Seismic data processing

Patent ·
OSTI ID:6592605
;

A method is described for producing a variable amplitude/phase seismic display from real seismic wiggle traces, the method comprising the steps of: selecting data points for each one of the real seismic wiggle traces, wherein the data points are equally spaced apart; determining the real amplitude for each one of the data points; determining the instantaneous phase of complex seismic wiggle traces corresponding to the real seismic wiggle traces at each one of the data points selected in; assigning color one, color two, color three or color four to each data point selected based on the instantaneous phase, determined at each data point, wherein the colors are assigned in accordance with the following wherein BA is a base angle: color one: range (BA - 90/sup 0/) to (BA - 180/sup 0/); color two: range BA to (BA - 90/sup 0/); color three: range BA to (BA + 90/sup 0/); color four: range (BA + 90/sup 0/) to (BA + 180/sup 0/); assigning a shade of color one, a shade of color two, a shade of color three or a shade of color four to each data point selected, wherein the darkness of the shade assigned is based on the amplitude determined and wherein the particular color applied to each data point is determined by the instantaneous phase; and plotting the color and shade of color assigned to each data point to produce the variable amplitude/phase seismic display.
