Permit	Form: (02 ) 402440951 9/17/2020	REJECTION: This APD has been rejected per the COGCC Rejection Process (updated May 21, 2019). 1) This APD must be a refile APD, as there are abandoned Permits on the pad, which have had API numbers assigned, and one of these API numbers must be used for this refile APD. 2) BHL location is given in an incorrect Section. 3) The mineral lease description incorrectly states the lease to be all of Sec. 28, in addition to saying "Please see attached mineral lease map". 4) The 3 check boxes addressing the Surface Owner's relationship to the minerals beneath the location are all blank, but the concomitant 2A (Doc. 402147964, Loc. ID 449806) shows them all checked. 5) The answer to "The minerals beneath this oil and gas location will be developed by this well" on the Surface & Minerals tab is 'yes', but on the concomitant 2A (Doc. 402147964, Loc. ID 449806), the answer is 'no'. 6) The spacing order number on the Spacing & Formations tab is incorrect. 7) The Submit tab lists the closest well in the same Formation as "Cottonwood Creek 4-65 28-27 4BH on the same pad", but no such well is planned, nor drilled and completed on this pad. This entire form was reviewed by permitting staff.
Permit	Form: (02 ) 402440951 10/21/2020	If conductors are preset, operator shall comply with Notice to Operators: Procedures for Preset Conductors (dated September 1, 2016, revised October 6, 2016).
Permit	Form: (02 ) 402440951 10/21/2020	Operator shall comply with Notice to Operators: Interim Reclamation Procedures for Delayed Operations (dated January 5, 2017).

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02 ) 402145822 1/23/2020	Surface casing setting depth planned a minimum of 200' below the base of the Fox Hills formation.
Drilling/Completion Operations	Form: (02 ) 402145822 1/23/2020	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 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."
Drilling/Completion Operations	Form: (02 ) 402145822 1/23/2020	If a skid is performed for the subject well, then the only required BOPE tests will be for any broken BOPE connections, as long as a full BOPE test was performed at the beginning of the pad, and as long as all necessary BOPE tests are completed at least every 21 days during the pad operations.
Drilling/Completion Operations	Form: (02 ) 402440951 10/23/2020	Prior to drilling operations, Crestone 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 wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, the Operator may have gyro surveys conducted to verify bottomhole 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. For the proposed well, upon conclusion of drilling operations, an as constructed gyro survey will be submitted to COGCC with the Form 5.
Drilling/Completion Operations	Form: (02 ) 402440951 10/23/2020	Crestone 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 ) 402440951 10/23/2020	Backup stabbing valves shall be required on well servicing operations during reverse circulation. Valves shall be pressure tested before each well servicing operation using both low-pressure air and high-pressure fluid.
Drilling/Completion Operations	Form: (02 ) 402440951 10/23/2020	Adequate blowout prevention equipment will be used on all well servicing operations.
Drilling/Completion Operations	Form: (02 ) 402440951 10/23/2020	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 will 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 will 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.
