Abstract
A method and apparatus for minimizing interference between seismic systems. The method may generally include: (a) actuating a plurality of first sources associated with a first seismic system to generate a first plurality of phase-encoded vibratory signals; (b) actuating a plurality of second sources associated with a second seismic system to generate a second plurality of phase-encoded vibratory signals that are at least partially frequency separated from the first plurality of phase-encoded vibratory signals generated in (a); and (c) detecting the first and second plurality of phase-encoded vibratory signals utilizing a first receiver positioned at a location remote from the first and second sources.
