Abstract

Enormous amounts of carbon dioxide have been emitted into the environment in recent decades, primarily due to the fuel combustion. The rise in carbon dioxide concentration in the atmosphere is one of the basic reasons for the global changes like global warming, change in the quantity of rainfall, change in the sea levels, and the increase in the bush forest fires around the world. One of the possible solutions for reducing these global changes is to capture the excessive quantity of carbon dioxide from the atmosphere and inject it to the natural deep underground sedimentary reservoirs. During the geological storage process, carbon dioxide is pumped at greater inlet pressure, causing excess pressure building and potentially reactivating pre-existing faults in the reservoirs and caprock. The deposited carbon dioxide will flow to the top layers once the pre-existing faults are re-activated. A combined geomechanical and fault activation modeling for the Dhruma reservoir in Saudi Arabia is presented in this paper. The fault that runs through the Dhruma and Hanifa Tuwaiq strata is also taken into account during the combined geomechanical and fault activation modeling. The magnitudes of the reservoir pore pressure and ground uplift were computed during carbon dioxide injection into the reservoir. The Mohr-Coulomb failure criterion was used to assess the reservoir's stability. The magnitudes of the reservoir pore pressure and ground uplift were used to determine acceptable carbon dioxide injection variables in the present analysis.
