BJ Services' save cost with ComPlete MST completion system
A completion technology that promises economic and efficiency gains over conventional multiple-trip completion and stimulation is receiving a great deal of attention, onshore and off. In numerous field trials, BJ Services' ComPlete MST (multizone, single-trip) completion system has eliminated several operational steps compared with traditional multizone frac-pack/gravel-pack completions, providing at least a 20 to 40 % reduction in completion costs and nonproductive time (NPT).
"The MST is part of BJ's ComPlete line of tools, all designed to help a client save rig time and money by minimizing the number of trips in and out of a hole," explained David Walker, Director of Completion Tools for BJ Services. "One tool replaces several different pieces of equipment, and the same ultimate goal is accomplished.
"The MST is used for single-trip perforating and gravel packing in many kinds of wells, including horizontal wells," Walker continued. "We designed the system to accomplish two purposes: to gravel-pack multiple zones and to isolate the zones such that they could be selectively produced. The tool was aimed for those reservoirs with large gross pay zones and numerous stress layers, which often present completion and stimulation challenges that single intervals do not."
