Its parent well, W-40, was also drilled as a pre-produced WAG injector. Jut prior to the sidetrack, a SC leak was successfully repaired with a welded casing patch on 10/1/22 and passed a subsequent OA integrity test on 10/3/22. W-40A CTD drilling began on 10/17/2022 and was completed on 10/26/2022. 510’ of perforations were shot with the rig, but due to a firing head malfunction they were shot 1,260’ off depth. After CTD rig moved off, coil tubing returned to shoot new perforations in the correct intervals and squeezed the previously shot, off-depth perforations. The well was put on production, but recently became uncompetitive due to high water cut and high gas lift requirements. The well is now planned to be converted to a water injector to provide support to W-39A and W-45. Notes Regarding Wellbore Condition: x The well last had a passing warm and cold TIFLs on October 2018. x 8/10/2009 RG-2041 “Blue Goo” treatment volume on conductor was 1.7 gallons/2” below conductor landing. x OA previously leaked off at ~.25BPM during MIT-OA to 2000 psi in 2005 but with no observable bubbling at surface. x Surface casing leak ~79” below the OA valve repaired on 10/1/22 x 10/28/22 CTD drilled a sidetracked and perforated ~1,260’ off target depth. x Liner lap test failed on 10/28/2022 .55 BPM @1,115psi x 11/26/22 CTU added perfs at target interval and squeezed perfs shot off depth Objective: Convert W-40A from Ivishak producer to Ivishak water injector, add perforations to provide optimal support to W-39A and W-45. Target Exemption: Hilcorp requests an exemption for 20 AAC 25.412.(b) which requires “…The packer must be placed within 200 feet measured depth above the top of the perforations, unless the commission approves a different placement depth as the commission considers appropriate given the thickness and depth of the confining zone.” The current top open perforation is at 11,740’ MD (8941’ TVD) with the current production packer at 9511 MD (8352’ TVD) making the packer 2229’ MD (464’ TVD) above the top perforation. -00 DLB Conversion to Injector WELL:W-40A PTD:222-103 Target well Cement Evaluation: W-40 (parent well to W-40A) was a pre-produced WAG injector drilled in 1988. The 12-1/4” hole was drilled without major issues. The 9-5/8” casing was run from surface to 9931’MD and cemented with 2119 cu. Ft of class G cement. Cement and casing tested good to 3000psi. After four years of being online as a producer, W-40 was converted to a gas injector. It was a gas cap injector in the Ivishak from 1991-2001, and then became a gas cap water injector until 2007. In 2007, a RWO repaired TxIA communication and brought the well back online as a producer. There were no evident issues with confinement within the Ivishak while on injection. Area of Review – PBU W-40A (PTD # 2220103) Prior to the conversion of well W-40A from Ivishak producer to Ivishak injector, an Area of Review (AOR) has been conducted. This AOR found four wells and former wells within ¼ mile of W-40A’s lateral in the reservoir. TOCs were interpreted from logs or estimated using the daily drilling logs found in the original well files. See attached table Area of Review W-40A for TOCs and zonal isolation of all wells within the AOR.

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.
