Home My WebLink About197-081MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: Jim Regg �� 5�Z21 DATE: P. I. Supervisor FROM: Jeff Jones SUBJECT: Petroleum Inspector 2/18/2021 Surface Abandon PBU M -05A - Hilcorp North Slope LLC PTD 1970810; Sundry 319-329 2/3/2021: 1 traveled to Hilcorp's Prudhoe Bay Unit (PBU) well M -05A to witness the casing cut off and marker plate installation to permanently abandon this well. On arrival I met with Hilcorp representative Robert Bryan and we discussed the P&A procedures. All casing strings were cut off 4 feet below original tundra grade and cemented to the top. A 3/8" thick steel plate with the required well information on it was bead welded to the top of the outermost casing.

The cement was founded on fill with the proposed top of the plug at — 2667 ft MD (minimal inclination). A 2.5 - inch bailer slickline string (- 200 pounds) was used for the tag. The plug was tagged 251 ft higher than anticipated (3.8bbls) multiple times. A good cement sample was observed in the bailer once at surface. With the tubing previously punched from 2395-2400 ft MD this put the tubing, inner annulus and outer annulus in communication. A combination MIT -T, IA and OA was then attempted to a target of 2500 psi. Pressure was put down the tubing (notiumpered at surface) for the test, which all annuli tracked spot on during the pressurization and monitoring stages of the test. The initial test was ran to 75 minutes with minimal stabilization proven. The pressure was then "bumped" back up to 2750 two more times with similiar results. In all, two tests were ran to 75 minutes with the third to 30 minutes. Results of the test intervals shown above. In regards to the above casing removal data, the original tubing string could not be pulled in 2014. It was cut at— 9351 ft MD and pulled. A 4.5 -inch "kill string" was ran and engaged the previously cut tubing top with an overshot.

A PX plug was set at 11788' MD on 5/28/05 for a CMIT-T x IA x OA evaluation. When it came time to pull the plug, a tight spot was discovered at 9494' SLM and the plug was left at 11788' MD (this well has had scale problems in the past). In 2014, an RWO was attempted on the well. The RWO was a failure, while trying to pull tubing it became wedged and stuck inside the 9-5/8" casing around 9497' MD. The old tubing string was cut and pulled from a depth of - 9351' MD with a kill string with an overshot run to connect back to the old tubing. The RWO was abandoned at this point. Slickline drifted and attempted to get to the PX Plug at 11788' MD in June 2019. A full-size drift was unable to make it to depth. A smaller OD tool string was able to make it close to the plug depth but found fill on top of the plug. Last Pressure Test: CMIT TxIAxOA to 2500 psi PASSED on 5/21/14. Objective: Perform a full P&A on the well placing cement plugs in the wellbore. Excavate and cut casings 3' below original tundra level and install marker plate. This P&A was designed to conform to BP Practice 100221: Zonal Isolation and BP Alaska's deviation captured in eMOC 10439. DPZ 1: From 1858' MD - 6226' MD DPZ 3: Top at 12002' MD - Did not see the base Procedural Steps: Note recording requirements in RP: Through Tubinq Abandonments (section 5.9) that must be documented in A WGRS and the Wellfile. AOGCC Witness: All AOGCC witnessed operations require a minimum of 24 hour notice to AOGCC inspectors of the timing of the operation so they can be available. M-05 P&A Sundry 1) Fullbore A. Circulate the 9.8 ppg brine with surfactant pill, pumping down the tubing and up the IA.

B. If dye pill returns early, after pumping 574 bbls of 9.8 ppg brine, this will mean that there is communication at Unique Overshot (-9351'MD) and will need CT to complete the abandonment of the well. If dye returns on time, after pumping -664 bbls of 9.8 ppg brine, there is little or no communication from the Unique Overshot and Fullbore will be used to place the lower cement plug. • If dye pill returns early, then skip Step 2./Nii'fS • If dye pill returns at calculated volume, the ski teas 3 &/4W 4. C. Pressure test (Tbg x IA x OA) well to 2500 psi forXmins. This is to confirm there is still casing integrity.

What has Changed? The 4-1/2" completion was pulled to the parted GLM #5 at 6069'. A mechanical cut was made at 9,471' after a failed fishing run. The cut tubing was pulled. A drift of the 9-5/8" revealed partially collapsed Thermocase. Fishing resumed on the 4-1/2" tubing. After 15 hours of jarring the tubing had moved uphole 220' and no more progress made. A blind back off was made prior to pulling out of the hole. The recovered section of partially collapsed 4-1/2" tubing had mechanical damage from the 9-5/8" casing at -9497'. The tubing and casing damage are not able to be repaired. M-05A operations will be suspended Agreed Plan Forward The well is secure with a deep set plug. A kill string will be run to the top of the fish. The well will be loaded with inhibited seawater and diesel freeze protect. The rig will install a dry hole tree and set a TWC prior to moving off the well. Operation Steps: 1. Pull the wear bushing. 2. Prepare to PU kill string tubing. ➢ Driller will personally count total number of joints in pipe shed before running completion. ➢ Run 4-W 12.6# L-80 with 7"x 4-W Overshot. ➢ See the attached 'Proposed Suspend Operations Schematic'. ➢ Use Best of Life 2000 thread compound.

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.

It was drilled in 1976 and put on production in 1985. Since 1991, the well has been shut in for high WC and TGOR. The replace- ment well M-05A is planned as a high angle multilateral sidetrack targeting Ivishak and Sag River reserves. A long high angle section of 2000' is planned for the Ivishak with 1500' planned for the Sag R. Long sections will maximize production and reserves for the predicted Iow productivity, thin NLOC and large area of the reservoirs. M-05A is expected to drain 210 acres with OIP of 9 MMSTB for both Ivishak and Sag R.
