A SBHPS performed in April of 2024 indicated a very low BHP (2192 psi @ 8800’ TVD). Objective: Convert the well to a WAG Sag injector to support surrounding Sag producers. Integrity Screening: o MIT-IA passed to 3,242 psi on 4/28/24 o MIT-T passed to 3,349 psi on 5/14/24 w /plug set in X-nipple @ 7,721’ MD (in Sliding Sleeve) o MIT-T passed to 3,104 psi on 7/5/24 w/ plug set in X-nipple @ 7,833’ MD (in CT Liner top below production packer) o Gas-tight tubing test w/ 2800 psi MI 5/23/24 – 5/29/24 passed w/ plug set in X-nipple @7,721’ MD (in Sliding Sleeve) o Gas-tight tubing test w/ 3000 psi MI 6/22/24 – 6/24/24 w/ plug set in X-nipple @ 7,833’ MD (in CT Liner top below production packer); IAP increased 500 psi in two days Cement Isolation Original completion: o 7” liner cemented w/ 400 sacks Class G w/ 5% KCL o RIH w/ 8-1/2” bit and clean out cement from 8406’ to top of 7” liner @ 8817’ MD (this indicates cement returns achieved over the to of the 7” liner) o RIH w/ 6” bit and clean out top of 7” liner. Clean out cement from 9477’ to 9557’ MD CTD completion: o Cemented 3-3/16” Liner w/ 35 bbls cement w/ full returns throughout the job o Performed CBL on 3-3/16” Liner on 7/5/24: Good cement bond from ~8640’ MD to bottom of logged interval ~9300’ MD. Base of Kingak is ~9180’ MD. Therefore we believe we have zonal isolation in the 3-3/16” x 7” annulus and the 7” x OH annulus also has evidence of cement across the Kingak since cement was cleaned out off the top of the 7” liner after the primary cement job. -60-00 SFD L1 SFD L1 SFD Convert to Injector PBU R-26B PTD:210-025/210-024 Area Of Review: L1 SFD Convert to Injector PBU R-26B PTD:210-025/210-024 Ok.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item la: Classification of Service Wells: Gas Injection, Water Injection, Water - Alternating -Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50- 029 - 20123- 00 -00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

It took a little time to resolve this issue as those hours showed up on the Daily Report, but not on the Operations Summary_ Very odd... Anyway, here is an attachment that will replace the last days work by the rig for this Multilateral Well.

The permit is for a new wellbore segment of existing well PBU R -26B, Permit No. 210- 025, API No. 50- 029 - 21547 -01. Production /injection should continue to be reported as a function of the original API number stated above. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, ova Commission order, or the terms and conditions of this permit may result in the rc oc. ion or suspension of the permit.

(3) All True vertical Depths (TvDSS) are subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, vibration and Downhole weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a Primary Depth control (PDC) log above the Kick off Point of 10092 ft MD from well R -26B dated 04 May 2010 per Cole Able with BP Exploration (Alaska), Inc. The MWD data is now the PDCL for well R- 26BL1. (8) The sidetrack was drilled from R -26A through a milled window in a 7 inch liner. Top of window 9215 ft.MD (8773.4 ft.TVDSS) Bottom of window 9223 ft.MD (8781.3 ft.TVDSS) (9) Tied to R -26A at 9200 feet MD (8758.6 feet TVDSS). (10) Baker Hughes INTEQ run 2 was used to downsqueeze cement to abandon perfs and secure a whipstock. (11) The resistivity interval from 9223 ft. to 9602 ft. MD (8781.3 ft. to 8895.3 ft. TVDSS) was logged on run 5, 11 1/2 hours after drilling. Data has been correlated to drilled gamma ray data and depth shifted +3 feet. (12) Baker Hughes INTEQ runs 9 through 11 were used to drill and run a liner on R -26B. (13) R -26BL1 was drilled as a sidetrack off an aluminum billet set at 10093 feet MD (8783.2 feet TVDSS) on R -26B. (14) The interval from 11825 ft to 11850 ft MD (8810.0 ft. to 8809.3 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
