Abstract

Summary

Time domain Finite-difference (FD) methods are preferred in 3D seismic modeling and inversion because of their efficient use of memory and ease of implementation. However, they are still expensive computationally. To increase their efficiency without decreasing accuracy is an ever-present problem. In this abstract, we derive accurate two-step explicit marching formulae with source term for large time propagation steps. We then point out for specific problems, the appropriate manner to decide the temporal numerical scheme, and the biggest suitable time step, all for getting most effective-cost numerical wave propagation.
