Weatherford International plc has announced the commercial release of its TruFrac® composite frac plug at the 2015 Intervention and Coiled Tubing Association (ICoTA) Conference and Exhibition in Booth 411. With a high level of reliability, the TruFrac composite frac plug maximises the efficiency of plug-and-perf completion operations by reducing time on location.
Increasing reliability and mitigating risk in plug-and-perf operations
Weatherford is the only integrated oilfield services company that manufactures its own 97% premium composite blend for TruFrac, which allows for the ability to control quality and consistency throughout the entire process of creating the plug.
“The TruFrac composite plug has been optimised to provide one of the shortest, smoothest plugs. This results in faster run in-times and reduced mill-out times due to the plugs’ limited metal content and reduced cutting size which allows a cleaner well,” said Mark Hopmann, Vice President of Completions at Weatherford. “In addition, the technology offers improved anchoring and sealing compared to traditional plugs, increasing reliability and mitigating risk in plug-and-perf operations.”
Specifications and case history
Because of its reliable sealing capability, the plug is rated for use in environments with temperatures up to 300°F (149°C) and pressures up to 10 000 psi (689 bar). They can be used in single- and multiple-zone stimulation operations in vertical, deviated, horizontal, or multilateral wells. When deployed in horizontal wells, the plug can run in hole at a speed of up to 500 ft/min (152 m/min).
The TruFrac® plug recently helped an operator in the Eagle Ford reduce mill-out time to an average of 10.5 minutes per plug from the industry average of 25 minutes per plug, which enabled the operator to accelerate the plug-and-perf operation to begin producing the well faster. To date, the company has successfully deployed more than 12 000 plugs with 99.98% reliability.
