... hole at a measured depth of 17,140ft and reached TD at 19,230ft. A footage comparison to offsets drilled with fixed cutter PDC bits within a one mile radius documented the test bit performed much better than the median average ( Figure 9 ). The rolling cutter bit generated an ROP of 15ft/hr which is...
