8/29/2018 | Operator acknowledges the proximity of the listed wells. Operator assures that this offset list will be remediated per the DJ Basin Horizontal Offset Policy (option 4). Operator will submit a Form 42 (“OTHER – AS SPECIFIED BY PERMIT CONDITION”) stating that appropriate mitigation will be completed, during the hydraulic stimulation of this permitted well. This Form 42 shall be filed 48 hours prior to stimulation. Operator will assure that the offset well’s Bradenhead is open and monitored during the entire stimulation treatment – a person will monitor for any evidence of fluid, a Bradenhead test will be performed prior to the beginning of stimulation. In addition, internal formation isolation is to be provided via either bridge plug or 100’ cement plug within 100’ of the top of the Niobrara.

2/21/2019 | Operator shall investigate the cause of the bradenhead pressure and spike. A Sundry must be submitted no later than March 21, 2019, that summarizes the investigation and identify the cause of the bradenhead pressure spike. If pressure is greater than 50 psi for the post-production Bradenhead Test contact COGCC Engineering with mitigation plan. |

7/3/2019 | 1) Any gas produced from the Bradenhead will be controlled with the best available technology to protect health and safety. Operator will ensure that any emissions do not constitute a nuisance or hazard to public welfare and are subject to CDPHE regulations.
2) Operator intends to blow down surface casing to 0 psi and shut in. Pressure will be allowed to build to 50 psi or for 48 hrs. Repeat cycle. During the blow down and build up cycles, the pressure and rate will be recorded in such a way as to characterize the well performance for comparison over time.
3) Commencing with the submission of this sundry, Operator intends to perform up to 12 weeks of blow down and build up cycles to be followed by a summary of well performance submitted via sundry to the COGCC at which time the future course of action will be considered.
