ABSTRACT:
An improved method of three-dimensional seismic acquisition of sub-surface impedance boundaries in the earth is disclosed. A rectangular grid pattern is formed from a series of substantially equally spaced and parallel source lines, each of which is formed by a plurality of equally spaced seismic energy sources, and a series of substantially equally spaced and parallel receiver lines, each of which is formed by a plurality of equally spaced seismic energy receivers. The rectangular grid is formed such that a ratio of the spacing between receiver lines and the spacing between sources yields a remainder greater than zero and a ratio of the spacing between source lines and the spacing between receivers also yields a remainder greater than zero. The source lines, receiver lines, receivers, and sources are arranged so that sources and receivers are spatially offset and so that the offset spacing between adjacent sources and receivers is only substantially repeated at every second to tenth intersection of the source and receiver lines. The sources initiate seismic disturbances which are reflected from sub-surface acoustic impedance boundaries and received by the receivers to yield seismic data.
