11/12/2020 | With next year’s sundry provide a more specific plan forward. Merely specifying that the well will be plugged or RTP before the next MIT is not sufficient.
EG. Bonanza Creek is working through a large backlog of PA work. Based on budgeting, Bonanza Creek currently plans to plug a total of AAA wells in in 2020, and BBB wells in 2021. Thus far, Bonanza Creek has plugged CCC wells in 2020 and is on track to meet our annual target. Currently, this well is planned to be plugged in YYYY.
This type of comment demonstrates that Bonanza Creek has a concrete plan forward and that said plan is being acted upon. Furthermore, this doesn't require an overly specific timeline for each well (which we understand is challenging to plan).

07/21/2022 | 1) Provide electronic Form 42 Notice of MIRU 2 business days ahead of operations and electronic Form 42 Notice of Plugging Operations 48 hours prior to mobilizing for plugging operations.
2) Prior to placing the 482’ plug: verify that all fluid migration (liquid and gas) has been eliminated. If evidence of fluid migration or pressure remains, contact COGCC Engineer for an update to plugging orders.
3) After isolation has been verified, pump surface casing shoe plug. If cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at AAA’ or shallower and provide 10 sx plug at the surface.
4) Leave at least 100’ of cement in the wellbore for each plug without mechanical isolation.

07/21/2022 | 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.
