Seismic modeling is an integral part of the seismic data processing for oil and gas exploration, as it provides us the seismic response for a given earth model. Grid enabled seismic wave modeling can facilitate users in the area of geophysics to calculate synthetic seismograms using federated HPC resources and complex solution algorithms without knowing their complexities. The present paper is about componentization of the wave equation based seismic modeling algorithm and its implement using Imperial College e-Science Networked Infrastructure (ICENI) Grid Middleware.
