Abstract
B003 How Radar Shaped the Vibroseis Sweep P.I. Pecholcs* (Saudi Aramco) H. Hussein (Saudi Aramco) & R. Saad (Saudi Aramco) SUMMARY Attenuation of aliased and often scattered vibroseis source-generated coherent surface wave energy is one of the greatest challenges in seismic exploration on the Arabian Peninsula. To evaluate the signal-toground roll energy ratio for different vibroseis sweep designs and test the claimed benefits of in-field shaped sweep design technology (Trantham 1994) we derived a new hybrid nonlinear frequency modulated chirp signal and directly compared several full-fold nonlinear versus linear vibroseis sweep field experiments. Analysis of single-fold source records demonstrate that
