2) Run CBL to verify the top of primary or squeezed cement is at least 200’ over Niobrara and adequately isolates the Shannon/Sussex and aquifer. If it does not exist as required, provide this coverage as part of this plugging project. Use CBL results to verify the setting depth of and stage cement pumped through the DV tool. If DV cement shallower than 830' email copy of CBL to COGCC and contact COGCC for possible change in plugging orders.
3) If CBL shows DV tool cement does not reach surface switching to a pull casing plugging is acceptable.
4) For 980' plug: pump plug and displace, shut-in, WOC 4 hours and tag plug – must be 243’ or shallower.
