Four-Site Case Study of Water Extraction from CO2 Storage Reservoirs
Deep saline formations (DSFs) constitute the largest potential global resource for the geological storage of carbon dioxide (CO2). While several small-scale and large-scale DSF CO2;storage projects are under way, uncertainties remain relating to the capacity and injectivity of DSFs, with particular concern relating to the management of pressure and potential displacement of formation fluids. Extraction of saline waters from storage formations is a potential method to improve reservoir storage volume, manage CO2;plume migration, reduce cap rock exposure to CO2, and/or manage storage reservoir pressure. It may also lead to the generation of a new source of water that can be treated and applied to a variety of surface uses. Furthermore, sale of the extracted water may provide cost offsets for formation water extraction that ultimately reduces the cost of CO2;storage.With funding support by IEAGHG and the U.S. Department of Energy, the Energy & Environmental Research Center conducted an international project to investigate water extraction from CO2;storage reservoirs. In the present study, a total of four CO2;storageView/Download Document
