03/26/2015 | 1) Verify existing cement with a cement bond log. Use CBL results to verify the setting depth of and stage cement pumped through the DV tool. Contact COGCC with CBL results to deetermine if additional aquifer coverage is needed.
2) If Niobrara coverage not present, provide remedial cement 200’ above Niobrara (minimum cement top of 6800’).
3) The additional cement referenced shall be placed as indicated and comply with Rule 317.j. The placed cement shall be verified with a CBL and documented with a Form 5 Drilling Completion Report.
4) Please submit gyro survey data with Form 5 Drilling Completion Report. |

10/24/2019 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Prior to placing the 850' 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 83' 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 (6940'), 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. |

10/24/2019 | 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. |
