Engineer | Form: (02 ) 400247776 2/21/2012 | 1)Provide 48 hour notice of MIRU to Mike Hickey via e-mail at mike.hickey@state.co.us or via an electronic Form 42.
2)Comply with Rule 317.i and provide cement coverage from the end of the production casing to a minimum of 200' above the Niobrara and from 200’ below Sussex to 200’ above Sussex. Verify coverage with a cement bond log.
3)Comply with Rule 321. Run and submit Directional Survey from the TD to surface. Ensure that the wellbore complies with setback requirements in commission orders or rules prior to producing the well.

Engineer | Form: (06 ) 402120256 8/8/2019 | 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 ) 402120256 8/8/2019 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Prior to placing the casing shoe 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.
3) 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 804' or shallower and provide 10 sack plug at surface.
4) Leave at least 100’ of cement in the wellbore for each plug.
5) Properly abandon on-location flowlines as per Rule 1105. File electronic Form 42 once abandonment is complete. Within 30 days of an operator completing abandonment requirements for an off-location flowline or crude oil transfer line, the operator must submit a Flowline Report, Form 44.
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 (4200'), operator must wait a sufficient time to confirm static conditions. If at any time after placing this plug there is evidence of pressure or of fluid migration, contact COGCC engineering before continuing operations. |
Engineer | Form: (06 ) 402120256 8/8/2019 | If there has not been a reported Bradenhead test within 60 days of plugging this well, prior to starting plugging operations, a Bradenhead test shall be performed.
1) If, before opening the Bradenhead valve, the beginning pressure is greater than 25
psi, sampling is required, and the COGCC engineering staff must be contacted.
2) If pressure remains at the conclusion of the test, or if any liquids were present during
the test, sampling is required.
3) If sampling is required contact COGCC engineering for a confirmation of plugging
requirements prior to placing any plugs.
Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting
Instructions.
The Form 17 shall be submitted within 10 days of the test. |
Engineer | Form: (06 ) 402120256 8/8/2019 | No CBL on file. CBL to be run prior to plugging to verify stage tool setting depth and existing coverage - submit to COGCC for verification of plugging orders. |
Engineer | Form: (06 ) 402120256 8/8/2019 | WITH KNOWN BRADENHEAD PRESSURE
The plug at 1280' needs to be split into 2 plugs with the 1st being a casing stub plug and have an 8 hour WOC to assure that all fluid migration has been stopped. If that doesn’t isolate the flow, additional attempts in front of the surface shoe plug will need to be attempted. Other downhole potential squeeze opportunities may need to be looked at before placing the plug into the surface casing shoe. |
Engineer | Form: (04 ) 402129947 9/9/2019 | 1. Operator shall 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. Prior to starting bradenhead abatement, if a sample has not been collected within the last twelve months collect bradenhead and production gas samples for laboratory analysis. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. Copies of all final laboratory analytical results shall be provided to the COGCC within three months of collecting the samples.
3. Bradenhead gas is not to be vented to atmosphere; any gas from the Bradenhead will be routed to an enclosed tank and/or combustor. Operator shall implement measures to get an initial estimate of the gas flow rate and/or volume from the bradenhead. The abatement program may be used for six consecutive months.
4. Operator will submit a Form 42 (“OTHER”) stating that “bradenhead abatement program has started.”
5. At the conclusion of the six months, conduct a new bradenhead test and submit the Form 17 within ten days of the test and submit a Form 4 Sundry that summarizes current well condition. The sundry should include details of the future plans and the flow rate information and pressure data.
