5/6/2010 | 1) Note surface casing setting depth change from 1100’ to 1110’. Increase cement coverage accordingly and cement to surface. 2) Provide 24 hour notice of MIRU to Jim Precup at 303-469-1902 or e-mail at james.precup@state.co.us 3) Comply with Rule 317.i and provide cement coverage from TD to a minimum of 200' above Niobrara and from 200’ below Sussex to 200’ above Sussex. Verify coverage with cement bond log. 4) Comply with Rule 321. Run and submit Directional Survey from TD to base of surface casing. Ensure that the wellbore complies with setback requirements in commission orders or rules prior to producing the well. |

2/23/2018 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Properly abandon all flowlines as per Rule 1103. File electronic Form 42 once abandonment complete.
3) Operator shall implement measures to control unnecessary and excessive venting, to protect the health and safety of the public, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare.
4) Plug listed as half in-half out surface casing is actually production casing stub plug that will also cover the surface casing shoe. This plug must be tagged at 650’ or 50’ above depth production casing is cut and pulled at, whichever is shallower. |

2/23/2018 | 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.
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. |
