One of the techniques introduced in the last decade to address the improvement in productivity for vibroseis land acquisition was the cascaded sweep method (Andersen, 1995; Moerig et al., 2001). The potential to reduce the acquisition time by using this method comes from reducing the listening and system resetting time by concatenating the sweeps. In the summer of 2004 Repsol-YPF and WesternGeco conducted a field experiment in the Reynosa-Monterrey Block, Mexico, to determine if the use of the cascaded sweep method could be beneficial for the seismic exploration program planned for this block. In this article we present the results of this field experiment.
