A comparison of volumetric and dynamic storage efficiency in deep saline reservoirs: An overview of IEAGHG study IEA/CON/13/208

AbstractRecently, the IEA Greenhouse Gas R&D Programme and U.S. Department of Energy commissioned the Energy & Environmental Research Center to address concerns related to the validity of volumetric techniques for estimating the CO2 storage efficiency of saline formations. Two deep saline systems were compared using volumetric and dynamic storage resource estimation methods. Results indicate that volumetric estimates are valid and nearly equivalent to dynamic results, provided that boundary conditions are properly considered and a sufficient number of injection wells and duration of injection are used. For short time frames (e.g., 50 years of injection), volumetric estimates may be optimistic
