Drilling/Completion Operations | Form: (02 ) 402052320 5/6/2020 | Operator will perform anti-collision evaluation of all active (producing, shut-in, of temporarily abandoned) offset wellbores that have the potential of being within 150' feet of the proposed well prior to drilling operations. Notice shall be given to all offset operators prior to drilling. |
Drilling/Completion Operations | Form: (02 ) 402052320 5/6/2020 | Rule 604.c.I: Upon initial rig-up and at least once every thirty (30) days during drilling operations thereafter, pressure testing of the casing string and each component of the blowout prevention equipment including flange connections shall be performed to seventy percent (70%) of working pressure or seventy percent (70%) of the internal yield of casing, whichever is less. Pressure testing shall be conducted and the documented results shall be retained by the operator for inspection by the Director for a period of one (1) year. Activation of the pipe rams for function testing shall be
conducted on a daily basis when practicable. |
Drilling/Completion Operations | Form: (02 ) 402052320 5/6/2020 | Operator will comply with COGCC policy on bradenhead monitoring during Hydraulic Fracturing Treatment in the Greater Wattenberg Area per policy dated May 29. 2012. |
Drilling/Completion Operations | Form: (02 ) 402052320 5/6/2020 | 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 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 state “Alternative Logging Program -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. |
Emissions mitigation | Form: (04 ) 402751469 2/4/2024 | Operator will utilize best practices to maximize resource recovery and mitigate releases to protect and minimize adverse impacts to public health, safety, welfare, the environment and wildlife.
• Initial frac and drill out effluent is routed through a sand catcher/trap and a junk/sand tank to remove sand and well frac debris.
• Once any hydrocarbons are detected but prior to encountering salable quality combustible gas or significant volumes of liquid hydrocarbons (condensate or oil greater than 10 barrels per day average) the effluent is routed through a high-pressure separator and closed-top tanks to minimize emissions to the environment. Hydrocarbon liquids, produced water, and sand are separated utilizing the High-pressure separator.
• The quality (combustibility) of the gas is typically monitored directly at the High-pressure separator. When salable (combustible) quality gas is measured/detected, the gas stream is immediately diverted to the sales pipeline or the well is shut in. In the event the gas will need to be flared beyond flowback, an approved Form 4 Sundry will be obtained prior to flaring.
• The separated produced water and hydrocarbon liquids (condensate/oil) are directed to specific tanks for storage until being unloaded and hauled to disposal or sales as appropriate.
