Abstract
A determination of caprock integrity in naturally fractured reservoirs for fluid injection such as carbon capture and storage (CCS). The caprock integrity and seal integrity is determined via a fracture reactivation index (FRI). A mechanical earth model is determined to quantify the minimum principal in-situ stress in the caprock to determine the injection pressure limits and safeguard against undesired breakthrough into adjacent zones. A fracture model is generated using the mechanical earth model, and a critical stress analysis may be performed. After determination of a fracture density index and Coulomb Excessive Failure Function (CEFF), the fracture reactivation index (FRI) is determined.
