Accurate Fracture Scattering Simulation by Thin Dielectric Sheet-Based Surface Integral Equation

摘要

The thin dielectric sheet-based surface integral equation (SIE) method is introduced to the accurate simulation of fracture scattering, which is an important and challenging topic in hydrocarbon exploration. In the proposed method, the equivalent volume current is decomposed into the equivalent surface current and the constant normal current. With this decomposition, the D-field volume integral equation degenerates into the SIE, which makes our proposed method stable, accurate, and efficient at low frequency. Numerical results have demonstrated its excellent performance.
