Abstract

The EigenRay method, recently introduced as an advanced ray-bending approach for solving two-point boundary-value ray tracing problems in three-dimensional, relatively smooth, heterogeneous, and generally anisotropic elastic media, is aimed at delivering reliable stationary ray path solutions and their dynamic characteristics in scenarios where conventional initial-value ray shooting methods become impractical. These challenging cases include simulating wave/ray propagation through complex geological structures, as well as modeling long-offset direct waves such as diving waves, head waves, and tunneling waves that propagate laterally along dominant refractors or through local anomalies. Overcoming these challenges makes the EigenRay method an attractive tool in seismic workflows for anisotropic nonlinear tomographic inversion and high-resolution imaging in moderate to complex geological settings. The approach begins with initial nonstationary ray paths, predicted through interpolation or extrapolation from conventional ray-shooting results - enabling estimates even in non-illuminated regions.
