3-D areal shot-source modeling

Abstract

Abstract.A program for 3-D modeling using areal-shot source to solve the scalar wave equation is presented, implemented and tested. The method developed here in which the wave field is advanced in time by using standard time differencing schemes utilizes a spatial numerical grid to calculate spatial derivatives by the fast Hartley transform. The Hartley transform which avoids computational redundancies in terms of the number of operations and memory requirements is more efficient and economical than its progenitor. These features are crucial when dealing with 3-D seismic data. The method can save at least a magnitude of computations. The proposed algorithm can be easily implemented in parallel architecture.
