Abstract

In a real seismic exploration, seismic impulses are generated successively at locations spaced along a centrally located, asymmetric sawtooth shot-point line which regularly crosses a median line coincident with the line of survey. Seismic waves resulting from each impulse are detected at at least a pair of detector spreads each parallel to the median line. Preferably the detected signals are summed on a cross-steered basis, such that the resulting traces associated with crossed sets of centrepoints normal to the survey line provide directional ("dip") information to better indicate a real subsurface structure. Additionally, the detected signal can be stacked on a common depth point bases (CDPS).
