Four-site Case Study of Water Extraction from CO2 Storage Reservoirs

Abstract Water extraction is one possible means of enhancing storage capacity and managing carbon dioxide (CO 2 ) storage reservoirs. This study investigates the efficacy of water extraction in CO 2 storage applications through the use of dynamic simulations under various conditions on conceptual heterogeneous geological models based on four CO 2 storage sites in different basins of the world. The simulations indicate that the CO 2 storage capacities can be increased, and pressure and plume management can likely be accomplished through the use of water extraction.
