All wells on the pad will have a cement bond log (CBL) 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 the type of log and the well (by API#) in which open-hole logs were run. false f1f64250-fa0b-460e-995c-97cdf541651f 401825383 1 Drilling/Completion Operations Prior to drilling operations, Bonanza Creek 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. false 401825383 1ST 8 1 2 5 1 2 17 12361 1953 12361 0 0 PLANNED 401825383 SURF 13 1 2 9 5 8 36 1600 743 1600 0 0 PLANNED 401825383 NIOBRARA NBRR 240 GWA Thread was being aborted.
