Abstract
Method and apparatus for predicting surface multiples, which includes (a) selecting a target subsurface line (SSL); (b) selecting an input SSL within an aperture of the target SSL; (c) selecting a point on a line twice the distance between the input SSL and the target SSL, the point corresponding to a potential downward reflection point of the surface multiples for a trace; (d) generating a potential surface multiple for the trace corresponding to the point; (e) repeating steps (c) through (d) for each point on the line to generate an inline of potential surface multiples corresponding to each point on the line; (f) repeating steps (b) through (e) for each input SSL within the aperture of the target SSL to generate potential surface multiples for the trace corresponding to each input SSL within the aperture; and (g) adding the potential surface multiples to generate a surface multiple for the trace.
