Shale environment

Given the rapidly growing oil and gas production in the Basin (Fig 1), shale production (e.g., fracking and waterflooding), PW disposal, and groundwater quality risk have become both an environmental problem and a policy issue [2,12–15]. Currently, most of the PW is deposited into nonproducing geologic intervals while a small portion gets ...
