Effective Storage Capacity Study in a Deep Saline Aquifer within a Young Sedimentary Basin

AbstractThe thermal power plants which belong to Taiwan Power Company are major Carbon Dioxide(CO2) emitting sources in Taiwan. Thus, Taiwan Power Company launched a series of projects since 2008 to look for sites suitable for CO2 geological storage around Taiwan. After 3 years of research, Taiwan Power Company chose a deep saline aquifer sandy formation in the Taihsi basin to be the candidate site for CO2 geological storage. By this research, we established a three dimension geological model of the cap rock and reservoir rock in Taihsi basin storage site, and refer the America Department of Energy (DOE) and Japan RITE experiences to suggest an unit grid conception formula for evaluating storage capacity. Finally, we evaluated effective capacity is about 6 billion tons in the Taihsi basin site by using Geological Information System
