| Engineer | Form: (06) 401218272 03/07/2017 | 1) Prior to starting plugging operations a bradenhead test shall be performed. 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) Plug listed as half in-half out surface casing is actually production casing stub plug that will also cover the surface casing shoe. This plug must be tagged at 750’ or 50’ above depth production casing is cut and pulled at, whichever is shallower. 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. Leave at least 100’ cement in the wellbore for each plug. |
