Patent ID: 7072768

Claim:
A method, executed by a computer, for laterally extrapolating soil properties within a seismic coverage area, wherein the method comprises the steps of: a. collecting a soil impedance measurement for selected locations in a seismic coverage area; b. correlating the soil impedance measurement to seismic amplitude at each selected location, thereby developing an amplitude-impedance formula; c. applying the amplitude-impedance formula to seismic amplitude for the seismic coverage area to convert seismic amplitude to extrapolated soil impedance for the seismic coverage area; d. collecting a soil property measurement for selected locations in the seismic coverage area; e. correlating the soil property measurement to the extrapolated soil impedance at each selected location, thereby developing an soil property-impedance formula; and f. applying the soil property-impedance formula to the extrapolated soil impedance for the seismic coverage area to convert the extrapolated soil impedance to extrapolated soil property measurements for the seismic coverage area.
