A Sensitivity Study on Regional Pressure Buildup from Large-Scale CO2 Storage Projects

摘要: Abstract Several international researchers have in recent years evaluated the potentially far-reaching brine pressurization and migration processes resulting from storage of large volumes CO2 deep saline aquifers (e.g, ). Predictive simulations been conducted for idealized geologic systems as well sedimentary basins with promising sequestration potential. In contrast to latter studies, which often involve laterally extensive sediments capacity, we investigate here potential impact carbon a partially compartmentalized sandstone basin Southern San Joaquin Valley California, USA. The expected plume behavior injection-related pressure perturbation are modeled hypothetical project situated center basin. Uncertainty about fault is addressed by assessing two distinctive property scenarios. A systematic sensitivity study each scenario identify key parameters affecting buildup migration. We distinguish this between near-field region comprising projected size plume, where hydrogeological properties be better constrained, far-field extent buildup, parameter uncertainty can quite high.
