7/28/2022 | This oil and gas location is within CPW-mapped High Priority Habitat for Lesser Prairie Chicken Estimated Occupied Range. 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. |

8/9/2022 | 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) Contact COGCC Area Inspector prior to commencing plugging operations.
3) 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.
4) 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.
5) 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.
6) With the Form 6 SRA operator must provide written documentation which positively affirms each COA has been addressed.
7) Plugging procedure has been modified as follows,
Plug #1 - 5150', CIBP
Plug #2 - 5100', CIBP with 2 sx of cement.
Plug #3 - 2255', perf and squeeze 50 sx, leave last 12 sx in casing. See COA #4 for tag requirement.
Plug #4 - 1737', perf and squeeze 50 sx, leave last 12 sx in casing. See COA #4 for tag requirement.
Plug #5 - 675', perf and circulate 100 sx. Displace to 400', WOC and tag, must be at 400' or shallower.
Plug #6 - 50' of cement at the surface in both the casing and the annulus, see COA #5 for placement requirement.
8) Properly abandon flowlines as per Rule 1105. Pursuant to Rule 911.a. Closure of Oil and Gas Facilities, Operator will submit Site Investigation and Remediation Workplans via Form 27 for COGCC prior approval before cutting and capping the plugged well, conducting flowline abandonment, and removing production equipment.
9) Submit CBL with Form 6 SRA if available. |

8/9/2022 | 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. |
