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 “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 a3daf549-5107-41d0-ad0f-9723f19a3e6a 401676697 2 Drilling/Completion Operations Operator acknowledges and will comply with COGCC policy for Bradenhead Monitoring during Hydraulic Fracturing treatments in the Greater Wattenberg Area dated May 29, 2012. false 401676697 1ST 8 1 2 5 1 2 20 16645 2259 16645 1500 0 PLANNED 401676697 CONDUCTOR 24 16 42 80 100 80 0 0 PLANNED 401676697 SURF 12 1 4 9 5 8 36 1500 400 1500 0 0 PLANNED 401676697 NIOBRARA NBRR 640 GWA Thread was being aborted.
