ABSTRACT:
An apparatus and method for the exploration of hydrocarbons by obtaining a set of seismic signal traces distributed over a pre-determined three-dimensional volume of the earth and using a computer to: divide the three-dimensional volume into a plurality of vertically stacked and generally spaced apart horizontal slices; divide each of the slices into a plurality of cells having portions of at least three seismic traces located therein; measure the cross-correlation between one pair of traces lying in one vertical plane to obtain an in-line value and the cross-correlation between another pair of traces lying in another vertical plane to obtain a cross-line value; and combine the in-line value and the cross-line value to obtain one coherency value for each of the cells; and display the coherency values.
