Cutting edge Custom drill bits cut resource play development costs

摘要

Resource plays, especially in the marginally economic shale gas plays, demand an unrelenting commitment to driving down drilling and completions costs while improving production. The cutting edge of this process, the mighty drill hit, plays a crucial role. In the Eagle Ford shale, for example, a producer using a Halliburton-designed bit recently drilled an 8,595-foot well with a single bit. With an average rate of penetration of 103 feet per hour, this set the record for the fastest lateral and lowest-cost-per-foot well drilled in the Briscoe Ranch field in Maverick County, Texas, an area that typically requires three-bit runs.
