Finite difference modelling in structurally complex 3D orthorhombic medium

Pavan Kumar Elapavuluri, John C. Bancroft

Modelling seismic data is a very important aspect in exploration seismology; it is widely used in all the phases of seismic exploration. In this paper, a wave equation for a structurally complex orthorhombic medium is derived and is then used to model data over a thrust sheet model. The data generated is compared to the physical modelling data showing that the traveltimes of both physical modelling data and the numerical data match.
