Anticipated Surface Pressure:2,334 psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP: 2320 psi (Taken on 12/8/2023) Min ID:2.45” – Baker patch @ 11,030’ MD Brief Well Summary: J-13A is a rotary sidetrack drilled in 2010. Bubbling and LELs were detected inside the conductor flutes on 7/19/24. Subsequent diagnostics verified a surface casing (SC) leak via nitrogen pumped in the OA to 350 psi with a commensurate increase in bubbling in the conductor flutes. The 13-3/8” x 9-5/8” annulus (OA) was cemented from 1,754’ MD to surface during the 2010 sidetrack de- complete via a 9-5/8” cut n’ pull tieback. The TOC in the OA was strapped @ 31” on 7/31/24. Objective: Execute an OA downsqueeze with cement and/or Well Lock. POP the well Under-Evaluation and monitor the cellar/conductor flutes to validate that the SC leak is fixed. Well Integrity: o PPPOT-IC passed 7/20/24 o TIFL passed 7/4/24 Procedure: DHD 1. Bleed IA pressure down to close to 0 psi. 2. Top off the OA with cement and/or Well Lock. 3. Squeeze the OA to 1200 psi with Microfine cement and/or Well Lock to seal off the SC leak. 4. Top off conductor cement with a cement top job (TOC in conductor last tagged @ 4’3” in 2009). Operations/DHD 5. POP Under-Evaluation & monitor cellar/conductor flutes every tour for bubbling. 6. If bubbling persists re-squeeze the OA with cement or Well Lock. 7. If bubbling and LEL readings do not re-appear for two weeks while online then revert the well status to Operable. Attachments: 1. Wellbore Schematic 2.

Jacob, The delay in LPRs' testing is approved ... you have it actually inserted after Step 7, I believe you want it right after step 5 ( pulling the 7" tubing) . Regarding the request to forego C/O to 9 5/8" BOP rams... your argument to not swap rams has merit. With a shallow 13 3/8" surface casing leak the rams become essentially diverters. You will have two tested barriers down -hole to isolate from the reservoir already. 1) Cement plug over perfs that is pressure tested... 2) 9 5/8" EZSV at 9640' and which will be tested to 3500 psi I will replace the page 8 and 9 (Operations Summary) of the wellplan with the version attached. Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793 -1226 (office) 444 -3433 (cell) From: Thompson, Jacob [mailto:Jacob.Thompson ©BP.com] Sent: Thursday, June 03, 2010 7:44 AM To: Schwartz, Guy L (DOA) Cc: Egbejimba, Uchenna J Subject: 3-13A Change in Verbiage Guy, Could you please approve of the change in verbiage to step 5 of the operational summary for J -13A. (requesting delayed testing of the LPRs) Also we do not plan on changing out to 9 -5/8" rams prior to pulling our 9 -5/8" CSG, so step 11 will not be done. This step is eliminated because there is a surface CSG teak in the 13 -3/8" 4' -3" from surface. There are two tested barriers in the well at this time and the rams don't buy us any assurance because a well control incident would leak out of the surface CSG. Please give me a call if you have any question. «J -13A Draft Permit to drill Revision.doc» Jacob Thompson 6/3/2010 J -13A Change in Verbiage • Page 2 of 2 GPB Rotary Drilling Cell: (907) 854 -4377 Office: (907) 564 -5579 6/3/2010 • • CIF ALASKA SEAN PARNELL, GOVERNOR t� ALASKA OIL AND GAS 333 W. 7th AVENUE, SUITE 100 CONSERVAi`ION COMMISSION ANCHORAGE, ALASKA 99501 -3539 PHONE (907) 279 -1433 FAX (907) 276 -7542 Greg Hobbs Engineering Team Leader BP Exploration (Alaska), Inc.

During drilling operations the exit will be from the 9 -5/8" casing at approximately 9596' with an 8.5" milling assembly. The 8.5" hole will be drilled from to the top of the Sag River where a 7" liner will be run to 150' inside the 9 -5/8" casing. The 7" liner will be fully cemented. The production hole will be drilled with a 6" BHA, which will run through the Ivishak formation. The production liner will be 4 -1/2" 13Cr -80 and be fully cemented. Tubing will be 4 -1/2" 13Cr -80, and tied into the top of the production liner.

Well Control Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind /shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3,500 psi. BOP regular test frequency for J -13A will be 14 days during drilling phase and 7 days / during decompletion and surface casing work.

The Ivishak in this fault block is expected to be 7.0 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for producing wells. II. Lost Circulation A. J Pad is in the med risk zone for LC according to the WURD lost circulation study. There are no expected fault crossings in the planned wellpath; however there are several faults in the nearby area. B. According to the pad data sheet several wells have experienced losses in the Ivisaak z2 sometimes leading to stuck pipe and lost BHA's. III. Kick Tolerance /Integrity Testing A. With the a 10.5 ppg mud weight and a 11.0 ppg LOT /FIT an infinite kick tolerance was calculated for the intermediate hole section. The production interval's kick tolerance was calculated to be infinite using a 8.5 ppg mud weight and a 9.0 ppg FIT /LOT. B.

Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drillin BOP configuration is preferred to a two ram configuration with a spool, BPXA will execute the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE as follows when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams: That lowest set of rams will be tested at the earliest opportunity during path - forward de- completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three -ram drilling BOP stack. 8.
