f A New Look at Simultaneous Sources

A fundamental factor in the cost of seismic data acquisition is the efficiency of source and receiver effort. On the receiver side, the increase in seismic channel count of recent years has resulted in increased spatial sampling and more efficient 3-D operations. Much has been done to increase source efficiency as well. Simultaneous drill and shooting operations and multiple vibrator groups are effective on land; flip-flop shooting for streamer surveys essentially doubles single-source production rates.
