Full wave field simulation of flexural waves in an acoustic-viscoelastic medium

Abstract:

In this paper I present full wave field simulation results in an acoustic-viscoelastic domain and show how flexural waves interact with the surrounding air and water instead of only focusing on the flexural wave. This paper is devoted to the advantages of full wave field simulations employing viscoelastic models compared to purely elastic models. Viscoelastic simulation provides results that better resemble measured field data than equivalent elastic or 1D flexural wave simulations are capable of. Elastic full wave field simulations suffer from undesired dispersive modes and oscillations obscuring the true interaction of different wave types. Application of acoustic-viscoelastic full wave field simulation can help to test and improve planned survey geometries and the processing workflow.
