COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02 ) 401810579 3/4/2019	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 ) 401810579 3/4/2019	Bonanza Creek will comply with the “COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012
Drilling/Completion Operations	Form: (02 ) 401810579 3/4/2019	Alternative Logging Program: One of the first wells drilled on the pad will be logged with Open Hole Resistivity Log and Gamma Ray Log from the kick-off point to into the surface casing. All wells on the pad will have a cement bond log 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 "Alternative Logging Program - No open-hole logs were run" and shall clearly identify (by API#, well name & number) the well in which open-hole logs were run.

Material Handling and Spill Prevention	Form: (04 ) 402703920 5/28/2021	Leak Detection Plan: Operator personnel will be on location daily conducting operations and maintenance activity at the well location and the related remote production facility to identify potential leaks in a timely manner. In addition, Operator utilizes SCADA information systems that have the ability to remotely monitor well production and activate specific valves, which can shut in production wells and stop a release at the related production location.
Material Handling and Spill Prevention	Form: (04 ) 402703920 5/28/2021	Operator constructs thrust blocks around all 90 degree riser joints to limit movement along the pipeline and further reduce the potential for a release from the pipeline.
Material Handling and Spill Prevention	Form: (04 ) 402703920 5/28/2021	Separation Equipment Containment: All produced fluids will be routed to new separation equipment. To protect shallow groundwater, Operator use separators with built-in containment. Following separation, the produced fluids will then be routed via flowline to an off-site central production facility with existing tank containment.
Material Handling and Spill Prevention	Form: (04 ) 402703920 5/28/2021	Drilling Activity Containment: Operator utilizes a portable containment liner under the drilling rig during drilling activities. This protects shallow groundwater from any potential spills surrounding the rig during drilling. A liquid release would simply be vacuumed up from the liner. When drilling activity is completed, the liner is removed and transferred to the next drilling location.
Drilling/Completion Operations	Form: (04 ) 402703920 5/28/2021	Green Completions: Test separators and associated flow lines, sand traps and emission control systems shall be installed on-site to accommodate green completions techniques. When commercial quantities of salable quality gas are achieved at each well, the gas shall be immediately directed to a sales line or shut in and conserved. If a sales line is unavailable or other conditions prevent placing the gas into a sales line, Operator shall not produce the wells without an approved variance.
