Abstract
Summary
The ability to simulate accurately and efficiently the propagation of seismic waves is the cornerstone of plenty of algorithms in exploration geophysics. In this paper, we propose a seismic wave propagator that can handle any form of linear elastic material such as tilted transverse isotropy or orthorhombic and deals with marine and land acquisitions indifferently. It is based on a curvilinear grid, a collocated Finite Difference scheme and a spatial filter used to remove spurious noise. The intrinsic properties of this propagator, in terms of numerical accuracy and computational efficiency, make it a relevant alternative to more elaborated but complex methods such as Spectral Elements or Discontinuous Galerkin.
