Lawrence Berkeley National Laboratory, in consultation with the EPA, has developed and demonstrated new computer codes to the TOUGH+ family of codes. These two equations of state codes, RealGas and RealGasH20, allow the study of flow and transport of fluids and heat over a wide range of time frames and spatial scales in tight and shale gas reservoirs. This work will be used to test different scenarios about how gas, injection fluids or waste water related to hydraulic fracturing operations may impact drinking water resources. This work was done as part of EPA's Study of the Potential Impacts of Hydraulic Fracturing for Oil and Gas on Drinking Water Resources.You may need a PDF reader to view some of the files on this page.
