05/15/2014 | During completion and subsequent flowback of this well, conduct concurrent monitoring of the bradenhead pressure (BHP) of the GM 321-12 (045-07778) and the GM 22-12 (045-08129) wells. COGCC noted a low top-of-cement for the GM 321-12, and has no production-string cement data for the GM 22-12. Notify COGCC if either BHP increases significantly. |

07/29/2014 | 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.

11/02/2015 | 1) The COA requiring cement coverage 200' above the top of the Mesa Verde (or Ohio Creek if present) is waived for this well. Operator is to monitor the bradenhead and notify COGCC engineering staff if the pressure exceeds 0.25 times the surface casing setting depth (TVD) in psi.
2) Operator is to perform a bradenhead test and submit the results on a Form 17 within one month of this form approval. |
