2)After placing the 5800' plug: WOC 4 hours and tag plug – top of plug must be not deeper than 5600' nor higher than 5400'.
3) Prior to cutting casing or placing the 2050' 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, cut and pull casig, pump 2050' plug and displace.
4) For 1000’ plug, 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 361’ and provide minimum 20 sx plug at the surface. Leave at least 100’ of cement in the wellbore for each plug.
5) Properly abandon all flowlines. Once flowlines are properly abandoned, file electronic form 42. |
