f Spatial Sampling Characteristics of Wide-Tow Marine Acquisition

Reduced cost has been a key factor in promoting the use of 3-D seismic data. Improved technology and economies of scale have both contributed to cost reductions. Perhaps the most important of these innovations has been the use of multiple sources and cables in marine acquisition for increased productivity. Indeed, the number of CMP lines acquired per boat line generally is just the product of the number of sources and the number of tables.
