11/12/2014 | 1) Provide 48 hour notice prior to spud via electronic Form 42.
2) Set at least 410’of surface casing for aquifer protection. Cement to surface.
3) If production casing is set provide cement coverage to at least 200’ above the shallowest completed interval or Spergen, whichever is shallower and across Cheyenne/Dakota interval (5200’ to 4600’ min). Run and submit CBL verify cemented intervals.
4) If well is a dry hole set plugs at the following depths: 40 sks cement +/- 50’ above the Spergen, 40 sks cement across any DST w/ show, 40 sks cement 100’ below Cheyenne (5200’), 40 sks cement 50’ above top of Dakota (4600’), 50 sks cement from 50’ below surface casing shoe up into surface casing, 15 sks cement in top of surface casing, cut 4 ft below GL, weld on plate, 5 sks cement each in rat hole and mouse hole.

11/21/2014 | Open hole resistivity and gamma logs shall be run to describe the stratigraphy of the entire well bore and to adequately verify the setting depth of surface casing and aquifer coverage. On a multi-well pad, these open hole logs are only required on one of the first wells drilled on the pad and the Drilling Completion Report - Form 5 for every well on the pad shall identify which well was logged. |
