Abstract

The invention involves providing a plurality of substantially parallel and equally spaced source lines, each of which are formed by a plurality of equally spaced seismic energy sources. A plurality of substantially parallel and equally spaced receiver lines are also provided, each formed by a plurality of equally spaced seismic energy receivers. The source and receiver lines are overlaid in a transverse crossing manner, forming a rectangular grid, so that the spacing or relative offset between source and receiver is repeated only at every second or greater number of crossings. Preferably, the relative offset is substantially zero so that a source and a receiver are substantially coincident at only every second or greater number of crossings. For each seismic disturbance, an array of common mid-point ("CMP") seismic reflections is produced.
Each CMP forms the center of one of multiple sub-bins which together form a standard bin. Stated otherwise, by slightly varying the source, receiver and line intervals so that the relative offset between a receiver and a source is repeated, but only at every second or greater crossing, the number of CMP's per bin has been multiplied. During processing of the seismic survey results, adjacent sub-bins can be incrementally combined or trimmed to adjust the standard bin to a larger or smaller size, thereby permitting an explorationist to optimize between increased fold or more detailed resolution respectively.
