| Engineer | Form: (02) 400353089 12/17/2012 | 1)Provide notice of MIRU via an electronic Form 42.
2)Comply with Rule 317.i and provide cement coverage to a minimum of 200' above the Niobrara. Verify cement coverage with a cement bond log per 317.o.

| Engineer | Form: (04) 402599752 02/22/2021 | 1. Operator will implement measures to control venting, to protect health and safety, and to ensure that vapors and odors from well operations do not constitute a nuisance or hazard to public welfare.
2. Well to be plugged no later than 12/31/2021. Pressure is to be managed and mitigated until plugging is complete. Summary of well monitoring and mitigation will be submitted on a Form 4 Sundry within 30 days of the well being plugged and abandoned but no later than 12/31/2021. The sundry should include monthly pressure monitoring data, flow rate information, sample analysis interpretation, and bradenhead test description.
3. Shut in bradenhead pressure shall not exceed 50 psig. |
| OGLA | Form: (06) 402690791 05/26/2021 | 1. Operator will implement measures to capture, combust, or control emissions 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 health, welfare, and the environment.
2. Operator will review stormwater program and install BMPs and erosion controls as needed to control fine-grained sediment and prevent impacted stormwater runoff from entering surface water and CPW mapped 1202.c High Priority Habitat - Aquatic Native Species Conservation Water buffer along Box Elder Creek and Ireland Reservoir No 5. |
| Engineer | Form: (06) 402690791 05/28/2021 | 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.

| Engineer | Form: (06) 402690791 05/28/2021 | 1) Provide 2 business day notice of plugging MIRU via electronic Form 42.
2) After placing the shallowest hydrocarbon isolating plug (4300'), operator must wait a sufficient time to confirm static conditions.
3) After placing plug at 2600’ assure that all fluid migration has been eliminated by monitoring the well for a minimum of 8 hours before proceeding to the next plug. If at any time after placing this plug there is evidence of pressure or of fluid migration, contact COGCC engineering before continuing operations.
4) Prior to placing the 1100’ plug: verify that all fluid migration (liquid or gas) has been eliminated. If evidence of fluid migration or pressure remains, contact COGCC Engineer for an update to plugging orders.
5) After isolation has been verified, pump plug and displace. If cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at 976’ or shallower and provide at least 10 sx plug at the surface.
6) Leave at least 100’ of cement in the wellbore for each plug.
7) 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.
8) With the Form 6 SRA operator must provide written documentation which positively affirms each COA has been addressed. |
