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. false ec889613-e891-4969-a663-8963190862b7 402881436 3 Drilling/Completion Operations Anti-collision: Prior to drilling operations, Operator 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. For the proposed well, upon conclusion of drilling operations, an as constructed gyro survey will be submitted to COGCC with the Form 5. false 28524287-8d7a-4256-9e8d-b5ea43482da7 402881436 2 Drilling/Completion Operations If a skid is performed for the subject well, then the only required BOPE tests are for the BOPE connection bonnet seal breaks, 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 30 days during the pad operations. false 402881436 1ST 8 1 2 5 1 2 17 17813 2082 17813 0 PLANNED P-110 false false false 402881436 CONDUCTOR 26 16 36.94 80 175 80 0 0 PLANNED A-52A false false false 402881436 SURF 13 1 5 9 5 8 36 1850 640 1850 0 0 PLANNED J-55 false false false 402881436 NIOBRARA NBRR 407-3392 1280 Township 7N, Range 64W, 6th P.M., Section 35: All, Section 36: All Thread was being aborted.
