Application of acoustic wave solution for the analysis of reverberation

Abstract

Finite difference method offers a versatile approach to numerical computation of synthetic seismograms for a given subsurface complex geological model. Numerical solution for the acoustic wave has been derived using the Lax-Wendroff scheme for an inhomogeneous medium and implemented for the modelling of localized areas in the offshore region. The analysis of numerical seismograms indicates that the energy radiating from a point source and remaining completely within a water layer may not cause singing, whereas the energy reflected from the deeper horizons is responsible for the singing effect on the reflections. -from Authors
