Do not click links or open attachments unless you recognize the sender and know the content is safe. 2Injector R‐22A (PTD# 2141640)and R‐22AL1 (PTD#2141650) currently operate under AIO 4G.008 for slow TxIA and is restricted to PWI only. In 2017 an LDL was run in an attempt to determine the source of the IA repressurization while on MI service. Possible collar leaks were identified at 8290’ MD and 8308’ MD and a patch was installed over the two suspected leak points, but the IA repressurization continued with the well on MI and the well was restricted to PWI only as specified in AIO 4G.008, approved 2/15/2018. The well remained shut‐in from the approval of the original AA up to early 2020 when it was placed on PWI and began exhibiting slow IA repressurization. AIO 4G.008 was amended on 7/23/2020 to allow continued PWI with slow IA repressurization. Hilcorp request a temporary deviation from AIO 4G.008 to allow for the well to be placed Under Evaluation for up to 30 days on MI injection to monitor for IA repressurization and conduct a leak detection log to determine the location of TxIA communication such that we may attempt a repair and return the well to WAG service. An AOGCC witnessed MIT‐IA passed to 3284 psi on 04/14/2024 while on PWI. Maximum MI pressure at R‐pad in the last 12 months has been 3050 psi.

Before the patch was set,the well had a history of passing MIT5 on the IA even though it had anomalous re-pressurization.After the patch was set,the well was put on miscible gas injection on 01/26/18 and a state witness test was internally scheduled for 02/02/18.As to be expected,the fluid packed inner annulus showed a pressure increase as the well began to warm up, just recently it appears the pressures are stabilizing, however they are not completely stable. BP would like to extend the initial monitoring period for one week before scheduling the state witness MIT-IA so as not to introduce non thermally stable fluid into the IA and possibly confuse monitoring results of IA re-pressurization.

Report of Sundry Well Operations Summary June 15, 2017 To Whom it May Concern: Attached please find the Sundry Application for R-22A: This well was CTD as a Sag only injector in early 2015. Prior to drilling the laterals, the well had an IA cement squeeze to address TxIA communication. This appeared to be effective, however, when the well was POId in August 2016, communication issues again surfaced. A LTP was set in January of 2017 to seal the suspected leak path. The well was returned to injection, however, we have continued to see IA pressure build. The well was classified as UE on 3-11-17 and, after both operational and weather delays, an LDL was run on 5/18/2017. See attached Historical - Integrity tab for recent integrity notes. Due to the success of passing MITs to liquid, this patch will not be tested via MIT, rather, it will be returned to MI service and the IA monitored for pressure buildup. The LDL confirmed a leak in a collar at 8,308'. It also noted a possible collar leak at .1 8,290' which is unverified due to intensity of the signal from the deeper leak. Due to the lack of confirmation of the leaks at the higher location(s), a patch covering the entire . interval is desired. Sincerely, BP Exploration (Alaska) Inc. P.O.

First 15 minute/second 15 minute losses were 66 psi/27 psi. • 12/04/14: MIT-IA passed to 2500 psi on first attempt. First 15 minute/second 15 minute losses were 90 psi/29 psi. • 12/13/14: MIT-IA passed to 4000 psi on sixth attempt. First 15 minute/second 15 minute losses were 112 psi/46 psi. 1 • • The OA pressure did come up during yesterday's test.We increased the IA pressure 230 psi to begin the test, and the OA pressure came up 360 psi.The well has no history of IAxOA communication,and had a passing MIT-OA to 2000 psi on 05/26/2014. I plan to schedule wellhead diagnostics,to rule out slight IAxOA communication via the wellhead seals. In short, I believe we have ample evidence of two competent well barriers to the formation.With your permission, I'd like to leave the well online, reclassify as Under Evaluation, and reschedule another witnessed MIT-IA in the very near future, after we complete wellhead diagnostics,and at a time convenient for the Inspectors. Please let me know if this plan is acceptable.

The well was Not Operable prior to the sidetrack due to a packer leak. In December 2014,tubing by inner annulus communication was repaired with a cement squeeze. An MIT-IA passed to 4000 psi in December 2014 confirming two competent barriers in the wellbore. The well was classified as Not Operable due to the unavailability of MI on R Pad. With MI on the pad,the well is now ready to be put on injection and is reclassified as Operable. An AOGCC MIT-IA is required once the well is placed on injection and thermallystable.

The well was Not Operable prior to the sidetrack due to a packer leak. In December 2014,tubing by inner annulus communication was repaired with a cement squeeze. An MIT-IA passed to 4000 psi in December 2014 confirming two competent barriers in the wellbore. The well was classified as Not Operable due to the unavailability of MI on R Pad. With MI on the pad,the well is now ready to be put on injection and is reclassified as Operable. An AOGCC MIT-IA is required once the well is placed on injection and thermally stable.

Attachments: R-22A PTD 10-16-14.doc Steve, First, it looks like I mixed my numbers for reservoir pressure. The correct reservoir pressure is 3,432 psi (mixed up the 4 and the 3). However, my MASP number(2552psi) is still the same since I carried the correct number forward in my calculations. MASP Explanation:The RKB you refer to in your calculation is not the RKB of the Nordic Rigs in CTD. In CTD,we tie into the parent surveys. So the RKB we report is the RKB of the parent, not the rig. We decided as a group to use TVD at sea level to calculate MASP in order to simplify calculations and report the worst case scenario with gas to surface. Here is how I calculated MASP. 8800'TVD*7.5ppg*0.052= 3432 psi MASP=3432psi-(0.lpsi/ft)(8800')= 2552psi We will not pre-produce this well,just flow back to clean up slotted liner. Attached is the new PTD with the corrected reservoir pressure.Thank you for questions and please let me know if you any more questions.Thank you.

From: Davies, Stephen F(DOA) Sent: Wednesday, October 15, 2014 11:27 AM To: 'travis.boltz@bp.com' Subject: FW: R-22A/AL1 Directional Plan Joe,Travis: For PBU R-22,why does the ground level elevation on the Permit to Drill form (38.13')differ from the elevation in the directional survey plan (32.44')? Which is correct? Also,the reservoir pressure and MASP calculations seem to be a bit off(3342 psi at 8800'TVDSS is equivalent to 3342 psi at 8875'TVD; and 3342/8875=0.3766 psi/ft;so, 0.3766 psi/ft * 19.27 conversion factor=7.26 ppg equivalent. After subtracting the assumed 0.10 psi/ft gas gradient: 0.2766 psi/ft * 8875'TVD= 2455 psi MASP at rig-floor level). Or am I wrong? (Remember, I'm just a geologist.)
