12/03/2024 | This oil and gas location is within 0.5 miles of a Rule 1202.c.(1) Ferruginous Hawk nest area High Priority Habitat. Operator consultation with CPW is required by 1202.c.(2)B.ii and is necessary prior to Form 6 approval. Please note that non-emergency plugging and abandonment (PA) activities should not take place from February 1 to July 15, pre construction surveys may be required. |

12/16/2024 | Plugging Procedure Conditions of Approval
1) Provide electronic Form 42 Notice of MIRU 2 business days ahead of operations and electronic Form 42 Notice of Plugging Operations 48 hours prior to mobilizing for plugging operations.
2) Plugs and squeezes will be placed as stated in the Plugging Procedure section of the approved NOIA unless revised by COA or prior approval from ECMC is obtained.
3) The wellbore must be static prior to placing cement plugs which are to be a minimum of 100' in length for all but surface plugs. Mechanical isolation requires a 25' cement plug, minimum. For plugs not specified to be tagged, a tag is required if circulation is not maintained while pumping plug and displacing to depth. Wait on cement(WOC) a minimum of 4 hrs before tagging a plug. Tag at tops specified. Notify ECMC Area Engineer of a high(shallow) tag or before adding cement to a previous plug due to a low(deep) cement top.
4) Place a 50' plug (minimum) at the surface, both inside the inner most casing and in all annular spaces. Surface plugs shall be circulated to surface. Confirm cement to surface and complete isolation in all strings during cut and cap. After cut and prior to cap, verify isolation by either a 15 minute bubble test or 15 minute optical gas imaging observation. If there is any indication of flow contact ECMC Engineering before proceeding. Provide a statement on the 6 SRA as to which method was used and what was observed. Retain records of final isolation test for 5 years.
5) With the Form 6 SRA operator must provide written documentation which positively affirms each COA has been addressed.
6) Operator must wait a sufficient time on all plugs to achieve the intended design. If at any time during the plugging there is evidence of previously unreported pressure or fluid migration, contact ECMC Area Engineer before continuing operations.
7) Plugging procedure has been modified as follows,
Previous CIBP abandonment plugs set at 6895' on 12/1/2020 w/ 3 sx to remain,
Plug #1 - 6120-5600', 75 sx cement casing plug,
Plug #2 - 3590', perf and squeeze 50 sx of cement through a CICR set at 3510', spot 10 sx of cement on top of the CICR,
Plug #3 - 1650', perf and squeeze 195 sx of cement through a CICR set at 1000', spot 10 sx of cement on top of the CICR,
Plug #4 - 657', perf and squeeze 60 through a CICR set at 607', spot 20 sx of cement on top of the CICR,
Plug #5 - 50', perf and circulate 20 sx of cement to the surface.

12/16/2024 | Properly abandon flowlines per Rule 1105. If flowlines will be abandoned in place, include with the Form 27: pressure test results conducted in the prior 12 months as well as identification of any document numbers for a ECMC Spill/Release Report, Form 19, associated with the abandoned line.

12/16/2024 | Consistent with Rule 911.a, a Form 27 must be approved prior to cut and cap, conducting flowline abandonment, or removing production equipment. Allow 30 days for Director review of the Form 27; include the Form 27 document number on the Form 44 for offsite flowline abandonment (if applicable) and on the Form 6 Subsequent.

12/16/2024 | Bradenhead Testing
Prior to starting plugging operations a bradenhead test shall be performed if there has not been a reported bradenhead test within the 60 days immediately preceding the start of plugging operations.
1) If, before opening the bradenhead valve, the beginning pressure is greater than 25 psi, sampling is required.
2) If pressure remains at the conclusion of the test, or if any liquids were present during the test, sampling is required.
The Form 17 shall be submitted within 10 days of the test. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions. If samples are collected, copies of all final laboratory analytical results shall be provided to the ECMC within three (3) months of collecting the samples.
If there is a need for sampling, contact ECMC engineering for verification of plugging procedure.
