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 asconstructed gyro survey will be submitted to COGCC with the Form 5. false 0bf83a15-aaf8-4743-bfdc-b8bd3c1b48b9 401640480 3 Drilling/Completion Operations Rule 317.p Logging Program One of the first wells drilled on the pad will be logged with Cased hole Pulsed Neutron Log with 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 in that well and have those logs attached. The Form 5 for each well shall clearly state “No open-hole logs were run” and shall reference the Rule 317.p Exception granted for the well. false 1e85489e-5b92-452c-9223-dd0d86442c64 401640480 2 Drilling/Completion Operations Crestone will comply with the “COGCC Policy for Bradenhead Monitoring During Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012. false 401640480 1ST 8 1 2 5 1 2 20 12196 1691 12196 0 0 PLANNED 401640480 CONDUCTOR 24 16 42.09 98 78 98 0 0 PLANNED 401640480 SURF 13 1 2 9 5 8 40 2281 941 2281 0 0 PLANNED 401640480 NIOBRARA NBRR 160 GWA Thread was being aborted.
