Gabor Deconvolution: Surface-Consistent and Iterative

Nonstationary deconvolution has emerged as a tool for extracting the most realistic earth reflectivity from seismic traces, because of its adaptability to the characteristics of a given data set. Recently, deconvolution using the Gabor transform has been extended to yield deconvolution operators that are not only nonstationary in time, but also surface-consistent. We describe here a further extension of the surface-consistent Gabor algorithm in which both source-receiver offset and midpoint are used to parametrize the Q-function component of the deconvolution operator, and which iteratively improves the estimates for the four components of the deconvolution operator constructed for each trace. Each iteration requires a complete re-analysis of the raw input data. We demonstrate on real data.
