A unit of Willbros Group Inc.'s oil and gas business has been awarded a contract by Energy Transfer Partners LP to construct a portion of the Red River Gathering Pipeline (RRG). Work is to include construction of 97 miles of 30-inch diameter pipeline from Ardmore, OK to Denton, TX. Construction is scheduled to begin in early April. The project is part of an agreement for Energy Transfer to provide gas gathering, processing and transportation services in the Woodford and Barnett shales for XTO Energy Inc., a subsidiary of ExxonMobil Corp. (see Shale Daily, Oct. 24, 2011). "The significant growth in the midstream market is driving additional opportunities for our strategy to offer comprehensive services to project developments in the liquid-rich drilling plays such as the Woodford shale," said Willbros CEO Randy Harl.
