COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
Permit	Form: (02) 400406217 05/29/2013	Operator must meet water well testing requirements per Rule 318A.
Engineer	Form: (02) 400406217 05/30/2013	1)Provide notice of MIRU via an electronic Form 42. 2)Comply with Rule 317.i and provide cement coverage to a minimum of 200' above the Niobrara. Verify cement coverage with a cement bond log per 317.o.
Engineer	Form: (04) 402700179 05/26/2021	Operator shall continue to monitor pressure, and report to COGCC through annual testing. If monitored well conditions meet the thresholds defined by Order 1-232 a new bradenhead sundry must be filed.
Engineer	Form: (04) 403731373 04/05/2024	Operator shall continue to monitor pressure, and report to ECMC through annual testing. If monitored well conditions meet the thresholds defined by Order 1-232 a new bradenhead test and sundry must be filed.
Engineer	Form: (04) 403872822 09/12/2024	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 abatement, 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 ECMC within three months of collecting the samples. 3. Bradenhead gas is not to be vented to atmosphere; any gas from the Bradenhead will be routed to the specified abatement system. Operator will implement measures to get an initial estimate of the gas flow rate and/or volume from the bradenhead. The abatement program may be used for six consecutive months. 4. Operator will submit a Form 42 (“OTHER”) stating that “bradenhead abatement program has started.” 5. By 1/12/25, 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 conditions. The sundry should include details of the future plans, flow rate information, pressure data and a discussion of the sample analysis. Bradenhead pressure shall not exceed threshold pressure (50 psig).
Engineer	Form: (04) 404074544 02/18/2025	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. Bradenhead gas is not to be vented to the atmosphere; any gas from the Bradenhead will routed to to specified abatement system. Shut in bradenhead pressure shall not exceed threshold pressure . Operator will implement measures to get an estimate of the gas flow rate and/or volume from the bradenhead. 3. No later than 1/21/26, conduct a bradenhead test, submit a Form 17, and submit a Form 4 Sundry that summarizes current well condition. The well should be shut in for seven days to monitor and collect data to characterize build up pressures prior to conducting the bradenhead test. The sundry should include details of the future plans, sample analysis interpretation, bradenhead test description, and the flow rate information and pressure data. 4. If a sample has not been collected from surface casing within the last twelve months collect bradenhead 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 ECMC within three months of collecting the samples.
Engineer	Form: (04) 404558898 03/06/2026	Operator shall continue to monitor pressure and report to ECMC through annual testing. If monitored well conditions meet reaction threshold or indicate a deficiency, a new bradenhead test and sundry must be filed.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02 ) 400406217 6/24/2013	Prior to drilling operations, Operator may perform an anti-collision review of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision review may include MWD or gyro surveys and surface locations of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottomhole location. The proposed well may only be drilled if the anti-collision review results indicate that the risk of collision is sufficiently low as defined by the anti-collision plan, with separation factors greater than 1.5, or if the risk of collision has been mitigated through other means including shutting in wells, plugging wells, increased drilling fluid in the event of lost returns or as is appropriate for the specific situation. In the event of an increased risk of collision, that risk will be mitigated to prevent harm to people, the environment or property. For the proposed well, upon conclusion of drilling operations, an as-constructed directional survey will be submitted to COGCC with the Form 5. At the time of permitting, the operator has identified the following well(s) as being within close proximity of the proposed well: BELLA FEDERAL 37-7 Anti-Collision: J BURTON TUTTLE GAS UNIT #1
Drilling/Completion Operations	Form: (02 ) 400406217 6/24/2013	Kerr McGee acknowledges and will comply with the COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012.
