Reflection seismology internal multiple estimation

A system comprising:

• a processor;
• memory accessible by the processor;
• and
• processor-executable instructions stored in the memory that are executable to instruct the system to:
• receive seismic data of a seismic survey of a subterranean environment wherein the seismic data are acquired via survey equipment that comprises seismic energy sources and seismic energy receivers arranged according to a seismic survey geometry;
• define a two-dimensional domain in dimensions x and y;
• identify a target trace (S, R) of the seismic survey wherein S represents a source at (xS, yS) and wherein R represents a receiver at (xR, yR);
• define 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 defined with respect to a depth dimension z;
• convolve the primary traces and crosscorrelate with the generator trace for a plurality of different (X1, X2) pairs wherein each of the plurality of (X1, X2) pairs defines a line segment wherein the line segments are substantially parallel to one another;
• and
• based at least in part on the convolution of the primary traces and crosscorrelation with the generator trace, generate seismic data with attenuated multiple energy.
