Integration of Carbon Geological Storage and Geothermal Energy Development in Low-Permeability Reservoirs

Abstract:

Carbon dioxide (CO₂) has recently been considered as an alternative geothermal working fluid because of some favourable fluid dynamics and heat transfer properties compared to water. The concept, however, was initially proposed in the context of engineered geothermal systems (EGS). EGS has encountered considerable unfavourable conditions and socio-political issues. Consequently, use of the CO₂ sequestration site to recovery geothermal energy may be practical, so called CO₂-plume geothermal (CPG) system. We have performed numerical simulations to study non-isothermal multiphase flow processes of CO₂ displacing water and behaviour of a CPG system in a low-permeability reservoir. A number of numerical simulations under various geological and pressure/temperature conditions are performed. The objective of this research is to (1) investigate the heat extraction efficiency using supercritical CO₂ in comparison with water, (2) evaluate favourable and unfavourable conditions for heat extraction.
