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 clearly state “No open-hole logs were run” and shall clearly identify (by API#, well name & number) the well in which open-hole logs were run. false 401504546 1ST 8 1 2 5 1 2 20 20985 2839 20985 1500 0 PLANNED 401504546 CONDUCTOR 24 16 42 80 100 80 0 0 PLANNED 401504546 SURF 12 1 4 9 5 8 36 1500 400 1500 0 0 PLANNED 401504546 NIOBRARA NBRR 800 GWA Thread was being aborted.
