07/28/2017 | Plugging
• Provide 48 hour notice of plugging MIRU via electronic Form 42.
• Surface casing shoe already isolated with primary cement. Production casing stub plug will be inside of surface casing and if plug is not circulated to the surface then the plug shall be tagged. Max depth to top of stub plug is 50’ above the depth of the casing cut, 530' or shallower for the planned cut at 580’.
• After pumping stub plug wait on cement per design and monitor for fluid migration. Contact COGCC Engineer for revised plugging plans if well builds pressure when shut in, prior to pumping next plug.
• Run CBL on surface casing from 580-0'. Contact COGCC Engineer for revised plugging plans if cement bond log shows any area of bond that is less than expected, a very good bond throughout..
• Place a 25 sack plug at the surface, all other plugs shall have at least 100' of cement
left in the casing.
• Properly abandon flowlines as per Rule 1103.

07/28/2017 | Bradenhead Testing
Prior to starting plugging operations, a bradenhead test shall be performed. If the initial
shut-in bradenhead pressure is greater than 25 psi, notify COGCC Engineer for
sampling requirements prior to beginning the test. Sampling shall comply with Operator
Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and
Gas Sampling.
