  Fractures are ubiquitous in the subsurface. The flow and mechanical
properties of these fractures are controlled by its compliance or stiffness.
Characterizing fracture compliance is crucial in applications such as fault
zone studies, underground CO2 sequestration, nuclear waste repositories and
geothermal energy exploitation. In this study, we present a method to determine
fracture compliance by modeling fracture closure on asperities using integral
transform.
