Expansion of Geological CO2 Storage Capacity in a Closed Aquifer by Simultaneous Brine Production with CO2 Injection

Structural trapping is the primary mechanism for intensive CO2 sequestration in saline aquifers. This foundation increasing global storage; gradual switch to preferable mechanisms, such as residual saturation, dissolution, and mineral trapping, will require a long-time scale. The major constraints limiting storage capacity of structural are formation pressure structure size. Over-pressure owing injection causes disruption seal integrity indicating failure geological sequestration. other constraint on spill point determining volume. Overflowing CO2, after filling volume, migrates upward along aquifer geometry with buoyancy. study proposes methodology maximize site substructure created by an interbedded calcareous layer below point. provides various conceptual schemes, i.e., no brine production, simultaneous production pre-injection storage. By comparative analysis, location producer, rate, distance between injector producer optimized. Therefore, proposed scheme can enhance 68% beyond migration limits steering plume managing pressure.
