May 2013 a RWO was executed to cut and pull the 9-5/8” casing from 1,702’. A 7” tieback was installed and the 7” x 9-5/8” x 13-3/8” was cemented to surface. The 7” has a slip-lock wellhead at surface. LEL’s were detected above the conductor in 2023 and the well was SI and made not operable. October 2024 a wellhead repair was executed where essentially the 13-3/8” was cut away 20” below the bottom flange of the wellhead and a cap was welded containing the cemented OA. The well was POP’d post repair and showed signs of re- pressurzation. A WellLock treatment was pumped 12/20, 7 gallons total to a max treatment pressure of 1400 psi before locking up. A follow up retreat was pumped 1/24/25, ¼ gallon was pumped @ a treatment pressure of 2500 psi for 30 minutes followed by sustained cure pressure of 1500 psi. Upon POP’ing the OA pressure was stable until the heater was removed from the wellhouse, OA pressure would then increase. After the UE flowback period it was decided to shut the well in due to pressure still building up. Objective: Retreat OA with WellLock Procedure: DHD – Heater required in wellhouse multiple days in advance of treatment to get everything to a warm constant temperature. 1. Blead pressure off OA gauge risers if > 0 psi. 2. Remove pressure gauge risers @ from OA cap. 3. Remove as much WellLock as possible accessing from the pressure riser bung 4. Re-install OA gauge risers & PT to 1,000 psi with Nitrogen. - Monitor for external leaks. - Previous PT post top hat installation to 1,000 psi saw pressure decrease to 540 psi in 15 minutes with no external leaks detected. 5. Pump WellLock retreatment to a treatment pressure of a minimum of 1000 psi – Discuss with OE prior to determine treatment pressure and duration along with cure pressure. - UT data from 11/25/24 of 7” showed lowest wall thickness reading to be 0.349” v 0.408” nominal (115% wall loss, derated collapse = 4774 psi) & 13-3/8” to be 0.478” v 0.514” nominal (77% wall loss, derated burst = 4,003 psi) 6. After Sample has set up, POP U/E & Monitor & bleed as necessary for 28 days. 7. Retreat with WellLock if necessary.

Well is gas lifted and produces ~6000 bwpd, 150 bopd, and ~40 IOR. In May 2013 a RWO was completed to cut and pull the 9-5/8” casing from 1702’. A 7” tieback was installed and the 7” x 9-5/8” and 13-3/8” was cemented to surface and the 7” has slip-lock wellhead at surface. A casing excavation repair was completed to seal the fully cemented 7” x 13-3/8” casing annulus. The well was excavated less than two feet and plate patch welded between the competent 7” and 13-3/8” casings. Two 1” weldolet were placed in the plate repair to allow for monitoring and treating if needed. The well was POP’d post surface casing repair and the OA repressurization was not manageable by bleeds. Current Status: X-10A is currently under evaluation starting 12/9/2024. Objective: Squeeze OA with Well Lock (or similar) to repair OA repressurization.

Sweep gas, Load IA and tbg, bullhead to perfs a. 475 bbl crude 2. Set TTP 9917’ MD and CMIT-TxIA to 2500 psi 3. Bleed tubing and IA pressures to 0 psi, rig up IA companion valve 4. Evacuate crude in IA below the conductor cut area (~47” below grade) 5. Rig up fittings for N2 purge across IA and companion IA valve 6. Disconnect well 7. Pull well shelter and floor kit 8. Complete ACWR Well Repair Procedure: 1. Excavate 17” which equates to 47” below grade, avoid confined space Sundry Work (Approval required to proceed) Surface Casing Repair 2. Cutconductor as close to cellar floor as possible (assumption is 6” from cellar floor), remove cement 3. Cut 13-3/8” casing 12” above conductor cut, remove cement a. See diagram below Passing CMIT- TxIA required to proceed. - mgr Excavation Weld RepairWell:X-10APTD:215-004 Excavation Weld Repair Well:X-10A PTD:215-004 4. Remove additional cement between the 13-3/8” and 7” casing, to furthest extent possible, ideally 12” (this is to avoid heat sink issues when preheating the weld areas for the 13-3/8” wedding bands) 5. Rig up N2 purge, monitoring purge return for LELs 6. Weld 13-3/8” casing band a. Fit up of band will be determined by welder input on plate fit up between bands b. L-80 to X65 API 5L 7. Fit up 7” casing band and adjust so that a ½” pl ate can be welded between the rings while ensuring there is at least 12” between the lower casing spool and 7” band (to allow sufficient room for pre- heating, 12” is needed) a. L-80 to X65 API 5L 8. Stencil template for ½” plate and fab plate with CNC 9. Weld 2, ½” thredolets onto top of plate for future pressure gauge and plug 10. Fit up plate and weld a. X65 API 5L to A572 11. NDE Welds a. UT wedding bands b. MT Plate 12. Install Well shelter and floor 13. Reconnect Well Post Welding – DHD 1. Low pressure test with nitrogen to 150 psi. Use 4-way meter to confirm competent OA at surface. 2. OA integrity test with diesel to 1200 psi. Slickline 1. Pull TTP 2. Turn well over to Operations to bring online under evaluation. Consider placing a nitrogen cap on OA before POP’ing or POP’ing with an open bleed to mitigate the liquid packed annulus concern. Operations 1. Set MOASP to 1000 psi and install wireless gauges for monitoring 2. Check pressures regularly as the well comes online and bleed accordingly to determine behavior of newly re-established OA. 3. Well Integrity coordinator to track OA behavior and make ‘Operable’ if the well stays online within acceptable criteria. If well does not behave within acceptable criteria, then a well-lock squeeze will be planned and pumped at a future time.

I have sent an email to the CTD group to ensure that we report our reservoir pressure in our permits from the deepest planned TVDss along the well path and not the 8,800 TVDss datum. Thank you.

But reporting the maximum reservoir pressure at 8800' ss versus at TD is significant with reservoir pressure and MPSP at TD being the worst case scenario. In the case of X-10,the MPSP and max res pressure are 74 psi higher at TD versus ss. What do you think?

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.
