Abstract:
A method of enhancing a certain type of seismic event data with respect to an overall set of seismic event data which includes other, different types of seismic event data, all of said data being recorded for a particular subterranean region, said method comprising the steps of:a) generating a particular type of gather from said overall data such that the gather includes at least a portion of said certain seismic event data and at least a portion of said other data;b) incorporating into said gather a series of data discrimination lines at positions and directions which are established in said gather non-analytically in a predetermined way based, at least in part, on an approximate model of the particular subterranean region; andc) using said data discrimination lines, enhancing said certain type of seismic event data which is present in said gather with respect to the other data within the gather.
