Reservoir Simulation Study for CO2 Sequestration in Saline Aquifers
Chawarwan Khan, Lei Ge, Victor Rudolph

Abstract
Sequestration of carbon dioxide in geological formations has been recognised as one of the most promising ways to cope with greenhouse gas emissions, and saline aquifers are one of the potential storage target. This study evaluates feasibility of CO2storage in saline aquifers under different conditions. Simulation studies are carried out based on a homogeneous aquifer model. Compositional reservoir simulator (CMG-GEM) was used to simulate 10 years of CO2 injection phase and simulate the fate of CO2 post injection from hundreds to thousands of years. Different subsets of sensitive parameters are independently investigated to understand the impact of various parameter son different trapping mechanisms. Simulation results are also compared with other published research studies to provide additional insight of factors affecting CO2sequestration process.
