Fracturing can destroy top seal integrity. This section discusses two practical techniques for evaluating loss of top seal integrity resulting from strain or hydraulic fracturing. Sufficiently intense deformation in excess of top seal ductility can fracture a top seal. In addition, sufficiently high pore pressures in excess of the fracture pressure can induce natural hydraulic fracturing.
