Abstract

Tilted orthorhombic anisotropy exists in sediments with fractures that are aligned because of the presence of geological stress. Accurate seismic depth imaging requires coping with this form of anisotropy. In this paper, we investigate anisotropic raytracing in tilted orthorhombic media for quasi-P wave simulation and migration. First, we apply an acoustic approximation to the elastic wave equation to obtain the quasi-P wave dispersion equation, and then we propose a Hamiltonian function to derive the ray equations. We have implemented our orthorhombic raytracing in the wavefront reconstruction algorithm to compute traveltimes for Kirchhoff depth migration.
