ABSTRACT:
A method of three-dimensional seismic acquisition comprising providing a plurality of substantially parallel source/receiver lines, each said source/receiver line comprising a linear array of seismic energy receivers at substantially equally spaced station intervals and a linear array of seismic energy sources located at each second station, adjacent source/receiver lines being spaced apart by two station intervals; initiating a seismic disturbance from one of said sources and receiving seismic energy at receivers disposed symmetrically about said source. Because of single direction coarse bin dimension, there is a requirement to reconstruct a uniform bin size through cooperative wavefield reconstruction in processing. The stacked common gin gathered volume of the near patch geometry of the present invention is so robust with spatially consistent, broadband signal frequencies, that accurate dealiased interpolation can be applied, e.g., by using standard F-X prediction.
