The spatial window is defined using a limited number of trace bin locations. Output traces are produced at spaced apart centers or trace bin locations over a specified time window from this 3D seismic volume. The semblance attribute or operator of the invention is calculated from a limited number and portions of seismic traces within time and spatial windows. microseismicsĭata processing of a spatial grid of seismic signals recorded by a sensor and processed over a limited time is well known by those skilled in the art to represent an underground geologic image volume, called a three dimensional (3D) seismic volume.
