Please see corrected surveys for PBU 04-29A, 04-29AL1 and 04-29AL1PB1, if you have any questions please don’t hesitate to let me know. Thanks!

The OA was fully cemented during a RWO in 2010. The OA does not repressurize when the well is online, but does when the well is shut-in. CMIT-TxIA passed to 1970 psi on 12/13/2012. A cold TIFL passed on 7/12/2021. Current Status: 04-29 is currently under evaluation starting 07/27/2021. Scope of Work: Squeeze OA with Well Lock (or similar) to mitigate intermittent OA re-pressurization.

I in turn called Guy Schwartz, Senior Petroleum Engineer AOGCC and discussed the situation. He advised us to leave a message with the Slope AOGCC stating that we will be starting the ROPE test at 17:00 without witness unless otherwise directed by an inspector. Doyon 141 will start their BOPE test around 17:00 unless otherwise directed by the AOGCC or BPXA management. Please feel free to contact myself or Mr. Burson (659 4784) with questions or comments.

That work has not been completed yet. The IA leak rate was too small to measure @ 3000psi last time it was checked. Tubing held to 3000 psi last time we checked. Both those tests were done in 2007 and need to be redone. A leak detect log showed a leak @ 9974' which is suspiciously close to liner top packer depth. Step 5 in the main procedure is testing a 9.625" bridge plug @ probably 2500'. If the pre-rig IA test fails we'll move the packer test up from step 11 in rig portion of the program and find our leak(s). Terrie left copies of the 2 sundries she filed for this well on my desk, so you should already have the dual paperwork. Hope that answers your questions. Dave Bjork will be taking this well so let him know if it doesn't. Thanks, Hank Baca Drilling Engineer 907-564-5444 of1'ICe 907-748-0997 cell From: Schwartz, Guy L (DOA) [mailto:guy.schwartz@alaska.gov] Sent: Monday, April 12, 2010 1:54 PM To: Baca, Hank Subject: 04-29AL1 RWO (PTD 200-178) Hank, In reviewing the RWO I did't see the current CMIT results listed. You state a IA X OA leak but don't indicate the rate loss or where it is located in the 9 5/8" casing. Will it hold 1000 psi ??? (ie step #5) Is the OA arctic packed?? Was curious as to what evidence there was for the liner lap leak too. Could you elaborate on this.... In addition the Sundry is written under the L1 lateral PTD. The motherbore PTD 04-29A) would be more appropriate but in reality the wellwork should be reported for both PTD numbers. Please submit another sundry for 04-29A . At completion wellwork reports (404's) will be needed for both motherbore and 04-29AL1. I realize this is some duplication but it keeps our well records complete. Don't hesitate to call if you have any questions. Thanks in advance. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) 4/12/2010 ON OR BEFORE c:LOP.

The test went very well. A Iow/high test of 250~5000 psi was put on all BOPE with the exception of the annular preventer which was tested to 250/3000 psi. A recharge test was performed that showed the accumulator was in satisfactory shape. The choke manifold was tested with all valves operating properly and holding their pressure test of 300/5000 psi. The Gas detectors showed a fault in the calibration, as the dg would not be ready to ddll out until the next morning I allowed for them to wait until the electrician came on in the morning to check them out. I instructed Robert French the detectors were to be checked and calibrated before drilling out the cement plug that had been laid in the casing. I found the condition of the dg to be in very good shape. Wednesday, December 13: I checked on the gas detectors today and found them to be calibrated and operational. Robert French informed me that the backup battery had gone bad and needed to be replaced. SUMMARY: I witnessed the weekly BOP test on Nabors dg # 2 ES ddlling Arco well # DS 4-29A. Test time 3 1/2 hours, two failures, the gas detectors.

Pull 12 stands, shut in and perform hesitation squeeze. Attempt to achieve a 1000-2000 psi squeeze but do not displace TOC below 100' above section top. . Run in with an .8-1/2" steerable assembly (MWD - directional) and dress the cement to 5' below the section top. Circulate hole clean. Kickoff and directionally drill to the target at 12563' MD ( 8828' TVDss ). See attached directional plan #3. ( Use sample catchers - 100' from the target and while drilling 6" horizontal hole ) 10. After DP conveyed logs are ran ( logging program is triple combo, where density Icg may be run in place of acoustic Icg. This will be determined by geology ) make a conditioning trip with a 8 1/2" hole-opener for the open hole section with a 9 5/8" casing scraper spaced to clean the casing.

( Packer will be set to allow for the tail pipe above the future potential zone of interest for CTU drill out ). Refer to Standard Recommended practices for liner running procedure. Reciprocate liner 20-30' during circulation and cementation. 13. Cement the liner in place with the total cement volume based upon 30% open-hole enlargement plus the 80' shoe volume, (TOC 1000 ft MD above the TSAD which in this case means about 250 sks but this number must be reconfirmed after the hole is drilled ). Set liner hanger / packer with 4200 psi. Reverse out clean. 14. Re-test BOP's as needed. (just a friendly reminder ) 15. Run in with 6'~ steerable drilling assembly (MWD - GR) on 4-1/2" x 3-1/2" drillpipe. Clean out to landing collar. Test casing to 3500 psi for 15 min. Drill out of shoe joints plus 10' new hole. Displace hole to FLO-PRO system 16. 17. Drill approximately 1000' of 6" hole horizontally to TD of @ 13563' MD. See attached directional plan. ( Utilize sample catchers ) 4- · The most likely scenario from here will be to run solid 4.5" liner. There is a very slight chance that we may run slotted liner and if that happens we will revise this procedure accordingly. 18. 19.

Reciprocate liner 20-30' during circulation and cementation. Cement the liner in place with the total cement volume of 170 sks ( based upon 30% open-hole enlargement ) plus the 80' shoe volume, 150' lap volume and 150' excess on top of the liner with drillpipe in the hole.
