Notice shall be given to all offset operators within one hundred fifty (150) feet prior to drilling. false 386262db-92a5-4afb-965e-30a3fbe5efa8 402795626 1 Drilling/Completion Operations Kerr-McGee acknowledges and will comply with the COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012 false ca197217-3fda-45c0-9198-4fe04c4316d4 402795626 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with open-hole resistivity log and 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 and have those logs attached. The Form 5 for a well without open-hole logs shall state ³Alternative Logging Program - No open-hole logs were run´ false 402795626 1ST 7 7 8 5 1 2 17 17436 2066 17436 0 PLANNED HPC110 false false false 402795626 CONDUCTOR 26 16 36.94 80 64 80 0 0 PLANNED J-55 false false false 402795626 SURF 13 1 2 9 5 8 36 1903 590 1903 0 0 PLANNED J-55 false false false 402795626 NIOBRARA NBRR 720 GWA Thread was being aborted.
