Abstract

The storage of CO2 in sedimentary reservoirs is one of the possible ways to alleviate the global warming caused due to the extensive emission of greenhouse gases. The concentration of CO2 in the environment is continuously increasing and if the excess amount of CO2 is not captured and stored, the concentration is expected to increase exponentially in the future. The excess CO2 in the atmosphere need to be stored in deep sedimentary reservoirs. Once CO2 is injected into the reservoir, it is mandatory to track the various associated issues like the migration of CO2 towards the caprock, the pressure buildup, ground uplift, and faults reactivation during CO2 injection. All of these issues need to be monitored to avoid the leakage of CO2 from the reservoir. In this paper, a numerical modeling study is performed to model the geomechanical behavior of the deep Qasim Reservoir in Saudi Arabia. The pore pressure buildup and ground uplift was calculated during CO2 injection into the reservoir. The reservoir stability analysis was performed using Mohr-Coulomb failure criterion.
