Anticipated Surface Pressure:2420 psi (based on 0.1 psi/ft gas gradient) Last SI WHP:1975 psi (taken on 1/21/25) Min ID:1.90” @ 11,461’ MD Max Angle:104 deg @ 11,170’ MD Well History: 06-12 was drilled and completed in May 1980 as an Ivishak Z4 producer and yielded 7.1MMBO before being reservoir plug and abandoned. 06-12A rig sidetrack was drilled and completed in July 1992 as an Ivishak Z4 producer and yielded 3.1MMBO until being plug and abandoned. 06-12B was 06-12BL1 were drilled and completed in November 2011 as a CTD multilateral Sag producer with slotted liner, which yielded 0.69 MMBO throughout its life. The well target was a part of the Sag gas drive campaign that placed CTD laterals just south of the Sag gas cap enabling gas-drive pressure support to produce black oil through the relatively tight sag formation. Low oil rates were common over most its life mostly due to higher-than-expected water cuts inflowing via nearby faulting connected to the Ivishak. Justification for Reservoir P&A: 06-12B and 06-12BL1 production rates have become marginal with well test results averaging below 50 IOR for the last year. The Sag gas drive target is no longer economic, and no other viable targets can be reached from the existing wellbore without a sidetrack. Objectives: The intent of this program is to perform a reservoir P&A of both 06-12B and 06-12BL1 per 20 AAC 25.112 and cut TBG in preparation for a 2025 I-rig rotary sidetrack. The plan is to set a plug in CTD liner below TSGR, punch the CTD LNR above liner lap TOC, perform a cement squeeze with coil to ensure a greater than 200’ MD continuous lateral cement plug with its base below TSGR (top of pool). After a slickline TOC D&T and AOGCC witnessed pressure testing are complete, E-line will cut TBG below the planned I-rig KOP of ~3300’ MD. 907-575-7336 907-227-8496 RST Res P&A Sundry Well: 06-12B & 06-12BL1 PTD: 211-115, 211-117 Integrity: PPPOT-T to 5000 psi (passed on 1/11/25) PPPOT-IC to 3500 psi (passed on 1/12/25) MIT-T to 2731 psi (passed on 1/23/25) CMIT-TxIA to 2620 psi (passed on 1/23/25) Procedure: Slickline: Drift for Eline CIBP and punch. Eline: 1. Perform HES CBL/GR/CCL form 10,875’ to 10,500’. Send log to OE for confirmation prior to making up punches. 2. Punch 3-3/16’ liner from 10,845-10,850’ MD. Use punches that avoid penetrating the 7” 26# CSG. 3. Bullhead kill with 230 bbls of SW or 1% KCL followed by 38 bbls crude FP. Max pressure 2650 psi. 4. Set CIBP @ 10,855’ MD. 5. Perform injectivity test to 1200 psi with crude to determine LLR down liner lap. Expect minimal injectivity, if any. This is to verify that a liner lap leak won’t impact the subsequent CTU cement squeeze design. Coiled Tubing: 1. MIRU CTU 2. Perform coil flag logging run with GR/CCL. 3. If injectivity down the liner lap is unmanageable, then swap over the wellbore to DSL from TOL to surface. If manageable injectivity, then KCL/SW are adequate. 4. Set one-trip cement retainer at 10,650’ MD in middle of first full joint of 3-3/16” LNR below deployment sleeve. 5. Establish 1:1 returns with flowpath down CT, thru retainer, into punches with returns up liner lap to CT backside. 6. Volumetrically place 10 bbl (8.1 + 1.9 excess) cement plug inside 3-1/16” liner from retainer to punches and outside in 3-3/16” x 7” liner lap annulus from punches to TOL. Unsting, then lay in 2 bbls of cement from top of retainer. This will leave TOC at ~10,375’. 7.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of "Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" boxes are also checked, cross out that erroneous entry and initial it on the Form 10-403. Geologist 2 If the “Abandon” box is checked in Box 15 (Well Status after proposed work) the initial reviewer will cross out that checkbox and instead, check the "Suspended" box and initial those changes. Geologist The drilling engineer will serve as quality control for steps 1 and 2. Petroleum Engineer (QC) 3 When the RA2 receives a Form 10-403 with a check in the "Plug for Redrill" box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." Research Analyst 2 4 When the RA2 receives Form 10-407, they will check the History tab in RBDMS for the IPBRD code. If IPBRD is present and there is no evidence that a subsequent re-drill has been completed, the RA2 will assign a status of SUSPENDED to the well bore in RBDMS. The RA2 will update the status on the 10-407 form to SUSPENDED, and date and initial this change. If the RA2 does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. Research Analyst 2 5 When the Form 10-407 for the redrill is received, the RA2 will change the original well's status from SUSPENDED to ABANDONED. Research Analyst 2 6 The first week of every January and July, the RA2 and a Geologist or Reservoir Engineer will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all Plug for Redrill sundried wells have been updated to reflect current status. At this same time, they will also review the list of suspended wells for accuracy and assign expiration dates as needed.

The purpose was to fix integrity problems with the well and provide a profile modification. The well was completed with 4-1/2" chrome tubing and a 7" chrome liner and initially only had pens in Zone 4. The perforations were squeezed and re-perfed in preparation for a Zn 4 frac job which increase oil production in 1993. Later in 1994, the sag was frac'd which increase oil production that steadily dropped to low rates as water cut climbed. The well is in sound mechanical condition. It passed an MIT-IA to 3000 psi and MIT-OA to 2000 psi (April 2011). The March 2010 Caliper shows the 4W tubing to be in good condition, some scale like deposits at -10,030' and to 10,410' and restricting the ID to 3.61" at 10,154' md. With respect to the 7" liner, it appears to be in good/fair condition with max wall penetration of 25% at 10,745' md. This well has been cycled several times with no real recovery converting this well into a low value Ivishak producer. The proposed CTD Sidetrack is a horizontal dual lateral Sag River producer which will provide offtake in a fault block located in Southern Drill Site 6. The multilateral sidetrack, 06-12B & BL1, is scheduled to be drilled by Nordic 2 starting on October 20th, 2011 targeting the Saq River formation. The pre rig includes setting a thru-tubing whipstock, milling XN Nipple, and squeezing perforations. With the whipstock set and perforations abandoned, Nordic 2 will mill a window off of the mechanical whipstock allowing a kick off in the Shublik formation. This sidetrack will make a 41 DLS build to land in the Sag River formation. Then a 3-3/16" protection string will be run (and cemented in place if Zn 4 Ivishaks encountered) to cover the Shublik formation. Then, the 3-3/16" shoe will be drilled out and drilling will continue via 12 DLS to the planned 06-12B TD which will be completed with a 2-3/8" slotted liner with billet on top. Finally, the 06-12B L1 will be drilled by kicking off the 06-12B slotted liner top billet and will be completed with 2-3/8" slotted liner brought back into the 3-3/16" protection string. The following describes the planned work. A schematic diagram of the proposed sidetrack is attached for reference.
