Abstract

CO2 geological storage has been investigated and carried out as a strategic approach to mitigate climate change caused by drastic increase of CO2 emission to the atmosphere in the past 20 years. To offset the cost associated with sequestration, partial stored CO2 can be circulated to harvest geothermal energy from the deep reservoir, which has been demonstrated more efficient than conventional water-based method. This study aims to model CO2 sequestration and subsequent geothermal production in a heterogeneous reservoir in North Oman. CO2 injected, net storage, spatiotemporal distribution of reservoir pressure, temperature and CO2 plume, and recovered geothermal energy are assessed based on the model simulation. The findings provide a preliminary feasibility evaluation of operating CO2 sequestration and CO2-circulated geothermal recovery in similar reservoirs in North Oman and worldwide.
