Seismic image enhancement

摘要

A method can include accessing seismic data; providing a wave function that defines, at least in part, a correlation window length; generating local autocorrelation functions for the seismic data using the correlation window length; performing cross-correlations between the wave function and each of the local autocorrelation functions to provide local cross-correlation coefficient values; determining second derivatives of the local cross-correlation coefficient values to provide local second derivative values; and rendering the local second derivative values to a display. Various other apparatuses, systems, methods, etc., are also disclosed.
