Topic: Impact of CO2 Sequestration on the Geomechanical Properties of a Depleted Reservoir. This topic refers to how CO2 injection into depleted oil and gas reservoirs affect the formations geomechanical properties. That is, how it affects features like faults and gthe possibility of leakages through this faults to the surface. Dissertation literature review and some part of the methodology has been done. The next phase involves simulation of CO2 injection process into a depleted reservoir to see its effect on a fault and the possibility of leakages through this faults using the Ansys Software (A simple 2D geometry), discuss details of the simulation. Discuss results of the simulation Give conclusions and proffer recommendations.
