THREE-DIMENSIONAL SEISMIC SURVEY METHODS USING A PERTURBATION PATTERN TO PROVIDE BIN FRACTIONATION

摘要

A receiver point arrangement is deployed having one or more receiver lines, each receiver line having receivers with substantially uniform inline spacing. A seismic source is triggered at each source point in an arrangement of source points along one or more source lines, each source line having source points with substantially uniform crossline spacing. A perturbation pattern is applied to at least one of the receiver point arrangement and the source point arrangement to distribute the midpoints evenly within a bin having dimensions of half of the receiver inline spacing and half the source crossline spacing across multiple locations within that bin.
