Conceptual model to assess water use associated with the life cycle of unconventional oil and gas development
As the demand for energy increases in the United States, so does the demand for water used to produce many forms of that energy. Technological advances, limited access to conventional oil and gas accumulations, and the rise of oil and gas prices resulted in increased development of unconventional oil and gas (UOG) accumulations. Unconventional oil...Valder, Joshua F.; McShane, Ryan R.; Barnhart, Theodore B.; Sando, Roy; Carter, Janet M.; Lundgren, Robert F.
