The University of Texas at San Antonio’s Institute for Economic Development recently released an economic impact study for resource development out of the Eagle Ford shale: "'The Eagle Ford Shale has proven to be one of the most important economic engines in the state,' said Dr. Thomas Tunstall, director of the UTSA Center for Community & Business Research, and the study’s principal investigator. 'In 2011 alone, the play generated over $25 billion in revenue, supported 47,000 full-time jobs in the area, and provided $257 million in local government revenue.'"
