Patent ID: 7987054

Claim:
A method for eliminating multiple reflections in data from a seismic survey, comprising: (a) using the seismic data, reconstructing shot gathers of data at points on an (x,y) grid, said grid being selected with dense mesh spacing sufficient to distinguish potential locations of bounce points, wherein bounce points are downward reflection points of multiple reflections; (b) selecting a reconstructed gather corresponding to a bounce point, and data trace in the survey data, then extracting two traces from the selected reconstructed gather corresponding to the source and receiver positions of the survey data trace, and convolving them, then repeating for each survey data trace within a selected aperture, thus performing pair-wise convolution of traces from a single reconstructed gather centered at a bounce-point location; (c) repeating step (b) for each remaining bounce point, and summing the convolution result for each processed trace in the survey data; and (d) predicting multiple reflections in the survey data using the results of the preceding step.
