertical cuts on conductor. Late start yesterday due to gen-set issues. We are now on shore power. 3-19: Removed conductor and left landing ring in place. All cement chipped off. Did not find the top of the leak. Saw bubbles coming up thru gravel. Determined we will have to excavate another 4 feet or so along with cutting of more conductor to get to the bottom of the leak 3-20: Excavated another three feet, total of 15.8 feet. Encountered a lot of water after 1.5 feet. Working water issues w/vac truck, shut down for night, cut casing and chip cement in AM. 3-21: Cleaned hole out from buffing and chipping, Mistras inspected, drew on grid, pipe looked good for 5 foot patch, working water issues. Plan forward: State inspection this am. Next step weld wedding bands. 3-22: AOGCC came by and did his inspection at 9am and then we vacuum out fluid from OA and then started welding wedding bands on. Should finish welding wedding bands this morning. 3-23: Finished welding wedding bands on and inspection done 24 hr timer started at 10:30am will start welding clam shell on after 24 hr wait is done and inspection is done. 3-24: Welded on External Clamshell 3/25/2021: Pre MIT done blue goo and rapped and started fitting up conductor 3/26/2021: Finished fitting up conductor and welded conductor. Plan forward: State MIT and then back fill hole. 3/27/22021: State MIT passed and filled hole with rock 3/28/2021: Filled conductor with cement left 6 to 12 in to add blue goo and removed cage and cross from well support. Put shipping bolts in to be ready for crane to lift off of well. MEMORANDUM TO: Jim Regg iz P.J.

I arrived on location and met with Larry McBride and John Allan (both Hilcorp). There was a giant surface gantry lift rigged up using the tubing head as the connection point. The well had been excavated and the conductor cut away exposing the surface casing. Inspection revealed extensive corrosion and two leaks 14 feet down from surface. Hilcorp's plan forward was to weld on a 4-1/2 ft long sleeve around the damaged area. The operation looked very good and all well -organized.

I. Supervisor State of Alaska Alaska Oil and Gas Conservation Commission DATE: FROM: Matt Herrera SUBJECT: Petroleum Inspector 3/2/2021 Wellhead Leak Duck Island Unit SDI 4-32 PTD 1950690 3/2/2021: On 3/2/2021 1 traveled to Hilcorp's Endicott Satellite Drilling Island to investigate a wellhead leak found by Operations during wellhouse checks. I met with Drillsite Operator John Houser and discussed what was found at Well 4-32 and their plan forward to address the issue. The cellar was dry and clean with no debris. The wellhead had what looked like calcium stains but no obvious leaks from piping or flanges. The casing head flutes had water in them and that was where the bubbling was coming from. Mr. Houser could not confirm if any LEL readings were taken. The bubbling was slight — maybe once every minute and a half; nothing to warrant or suggest an explosive or unsafe atmospheric condition. Operations suspects a surface casing leak and their plan forward is to have Slickline set a tubing plug and conduct MIT -T, MIT -IA and MIT -OA to try and determine which casing string is leaking and where communication is coming from. Well is currently shut in and is being monitored. Attachments: Photos (6) 2021-0302_Well_Integrity_DIU_4-32 mh.docx Page 1 of 4 Well Integrity — DIU 4-32 (PTD 1950690) Photos by AOGCC Inspector M.

Well names currently include a forward slash "/" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. 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 require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator . • BP Exploration (Alaska) Inc.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field 9-3607.
