05/16/2023 | Plugging
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 COGCC 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. Tag at tops specified or shallower. Notify COGCC Area Engineer before adding cement to previous plug.
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 in all strings during cut and cap.
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 COGCC Area Engineer before continuing operations.
7) Plugging procedure has been modified as follows,
Plug #1 - 4528', CIBP with 4 sx of cement. MSSP
Plug #2 - 3925', perf and squeeze 35 sx into the CICR at 3875'. Leave 6 sx on top of the CICR. MRTN
Plug #3 - 3200', perf and squeeze 35 sx into the CICR at 3150'. Leave 6 sx on top of the CICR. SHWNE
Plug #4 - 1550', perf and squeeze 80 sx into the CICR at 1500'. Leave 6 sx on top of the CICR. CYNN
Plug #5 - 750', perf and squeeze 35 sx into the CICR at 700'. Leave 6 sx on top of the CICR. DKTA
Plug #6 - 294', perf and circulate 81 sx of cement to surface. If perfs will take fluid but do not circulate or circulation is lost, pump a minimum of 50 sx and displace to 144', 100' above the surface shoe, WOC and tag. Notify COGCC Area Engineer of insufficient cement prior to pumping additional plugs.
Plug #7 - 50' of cement at the surface in both the casing and the annulus per COA #4.
8) Submit corrected WBD to correspond with approved 6(N) prior to filing Form 42 Notifications required in COA #1 above. |

05/16/2023 | 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 COGCC Spill/Release Report, Form 19, associated with the abandoned line. |

05/16/2023 | 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. |

05/16/2023 | 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 COGCC within three (3) months of collecting the samples.
If there is a need for sampling, contact COGCC engineering for verification of plugging procedure. |

07/24/2023 | This oil and gas location is within CPW-mapped High Priority Habitat for Lesser Prairie Chicken Estimated Occupied Range and Lesser Prairie Chicken Focal Area. Plugging and abandonment (P&A) activities should not take place from March 1 to July 15. If site conditions warrant that P&A activities must occur between March 1 and July 15, the operator will consult with CPW to develop site specific avoidance, minimization, or mitigation measures prior to conducting any activities. |
