Meshing for velocity modeling and ray tracing in complex velocity fields

Abstract

To minimize traveltime errors, mesh element size varies according to local velocity complexity. If velocity gradients exceed a specified threshold, we align mesh elements alongside gradient-highs, such as those occurring at sediment-salt interfaces. We may then extract interfaces used for mesh alignment as triangulated surfaces and use them to represent… (More)
