03/19/2014 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) No CBL on file. Run CBL to verify the top of primary cement is at least 200’ over Niobrara, at least 50’ below Sussex to 200’ above Sussex, and adequately isolates the Fox Hills aquifer. If cement does not exist as required, provide this coverage as part of this plugging project. Use CBL results to verify the stage cement pumped from 715' to 405'. If cement missing, add cement behind production casing or cut casing deeper and add cement to ensure Fox Hills aquifer isolation.
3) If unable to pull casing contact COGCC for plugging modifications.
4) For 380' plug: pump plug and displace, shut-in, WOC 4 hours and tag plug – must be 209’ or shallower.
5) Properly abandon flowlines as per Rule 1103. File electronic Form 42 once abandonment complete.
