Impacts of Thermally Induced Stresses on Caprock Integrity in Depleted Hydrocarbon Reservoirs for CCS Projects

This paper presents an integrated approach for a quick look assessment of caprock integrity risks and identify a feasible operating window for CCS operations. It provides a firsthand information on caprock integrity risks based on 3D static geomechanical and wellbore-scale temperature modeling even before moving to 4D dynamic simulation modeling. The methodology established in this case study can be referred for storage projects to ensure the wellbore integrity and formation sealing integrity.
