  Fractures are ubiquitous in the subsurface. The flow and mechanical
properties of these fractures are controlled by its compliance or stiffness.
Characterizing fracture compliance and conductivity is crucial in applications
such as fault zone studies, underground CO2 sequestration, nuclear waste
repositories, geothermal energy exploitation and hydrocarbon reservoir
development. In this study, we present a time convolution solution of pressure
transient behavior of a closing fracture. From Diagnostic Fracture Injection
Tests, our presented method can be used to estimate subsurface fracture
conductivity and compliance as a function of effective stress.
