Descripción
highly permeable, and compliant layers or by means of suitable boundary conditions
that approximate the behavior of such thin layers. Since fracture apertures can
be very small, the numerical simulations would require the use of extremely fine
computational meshes and the use of boundary conditions would be required.
In this work, we study the validity of using boundary conditions to describe the
seismic response of fractures. For this purpose, we compare the corresponding scattering
coefficients to those obtained from a thin-layer representation. The boundary
conditions are defined in terms of fracture apertures that, in the most general case,
impose discontinuity of displacements, fluid pressures, and stresses across a fracture.
Furthermore, discontinuities of either fluid pressures, stresses, or both can be
removed, or displacement jumps proportional to the stresses and/or pressures can be
expressed via shear and normal dry compliances in order to simplify.
In the examples, we vary the permeability, thickness, and porosity of the fracture
and the type of fluid saturating the background medium and fractures. We observe
good agreement of the scattering coefficients in the seismic range obtained with the
two different approaches.
