Figure 1:
The elements of a double-porosity model are: porous rock matrix
intersected by fractures. Three types of macroscopic pressure are pertinent
in such a model: external confining pressure pc, internal pressure
of the matrix pore fluid pf(1), and internal pressure of the fracture
pore fluid pf(2).

In this section, we present the fundamental governing equations
controlling the low-frequency (inertial effects being neglected) response
of a double-porosity geomechanical system.
See Berryman and Wang (1995) for details left out of the
following brief summary.
