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 will state “Open-Hole Logging Exception - No open-hole logs were run” and will clearly identify the type of log and the well (by API#) in which open-hole logs were run. false 29b3691b-2650-4f76-bb9c-5a06225ed04e 402874321 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 bd4f0388-3620-485b-bb03-c3874dc466f6 402874321 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 402874321 1ST 8 1 2 5 1 2 17 17319 2003 17319 0 PLANNED P-110 false false false 402874321 CONDUCTOR 26 16 36.94 80 175 80 0 0 PLANNED A-52A false false false 402874321 SURF 13 1 2 9 5 8 36 1850 640 1850 0 0 PLANNED J-55 false false false 402874321 NIOBRARA NBRR 407-2972 1600 T6N-R64W, 6th P.M., Section 10: E/2; Section 11: All; Section 12: W/2; Section 13: N/2NW/4; Section 14: N/2N/2; Section 15: N/2NE/4 Thread was being aborted.
