Abstract

We apply shortest-path method of seismic ray tracing to irregular tetrahedral grid, which is useful for modelling highly heterogeneous media with complex geometry of interfaces. To combine low computational complexity with satisfactory accuracy we introduce specially organized interpolation of traveltimes on the second-order grid. The algorithm is extended on multiple arrivals. Performance of the algorithm is studied in numerical experiments. © 2010, European Association of Geoscientists and Engineers.
