I have the opportunity to grab the ASR rig on 11/24. I would like to complete the RWO with that unit. No change to the sundried program, just the rig and supporting BOP stack.

As stated by Hilcorp: work will continue with Eline work to diagnose a casing leak. A new sundry should be created to begin the Eline work and re-MIRU Thunderbird rig to complete tubing swap.

We are isolated to reservoir with a XX plug at 9,534’ The well bore has shown no signs of hydrocarbons after we were able to circulate on bottom. We will set a scoop guide on the tubing stub with slickline and run a 2,000ft 3-1/2” kill string for freeze protect and well monitoring. We will use e-line to diagnose the casing leak and return with a plan to repair in the next 3-4 weeks pending equipment availability. Please let me know if you have any questions.

We attempted to test to 3,000-psi and found a leak 0.25BPM at 2,730 psi. We were unable to do additional WL diagnostics like a LDL due to the parted tubing. I will add an additional step in the RWO program to get a casing pressure test on the rig using a service packer on the workstring. We will add the additional BOP test to accommodate the 2-7/8” workstring also. Let me know if you have any questions.

Diagnostic work summarized below did not indicate any OA integrity issues. The pressure spike observed on 10/12/17 is believed to have been caused by thermal fluid expansion that went undetected due to an issue with the annulus gauge. At this time the well is reclassified as Operable. Work Completed: 1. Wellhead: Positive Pressure Packoff Test—Passed to 3,500psi on 10/17/17 2. Fullbore: MIT-OA-Passed to 1,200psi on 10/18/17 3.

I. Supervisor DATE: May 7, 2001 FROM: Chuck Scheve; SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Drill Site 12 Monday, May 7, 2001: i traveled to BPXs Drill Site 12 and witnessed the semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 21 wells and 42 components with 1 failure. The surface safety valve on well 12-12 had a slow leak when pressure tested. This valve was serviced and retested by the operator on this date. Bill Preston (lead DS operator) performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment aPpeared to be in good condition. Summary: I witnessed the semi annual SVS testing at BPXs Drill Site 12.

The permit to re-drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting re-drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 ,&AC 25.035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling a new hole.

Diverter, BOPE and mud fluid system schematics on file with AOGCC. Hazards and Contingencies Mud weights should be kept to a minimum while drilling through the horizontal section (+9.0 ppg) to prevent differential sticking. With 9.0 ppg the hydrostatic is +4195 psi which is well over the formation pressure of +3430 psi.

MARY PROCEDURE Pre-Rig Work: NONE well has been temp. aband with retainer and cement squeezed below, cement, plugs and casing has been pressure tested while witnessed. Move in drilling rig. Check well for pressure and flow, rig down dry hole tree and rig up BOPs. Install BOPs and test to 5000 psi. Remove the TWC valve. Circulate diesel freeze protection cap from well and recover for future use. Run in with a 6 3/4" steerable drilling assembly and a 8 1/2" bit with gamma ray/directional MWD. Dress the cement to 5' below the section top. Kickoff displace well to used FLO-PRO system. Continue to directionally drill to the 7" casing point at _+10241' at 83.8° (see attached directional plan). Make a conditioning trip with an 8 1/2" hole-opener for the open hole section Install a used 7", 29#, L-80, BUTT Solid liner with 7" X 9-5/8" packer/hanger. Packer / hanger to be set at _+8646' MD. Cement the liner in place with the total cement volume based upon 50 % open-hole enlargement plus the 80' shoe volume, 9-5/8 X 7" lap volume, and 150' excess on top of the liner with drillpipe in the hole. Re-test BOPs as needed. PU 3 1/2" drill pipe and 4 3/4" steerable drilling assembly with gama ray and directional MWD. RIH and cleanout liner to landing collar, test casing to 3500 psi. Drill out shoe and continue to drill horizontally to 11352' MDTD. Install a 4 1/2",12.6#,L-80,BUTT slotted liner with 4 1/2" X 7" hanger/packer. .The liner hanger is to be at _+10091 '. There exists a possibilty that the liner will be run with two ECP,s as dictated by geology. Run the used 3-1/2" L-80 completion string assembly using as much 3-1/2" used tubing and jewelry as possible. Space out and circulate with corrosion inhibitor. Install a BPV and test plug. Remove BOP's. Install and test the production tree to 5000 psi. Pull tree test plug and BPV. Set packer. Test the tubing x casing annulus to 3500 psi for 30 minutes. Shear RP valve in the upper GLM and freeze protect the well. Set a BPV. Release rig. Complete appropriate documentation and hand-over to Production.
