On 2/29/2016, CTD operations were shut-down due to hole stability issues in the drilling of the 16-15A sidetrack. After drilling to ~12600’ MD the rig made a long wiper trip to the window, but upon running back in hole CTD was unable to get past a collapsed shale interval at 11040’ MD. Approval to suspend the well was granted on 2/23/2017. A tubing tail plug was set at 10624’ MD and the well passed a CMIT-TxIA to 2463 psi on 3/13/2017. In the original request for suspension on 1/13/2017, the operator at the time committed to re-sidetracking or reservoir abandoning the well within 5 -years of suspension approval. No progress has been made on either option. The Ivishak confining interval is bound between the THRZ at 10516’ MD and the BHRZ at 10764’ MD. Volumetric TOC outside of the 9.625” production casing with a 30% washout is calculated at 9376’ MD. Cementing of the 7” liner in the original 16-15 bore went to plan with the plug bumped, full returns and cement stringers seen from 10165’ MD to 10574’ MD indicating 7”x 9.625” annulus is fully cemented from the shoe at 10789’ MD to the 7” liner tieback at 10574’ MD. A fullbore reservoir abandonment through a cement retainer set at 10480’ MD was attempted on 4/7/2025. Injectivity through the retainer was lost as soon as cement hit the retainer, leaving TOC in the tubing at 7782’ MD. Current Status: 16-15A is currently not operable and offline. TOC in the tubing is at 7782’ MD. Objectives: The intent of this program is to remove the cement left in the tubing due to a failed fullbore reservoir abandonment attempt in early 2025. After this is completed, we plan to reservoir abandon the 16-15A open hole sidetrack by setting a cement retainer in the tubing tail at ~10490’ MD and pumping cement through the retainer with coiled tubing, creating a lateral barrier across all tubulars and annuli within the confining zone from 10656’-10764’ MD. This scope of work is required by the AOGCC for continued suspension status of the well as a future rig sidetrack candidate. Variance Request: A variance is requested to the plugging requirements under 20 AAC 25.112(a)(1). Due to the inability of CTD to access the open hole below 11040’ MD, it is unknown if cement will be placed along the entirety of the open hole bore. By cementing the 7” liner below the WLEG, a lateral plug will be placed across all tubulars and annuli within the confining zone from 10656’-10764’ MD, this will provide isolation of the reservoir and prevent vertical movement of fluid within the wellbore.

Could you provide more insights on why the well locked up? I believe there was another recent early lockup during a fullbore cement P&A using a NS balldrop cement retainer. Given a sufficient tag of TOC and pressure test this will satisfy as a reservoir plug and you can move forward with suspension.

This schematic shows the planned TOC in the tubing which was supposed to be right at the ball drop retainer at 10480’ MD. The well locked up 36 bbls short of our displacement target, leaving TOC at ~8100’ in the tubing. My calc puts TOC at 8114’ MD, field is calling it at 8092’ MD in the report, we will get the actual depth with the SL tag. This puts the bottom of cement at ~10707’ MD by my calcs. This results in a lateral plug across all strings from 10516-10707’ MD= 191’ MD. SL is currently out on the well pulling the upper GLV to get some additional freeze protect in the tubing This schematic shows the current cement in place. Assuming that we get a good TOC tag and a passing pressure test, are we good with the scope of work completed to call this a sufficient reservoir plug and move forward with the suspension renewal request?

In the original program the phenolic ball was dropped, then chased with 2 bbls of cement and then followed by the foam ball, leaving the TOC in the tubing at 10480’ MD. Instead we would like to move the retainer up to 10480’ MD, pump the 41 bbls of cement and then follow that with the phenolic and foam ball together. This will leave TOC at the same spot in the tubing (10480’ MD), but is operationally simplified, not having to do 2 ball drops and aligns with how these jobs have been recently executed. I highlighted the requested changes in yellow in the new program. Let me know if you approve.

On 2/29/2016, CTD operations were shut-down due to hole stability issues in the drilling of the 16-15A sidetrack. After drilling to ~12600’ MD the rig made a long wiper trip to the window, but upon running back in hole CTD was unable to get past a collapsed shale interval at 11040’ MD. Approval to suspend the well was granted on 2/23/2017. A tubing tail plug was set at 10624’ MD and the well passed a CMIT-TxIA to 2463 psi on 3/13/2017. In the original request for suspension on 1/13/2017, the operator at the time committed to re-sidetracking or reservoir abandoning the well within 5 -years of suspension approval. No progress has been made on either option. The Ivishak confining interval is bound between the THRZ at 10516’ MD and the BHRZ at 10764’ MD. Volumetric TOC outside of the 9.625” production casing with a 30% washout is calculated at 9376’ MD. Cementing of the 7” liner in the original 16-15 bore went to plan with the plug bumped, full returns and cement stringers seen from 10165’ MD to 10574’ MD indicating 7”x 9.625” annulus is fully cemented from the shoe at 10789’ MD to the 7” liner tieback at 10574’ MD. Current Status: 16-15A is currently not operable and offline. A PX plug is set in the tubing tail at 10624’ MD. Objectives: The intent of this program is to reservoir abandon the 16-15A open hole sidetrack by setting a cement retainer in the tubing tail at ~10610’ MD and pumping a fullbore cement job through the retainer, leaving ~130’ MD of cement on top of the retainer, creating a lateral barrier across all tubulars and annuli within the confining zone from 10656’-10764’ MD. This scope of work is required by the AOGCC for continued suspension status of the well as a future rig sidetrack candidate. Variance Request: A variance is requested to the plugging requirements under 20 AAC 25.112(a)(1). Due to the inability of CTD to access the open hole below 11040’ MD, it is unknown if cement will be placed along the entirety of the open hole bore. By cementing the 7” liner below the WLEG, a lateral plug will be placed across all tubulars and annuli within the confining zone from 10656’-10764’ MD, this will provide isolation of the reservoir and prevent vertical movement of fluid within the wellbore.

The well is located within the Prudhoe Bay Unit on Drill Site 16, and is accessible by road. A passing MIT -IA to 2500 psi on 7/23/15 showed that the well is mechanically sound. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is safe and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured or depleted. This well has potential as a future sidetrack candidate. Condition of the Wellhead and Surface Location PBU 16-15 is located on an active gravel pad. The area surrounding the well is clean gravel. The surrounding area is in good condition and there is no discoloration and no sheen on the pad, pits or in the nearby water. The well is equipped with a wellhead and tree, allowing for pressure monitoring. Request BPXA requests approval for suspension status of PBU 16-15 upon slickline setting a tubing tail plug at 4-1/2" HES X -NIP at 10,624' MD. The integrity of the plug will be demonstrated by a CMIT-TxIA to 2275 psi. The intent is to secure the well with a tubing tail plug to leave -5 years to either CTD sidetrack or plug the well for more permanent suspension. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to be suspended. There are no underground sources of fresh water in this area.
