04/06/2010 | 1) Note surface casing setting depth change from 800’ to 840’. 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. 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. |

03/20/2017 | 1) Form 17 dated 01/18/2017 indicate that samples were collected. If samples were not collected, prior to plugging collect bradenhead and production gas samples for laboratory analysis. The gas analysis shall be for composition and stable carbon isotopes. If liquid is encountered in the bradenhead then collect samples, analysis of the liquid samples shall be conducted to provide an evaluation of the liquid source. Copies of all final laboratory analytical results shall be provided to the COGCC within three months of collecting the samples in an approved electronic data deliverable format.
2) Provide 48 hour notice of plugging MIRU via electronic Form 42.
3) Properly abandon flowlines as per Rule 1103. File electronic Form 42 once abandonment complete.
4) Please submit gyro survey data with Form 6 Subsequent Report of Abandonment.
5) If plug on CICR at 2070' is not circulated to surface then tag plug – must be 819’ or shallower and provide a 15 sack plug at the surface. Leave at least 100’ of cement in the wellbore for each plug. |

11/27/2017 | 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.
3) If sampling is required contact COGCC engineering for an 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.

11/27/2017 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Prior to placing the 2070’ 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 869 or shallower and provide 10 sx plug at the surface. Leave at least 100’ of cement in the casing for each plug.
4) Properly abandon flowlines as per Rule 1103. File electronic Form 42 once abandonment is complete.
