A Forward Simulation Research to Resolve the Fault Shadow Problem

Abstract

It is complicate to process the seismic data from the area below a fault, where there is the pull-up and sag phenomenon in seismic section. And geological processors are difficult to make sure whether the pull-up and sag really exist. So this phenomenon of pull-up and sag makes the fault shadow problem. This paper makes a forward simulation research deeply and presents many different geological models to execute forward numerical simulation. Many common processing flows and migration imaging methods are analyzed and used to overcome the fault shadow problem. At last, this paper concludes one fairly suitable method to resolve the fault shadow problem by comparing the different migration methods.
