ABSTRACT:
In seismic exploration, reflected seismic energy is detected by hydrophones to produce seismograms to emphasize a dipping formation which is of interest. The seismograms are produced by directing seismic energy from an array of sources at an angle such that it will reflect vertically from the dipping formation and intersect the hydrophones orthogonally. Directivity of the array is obtained by delaying the seismic pulses produced by each source.
