1/15/2018 | Plugging
• Provide 48 hour notice of plugging MIRU via electronic Form 42.
• Per operator request corrected casing cut depth to 1350'. Stub plug will be 1450-1250 and tagged.
• If there is fluid migration or shut-in pressure on the well prior to pumping any plug(annular or casing) that isolates deepest aquifer or the surface casing shoe (whichever is deeper) contact COGCC Engineer for revised plugging orders.
• If the shoe plug, or combined stub/shoe plug, is not circulated to the surface then the plug shall be tagged and must be 50’ into the shoe, or 50’ above the cut, whichever is shallower.
• Place a 50' plug(minimum) at the surface, all other plugs shall have at least 100' of cement left in the casing.
• Properly abandon flowlines as per Rule 1103. |

Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. |
