12/06/2018 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Prior to placing the 751' plug: verify that all fluid migration (liquid or gas) has been eliminated. If evidence of fluid migration or pressure remains, contact COGCC Engineer for an update to plugging orders.
3) After isolation has been verified, pump plug and displace. If cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at 96' or shallower and provide 10 sack plug at surface.
4) Leave at least 100’ of cement in the wellbore for each plug.
5) Properly abandon on-location flowlines as per Rule 1105. File electronic Form 42 once abandonment is 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) If, before opening the Bradenhead valve, the beginning pressure is greater than 25
psi, sampling is required.
2) If pressure remains at the conclusion of the test, or if any liquids were present during
the test, sampling is required.
3) If sampling is required contact COGCC engineering for an confirmation of plugging

Before placing 2-7/8" second string and cementing in place.
1) Provide minimum of 200' of cement above the Niobrara top. (minimum 6810')
2) Provide coverage for Fox Hills and shallower aquifers - 100 sx at 1575'; 300 sx at 900'
3) Repaired 4-1/2" casing shuld be pressure tested (>300#)after drilling out remedial plugs, if pressure test fails - COGCC should be contacted prior to running new second string. |
