B005 Cascaded sweeps- a method to improve vibroseis acquisition efficiency: A field test Summary 1 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 and all 2001). In the summer of 2004 Repsol-YPF and WesternGeco performed a field experiment in the Reynosa- Monterrey block Mexico to determine if the use of cascaded sweep method could be beneficial for the seismic exploration program planned for this block. The purpose of this paper is to present the results of this field experiment. Introduction FRANCISCO
