A stable free-surface boundary condition for two-dimensional elastic finite-difference wave simulation: SHORT NOTE
INTRODUCTION Two of the persistent problems in finite-difference solutions of the elastic wave equation are the limited stability range of the free-surface boundary condition and the boundary condition's treatment of lateral variations in velocity and density. The centered-difference approximation presented by Alterman and Karal ( 1968), for example, remains stable only for 1:1/a greater than 0...
متن کامل3d Simulation of Seismic Wave Propagation in Fractured Media Using an Integral Method Accommodating Irregular Geometries
Fractures play an important role in most carbonate and unconventional reservoirs. Precise identification of fractures and their associated properties from seismic data have significant impact on reservoir management and hydrocarbon recovery. Traditional seismic methods for fracture identification and characterization, such as shear birefringence and amplitude variations with offset and azimuth,...
متن کاملMPI- and CUDA- implementations of modal finite difference method for P-SV wave propagation modeling
Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...
متن کاملThree-dimensional anisotropic seismic wave modelling in spherical coordinates by a collocated-grid finite-difference method
S U M M A R Y To simulate seismic wave propagation in the spherical Earth, the Earth’s curvature has to be taken into account. This can be done by solving the seismic wave equation in spherical coordinates by numerical methods. In this paper, we use an optimized, collocated-grid finitedifference scheme to solve the anisotropic velocity–stress equation in spherical coordinates. To increase the e...
