Estimating storage resources for geologic CO2 sequestration requires a high-level, first-cut assessment of potential reservoirs that can serve as viable storage sites.  CO2 storage resource estimates are based on physically accessible CO2 storage volume in formations without consideration of regulatory or economic constraints. These high-level resource assessments may be used for broad energy-related government policy and business decisions.  Subsurface storage volume estimates depend on geologic properties (area, thickness, and porosity of formations) and the efficiency of storage (the fraction of the accessible pore volume that is available to injected CO2). Currently there is no standard method to estimate CO2 storage potential and reported CO2 estimate widely vary.  In this work, publically available resource methodologies for predicting how much CO2 can be stored in deep saline formations are compared.  Resource methodologies applied are from the United States Department of Energy, United States Geological Survey, Carbon Sequestration Leadership Forum, Massachusetts Institute of Technology, and Lawrence Berkeley National Laboratory.  The methodologies are applied to formations throughout the United States.
