10/5/2011 | 1) Provide 24 hour notice of MIRU to Jim Precup at 303-469-1902 or e-mail at james.precup@state.co.us.
2) Provide remedial cement from 1150’ to 50’ above surface casing shoe or higher (Fox Hills). Verify coverage with cement bond log.
3) Provide remedial cement from existing TOC to 200’ above Niobrara or submit CBL showing coverage. No CBL on file. Although this APD indicates TOC is at 5500’, calculated TOC based on 125 sx per Form 5 on file is below Niobrara. Verify coverage with cement bond log.

11/27/2019 | Plugging:
1) Provide 48 hour notice of MIRU via electronic Form 42 - Start of Plugging Operations.
2) After placing the shallowest hydrocarbon isolating plug, 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.
3) Shoe plug: Tag plug 50’ above surface casing shoe, if cement does not circulate to surface.
4) Surface plug: Cement from 50' to surface in casing and annulus.
5) With the Form 6 SRA operator must provide written documentation which positively affirms each COA from the approved Notice of Intent to Abandon has been addressed.
Bradenhead:
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. The Form 17 shall be submitted within 10 days of the test.
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.
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.
Venting during plugging:
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.
Flowlines:
Properly abandon flowlines 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.
