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 b538056f-f0b8-40a3-9b47-fa25698bbcb5 402881467 1 Drilling/Completion Operations Open-Hole Logging Exception: One of the first wells drilled on the pad during the first rig occupation will be logged with cased-hole neutron log with 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 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 402881467 1ST 8 1 2 5 1 2 17 17641 2060 17641 0 PLANNED P-110 false false false 402881467 CONDUCTOR 26 16 36.94 80 175 80 0 0 PLANNED A-52A false false false 402881467 SURF 13 1 2 9 5 8 36 1850 640 1850 0 0 PLANNED J-55 false false false 402881467 NIOBRARA NBRR 407-3394 1599 T6N-R64W, 6th P.M., Sec 4: Lots 3 and 4, W1/2NE1/4, S1/2NW1/4, SW1/4, W1/2SE1/4 Sec 5: Lot 1, S1/2NE1/4, SE1/4 T7N-R64W, 6th P.M., Sec 32: E1/2 Sec 33: W1/2, W1/2E1/2 Thread was being aborted.
