| Engineer | Form: (04) 401199352 02/13/2017 | 1) Prior to starting repair operations a bradenhead test shall be performed. If the beginning pressure is greater than 25 psi, contact COGCC Engineer for sampling requirements. If pressure remains at the conclusion of the test, or if any liquids were present contact COGCC Engineer for sampling requirements. The Form 17 shall be submitted within 10 days of the test.
2) The additional cement referenced shall be placed as indicated. The placed cement shall be verified with a CBL and documented with a Form 5. |
| Engineer | Form: (04) 401437460 05/23/2018 | This approval is good for one year and a new application must be made before October 23, 2018(1 year from prior application). Updates for the planned utilization of the well should be included with the application.
A Form 5A is required to report all plugs currently downhole which isolate the perforated interval.
The Form 7 reporting must match the actual status of the wellbore.

| Engineer | Form: (06) 403290950 01/17/2023 | 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.

| Engineer | Form: (06) 403290950 01/17/2023 | Operator shall implement measures to control venting, to protect health and safety, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare. |
| Engineer | Form: (06) 403290950 01/17/2023 | 1) Provide 2 business day notice of plugging MIRU via electronic Form 42, and provide 48 hours Notice of Plugging Operations, prior to mobilizing for plugging operations via electronic Form 42. These are 2 separate notifications, required by Rules 405.e and 405.I.
2) Prior to placing the 540’ plug: verify that all fluid migration (liquid and gas) has been eliminated. If evidence of fluid migration or pressure remains, contact COGCC Engineer for an update to plugging orders.
3) After isolation has been verified, pump surface casing shoe plug. If cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at 273’ or shallower and provide 10 sx plug at the surface.
4) Leave at least 100’ of cement in the wellbore for each plug without mechanical isolation.
5) With the Form 6 SRA operator must provide written documentation which positively affirms each COA listed above has been addressed. |
| Engineer | Form: (06) 403290950 01/17/2023 | FLOWLINE AND SITE CLOSURE
1)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.
2)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. |
| OGLA | Form: (06) 403290950 01/23/2023 | Due to close proximity to Residential Building Units (RBUs): prior to commencing operations, at a minimum, the operator will provide an informational sheet to the owners/occupants of RBUs that are nearby and adjacent to the parcel on which the well is located. The sheet will include the operator's contact information and the nature, timing, and expected duration of the P&A operations. |
| OGLA | Form: (06) 403290950 01/23/2023 | Due to close proximity of plugging and abandonment (PA) operations to RBUs BUs, Operator will ensure compliance with maximum permissible noise levels in COGCC Rule Table 423 and install temporary sound walls, straw bales, or other BMPs to dampen noise if necessary. |
