ABSTRACT:
A method is provided by which the presence, if any, and location of a hydrocarbon reservoir or reservoirs adjacent to a subterranean surface can be determined based on DAD values which correspond to grid points of the surface. DAD values, specifically defined herein, relate to the change in seismic amplitude (Delta Amplitude) as divided by the Dip magnitude at each grid point. According to a preferred embodiment, colors are assigned to grid points based on the sign of the DAD values, and such assigned colors are plotted onto a depth/time contour map of the subterranean surface to result in a display which clearly indicates the location of any hydrocarbons.
