CO2 Storage Efficiency in Deep Saline Formations Stage 2 Study
The Energy & Environmental Research Center (EERC) is evaluating CO2;storage efficiency factors and how these efficiency factors may be influenced by key parameters of practical project development. Storage efficiency factors for deep saline aquifers have been previously evaluated, specifically by an IEA Greenhouse Gas R&D Programme (IEAGHG)U.S. Department of Energy (DOE) Stage 1 study, to compare static volumetric and dynamic simulation estimates of storage capacity for specific sets of reservoir locations and conditions. These methods show relatively good agreement. However, dynamic simulations indicate that it may take hundreds of years and an unrealistic number of wells to approach a static volumetrically derived estimate for an actual large-scale CO2;storage development. This study is building upon and expanding the Stage 1 study by investigating the range of storage efficiency that is achievable within a 50-year injection period for two potential storage target formations. The Minnelusa Formation of the Powder River Basin in the western United States, which was also the subject of study in the Stage 1 work, will be revisited. Also, the Bunter Sandstone of the North Sea Basin, offshore United Kingdom, will be studied.Besides the 50-year injection period, other key parameters that may influence the effectiveness of CO2;storage within that time frame are also being investigated. These include the number of wells and drilling sequence, CO2;plume management methods,View/Download Document
