Abstract
A method includes receiving seismic data of a seismic survey; defining a two-dimensional domain in dimensions x and y; identifying a target trace (S, R) of the seismic survey where S represents a source at (xs, ys) and where R represents a receiver at (XR, yR); defining with respect to the two-dimensional domain, a source trace (S, X1) as a primary trace, a receiver trace (R, X2) as a primary trace, and a generator trace (X1, X2) as associated with an interbed multiple generator; convolving the primary traces and crosscorrelating with the generator trace for a plurality of different (X1, X2) pairs where each of the plurality of (X1, X2) pairs defines a line segment where the line segments are substantially parallel to one another; and, based at least in part on the convolving the primary traces and crosscorrelating with the generator trace, generating seismic data with attenuated multiple energy.
