Abstract
A role of monitoring fractures using a seismic survey has become important for geologic disposal and geological storage of carbon dioxide. Simulations are considered effective methods for obtaining knowledge about the wave propagation around a fracture. The purpose of my work was to develop a simulation program using a rotated staggered finite-difference grid with the fracture compliance matrix and to estimate its performance. Consider a horizontal fracture within a homogeneous medium and an SH wave entering it. In the case of normal incidence, I compared theoretical coefficients of reflection to calculated ones using the developed program and using a standard staggered finite-difference grid. As a result, the three showed good agreement. In conclusion, the developed program works properly and is as accurate as the standard staggered finite-difference method. In addition, this program has an advantage that velocity components are calculated on the same grid points.
