3/22/2019 | Plugging
• Provide 48 hour notice of plugging MIRU via electronic Form 42.
• Plugs and squeezes will be placed as stated in the Plugging Procedure section of the approved NOIA unless revised by COA or prior approval from COGCC is obtained.
• COGCC does not have a current Form 17 on file. If there is any bradenhead pressure reported on the pre-plugging Form 17, contact COGCC Area Engineer for revised plugging orders prior to continuing with plugging operations.
• COGCC Change: Move casing cut to 2500’, open hole plug to 2500-2300’.
• Check for fluid migration or shut-in pressure on the well prior to pumping any plug(open hole, annular or casing) that isolates deepest aquifer or the surface casing shoe (whichever is deeper). Contact COGCC Area Engineer for revised plugging orders if well is not static at this time prior to continuing with plugging operations.
• Tag required if the shoe plug, or combined stub/shoe plug, is not circulated to the surface. Shoe plug shall be placed as specified herein and the top of cement must be a minimum 50’ into the shoe, or 50’ above the stub (if not cut below the shoe), whichever is shallower.
• Place a 50' plug (minimum) at the surface, both inside the inner most casing and in all annular spaces. All other cement plugs, without mechanical isolation, shall have at least 100' of cement left in the casing. Confirm cement to surface in all strings during cut and cap.
• Properly abandon flowlines as per Rule 1105. File electronic Form 42 once abandonment 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.

1) The initial pressure measurement on the bradenhead is greater than 25 psi, prior to blowing down any liquid or gas from the bradenhead valve, or
2) Pressure remains at the conclusion of the test, or
3) Any liquids are present anytime during the test. If so, then stop the test as soon as liquids are present and sample before resuming the test.
• Form 17 Bradenhead Test Report shall be submitted within 10 days of the test.
• If samples are collected, copies of all final laboratory analytical results shall be provided to the COGCC within three (3) months of collecting the samples. Submit via a Form 43 to upload the laboratory results to the COGCC Environmental Database. Form 43 instructions are on COGCC’s website under Regulation => Forms => Form 43 COGCC Environmental Database.
