Technological advances have opened a new frontier in energy development-shale, the rock from which petroleum originates. Shale Energy Development is based on the author's experiences as a shale developer and describes how companies have adapted their commercial approaches to meet the challenges of shale projects. Shale Energy Development is a stand-alone sequel to Gaille's International Energy Development, which explored how companies navigate political frontiers around the globe. Both serve as texts for his courses at Rice University's Graduate School of Business and the University of Chicago Law School.
