Engineer	Form: (02) 401485613 02/09/2018	If a Stimulation Consent Letter is not received by the COGCC for this APD prior to the stimulation of this well. For the wells listed below and any other wells belonging to another operator now within 150’ of the completed as-drilled wellbore. In a comment on the Form 5A Submit tab, operator will provide the certification of no treated interval within 150’ and will provide the following information: well name and API number, the depth of the perforation in this well nearest to the treated interval of the offset well, and the distance between the wells at that depth. 05-123-31139, 70 RANCH USX BB #35-02
Engineer	Form: (04) 401581227 03/22/2018	Revised Surface Casing setting depth from 1400', to 1500', and adjusted cement quantities proportionately.
Engineer	Form: (04) 402527022 12/01/2020	1. Operator will 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 will comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. Copies of all final laboratory analytical results will be provided to the COGCC within three months of collecting the samples. 3. Operator will 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. 4. By 2/24/2021, 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, sample analysis interpretation, and the flow rate information and pressure data.
Engineer	Form: (04) 402527022 12/01/2020	Shut in bradenhead pressure shall not exceed 50 psig.
Engineer	Form: (04) 402598503 02/24/2021	This well may be returned to annual testing and monthly monitoring. If at any point in the future well conditions meet thresholds defined by Order 1-232 a new bradenhead mitigation sundry must be filed.
Engineer	Form: (04) 402687568 05/19/2021	1. Operator will 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 will comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. Copies of all final laboratory analytical results will be provided to the COGCC within three months of collecting the samples. 3. Operator will 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 from the date test reported on the Form 17. 4. At the conclusion of the six months (9/18/2021), 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, sample analysis interpretation, and the flow rate information and pressure data. Shut in bradenhead pressure shall not exceed 50 psig.
Engineer	Form: (04) 402804934 09/24/2021	This well may be returned to annual testing and monthly monitoring. If at any point in the future bradenhead conditions meet thresholds defined by Order 1-232 a new bradenhead mitigation sundry must be filed.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Planning	Form: (02 ) 401485613 2/13/2018	Wellbore Collision Prevention- Rule 317.r Prior to drilling operations, Bonanza Creek will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed well path with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottom hole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision or harm to people or the environment.
Drilling/Completion Operations	Form: (02 ) 401485613 2/13/2018	“Rule 317.p Requirement to Log a Well One of the first wells drilled on the pad will be logged with an open-hole resistivity log with gamma-ray, from the kick-off point into the surface casing. All wells on the pad will have a cement bond log (CBL) with gamma-ray run on production casing (or on intermediate casing if production liner is run) into the surface casing. The horizontal portion of every well will be logged with a measured-while-drilling gamma-ray log. The Form 5, Completion Report, for each well on the pad will list all logs run and have those logs attached. The Form 5 for a well without open-hole logs shall clearly state “No open-hole logs were run” and shall clearly identify the type of log and the well (by API#) in which open-hole logs were run.”
Drilling/Completion Operations	Form: (02 ) 401485613 2/13/2018	Bradenhead Monitoring: Operator will comply with COGCC Policy for Bradenhead Monitoring During Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012.
Drilling/Completion Operations	Form: (02 ) 401485613 2/13/2018	Stimulation Setback – Rule 317.s Prior to completions operations, Bonanza Creek shall obtain signed written consent for any portion of the proposed wellbore’s treated interval within 150’ of an existing (producing, Shut-in, or temporarily abandoned) or permitted oil and gas well’s treated interval belonging to another operator prior to completion of the well.
