05/18/2018 | Prior to starting plugging operations a bradenhead test shall be performed.
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 a confirmation of plugging requirements prior to placing any plugs.
4) Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions. The Form 17 shall be submitted within 10 days of the test.
5) Submit Form 42 electronically to COGCC 48 hours prior to MIRU
6) Prior to cutting casing or placing the 581’ 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 requirements.
7) After isolation has been verified, pump plug and displace. If cement is not circulated to surface, shut-in, WOC 4 hours and tag plug – top of plug must be not deeper than 281’ and provide minimum 10 sx plug at the surface.
8) Leave at least 100’ of cement in the wellbore for each plug.
9) 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. |
