ENHANCED GEOTHERMAL SYSTEM GEOPRESSURIZED WITH CO2 IN DEEP SALINE AQUIFERS

Abstract

Through analytical modelling of fluid flow and geomechanical phenomena is here given birth to an energy system that integrates CCS and geothermal energy. It uses the injection of CO2 in deep saline aquifers to generate a range of pressures that facilitates the upgrade of geothermal fluids from geological formations that constitute the caprock or any porous aquifers overlaid with the aquifer reservoir. The uptake of these fluids promotes dissipate excess pressure and at the same time the settlement of primary consolidation of the formations overlying the aquifer subjected to the vertical elastic displacement. Preserves itself, in this way, the balance of the system and shows how the CCS can have a double purpose: on the one hand reduce the emission of CO2 into the atmosphere, and the other end to provide a energy contribution with the exploitation of a source of renewable energy.
