11/07/2017 | 1) Submit Form 42 electronically to COGCC 48 hours prior to MIRU.
2) Prior to placing the 750’ 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.
3) 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 270’ and provide minimum 10 sx plug at the surface. Leave at least 100’ of cement in the wellbore for each plug.
4) Properly abandon flowlines. Once flowlines are properly abandoned, file electronic form 42. |
