If the beginning pressure is greater than 25 psi, or if pressure remains at the conclusion of the test, or if any liquids were present contact COGCC Engineer for sampling requirements. The Form 17 shall be submitted within 10 days of the test.
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) CIBP proposed at 3950’, TOC at 3925’. Do not set CIBP any shallower than 3950’ to ensure there is backside cement.
5) Production casing stub plug is also surface casing shoe plug. After pumping stub/shoe plug, shut down and wait on cement at minimum 4 hours; verify gas migration has been eliminated. If evidence of gas migration or pressure remains contact COGCC Engineer for an update to plugging orders. Plug must be tagged at 550’ or shallower. Leave at least 100’ cement in the wellbore for each plug. |
