08/24/2015 | 1) Submit Form 42 electronically to COGCC 48 hours prior to MIRU.
2) Comply with Rule 317.j and provide cement coverage from the end of the 7” casing to a minimum of 200' above Niobrara. Verify coverage with cement bond log.
3) Run and submit Directional Survey from TD to base of surface casing. The operator shall comply with Rule 321, and it shall be the operator’s responsibility to ensure that the wellbore complies with setback requirements in commission orders or rules prior to producing the well.

04/06/2020 | 1. Operator shall implement measures to control venting, to protect health and safety, and to ensure that vapors and odors from well operations do not constitute a nuisance or hazard to public welfare.
2. Prior to starting Bradenhead mitigation, if a sample has not been collected within the last twelve months collect Bradenhead and production gas samples for laboratory analysis. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. Copies of all final laboratory analytical results shall be provided to the COGCC within three months of collecting the samples.
3. During the first day of mitigation operator shall implement measures to get an initial estimate of the gas flow rate and/or volume from the Bradenhead. During the shut-in period record pressure data to adequately characterize the build-up. This mitigation plan may be used for six consecutive months.
4. At the conclusion of the six months, conduct a new Bradenhead test and submit the Form 17 within ten days of the test and submit a Form 4 Sundry that summarizes current well condition. The sundry should include details of the future plans and the flow rate information and pressure data.
