ABSTRACT:
A method in accordance with one embodiment of the invention includes obtaining seismic trace data for a region of interest; processing the seismic trace data to calculate at least one spectrum for at least one sample from the seismic data; calculating at least one dominant frequency (ωD) for the at least one spectrum; calculating at least one measure of energy loss at frequencies above the at least one dominant frequency (ωD) on the at least one spectrum; and locating a hydrocarbon reservoir in the region of interest using the at least one dominant frequency (ωD) and the at least one measure of energy loss.
