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 will 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 will 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.

9/5/2019 | Plugging
1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Properly abandon flowlines as per Rule 1105. File electronic Form 42 once abandonment complete. Within 30 days of an operator completing abandonment requirements for an off-location flowline or crude oil transfer line the operator must submit a Flowline Report, Form 44.
3) Plugs and squeezes will be placed as stated in the Plugging Procedure section of the approved NOIA unless revised by COA or prior approval from COGCC is obtained.
4) The wellbore must be static prior to placing cement plugs which are to be a minimum of 100' in length for all but surface plugs. Mechanical isolation requires a 25' cement plug, minimum.
5) Place a 50' plug (minimum) at the surface, both inside the inner most casing and in all annular spaces. Confirm cement to surface in all strings during cut and cap.
6) With the Form 6 SRA operator must provide written documentation which positively affirms each COA has been addressed.
7) Contact area inspector prior to commencing plugging operations.
8) Due to a history of bradenhead pressure as reported on the pre-plugging Form 17, wait 8 hours after pumping squeeze at 3720’, in order to assure that there is no pressure or flow before proceeding with plugging procedure, additional plugs may be neccessary to shut off pressure or flow prior to isloating the surface shoe. Contact COGCC Area Engineer to confirm plugging plans prior to continuing operations.
9) Per the mitigation plan submitted on Doc #402023153 operator will have until 12/31/19 to P&A this well.

9/5/2019 | Bradenhead Testing
Prior to starting plugging operations a bradenhead test shall be performed if there has not been a reported bradenhead test within the 60 days immediately preceding the start of plugging operations.
1) If, before opening the bradenhead valve, the beginning pressure is greater than 25 psi, sampling is required.
2) If pressure remains at the conclusion of the test, or if any liquids were present during the test, sampling is required.
The Form 17 shall be submitted within 10 days of the test. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions. If samples are collected, copies of all final laboratory analytical results shall be provided to the COGCC within three (3) months of collecting the samples.
If there is a need for sampling, contact COGCC engineering for verification of plugging procedure.

9/5/2019 | Venting
Operator shall implement measures to control unnecessary and excessive venting, to protect the health and safety of the public, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare.
