03/24/2022 | 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) After placing the shallowest hydrocarbon isolating plug (4907'), operator must wait a sufficient time on all subsequent plugs to confirm static conditions. If at any time after placing this plug there is evidence of pressure or of fluid migration, contact COGCC Area Engineer before continuing operations.
8) Plugging procedure has been modified as follows,
Plug #1 - 4022', CIBP with 2 sx of cement
Plug #2 - 2005-1775', 25 sx casing plug.
Plug #3 - 1623', perf and pump 50 sx (+10 sx in the casing). WOC and tag at 1523' or higher if CICR is not used for the squeeze.
Plug #4 - 1125', perf and pump 75 sx (+40 sx in the casing). WOC and tag at 610' or higher if CICR is not used for the squeeze.
Plug #5 - 350', perf and pump 50 sx (+30 sx in the casing). Intention of this plug is to circulate cement to the surface and leave the casing and annulus full.
Plug #6 - 50' of cement at the surface in both the casing and the annulus per COA #5.
NOTE: Plug #2-#5 locations are subject to CBL/GR log that will be run from 2000-0'. Confirm depths with COGCC Area Engineer before perforating.
9) 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. Pursuant to Rule 1105.f. Abandonment Verification, within 90 days of an operator completing abandonment requirements for a flowline or crude oil transfer line, an operator must submit a Field Operations Notice, Form 42-Abandonment of Flowlines for on-location flowlines, and a Flowline Report, Form 44, for off-location flowlines or crude oil transfer lines.

03/24/2022 | 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. |

07/18/2022 | 1) Provide electronic Form 42 Notice of MIRU 2 business days ahead of operations.
2) Prior to starting repair work a bradenhead test shall be performed. If the beginning pressure is greater than 25 psi, or if pressure remains at the conclusion of the test, or if any liquids were present contact COGCC Engineer for sampling requirements before
pumping any cement. The Form 17 shall be submitted within 10 days of the test.
3) If cement is squeezed above the reported TOC, 3209', then the placed cement shall be verified with a CBL and documented with a Form 5 within 30 days of repair operations. For a cement squeeze in the cemented interval, document repair on Form 4 with supporting documentation.
4) After repair, MIT (10 day notice, contact inspector) and submit Form 21 in 30 days. |

04/08/2024 | This oil and gas location is within CPW-mapped High Priority Habitat for Lesser Prairie Connectivity Zone and 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. |
