DOEIEAGHG Study: CO2 Storage Efficiency in Deep Saline Formations Stage 2
In an effort to mitigate the increase in atmospheric concentrations of carbon dioxide (CO2) caused by emissions from large stationary sources, governmental/regulatory entities are pursuing geologic storage of CO2;as one approach in a portfolio of greenhouse gas reduction strategies. Over the past decade, various CO2;storage resource estimation methodologies have been developed for deep saline formations (DSFs, generally deeper than 800 m and with salinity greater than 10,000 mg/L), with the goal of providing reliable estimates of the potential CO2;storage in these formations. Previous work has focused on estimating the effective CO2;storage resourceresource that considers technical (geologic and engineering) constraintsto provide efficiency values for generic saline aquifers under a range of lithologies (clastics [sandstone], limestone, and dolomite [dolostone]) and an assumption of boundary conditions (i.e., open or closed hydrogeologic systems) (IEAGHG, 2009; U.S. Department of Energy, 2012; Peck and others, 2014). Recent investigations have focused on comparative analyses of volumetric (also referred to as static) and dynamic estimates of effective CO2;storage resource and efficiency (IEAGHG, 2014; Gorecki and others, 2015).
