ABSTRACT:
The present invention provides novel methods for identifying, characterizing and mapping seismic noise as an aid in evaluating and enhancing seismic data. In particular, an array of seismic receivers can be beam steered to sense seismic energy arriving from a plurality of azimuths. A measure of the strength of the seismic energy for each azimuth can be obtained for a plurality of arrival times, velocities and distances from the array. Displays of the azimuthal distribution of the strength of the seismic energy sensed by the areal array can then be produced for identifying and characterizing seismic noise into seismic data.
