Combined electromagnetic and seismic acquisition system and method

摘要

Abstract A method for marine geophysical surveying according to one aspect of the invention includes towing at least one geophysical sensor streamer in a body of water. The streamer includes a plurality of spaced apart electromagnetic field receivers disposed at spaced apart locations along the streamer. The streamer also includes a plurality of seismic sensors disposed at spaced apart locations. The seismic sensors each include at least one pressure responsive receiver and at least one particle motion responsive receiver. At selected times, a seismic energy source is actuated in the water. Particle motion and pressure seismic signals, and electromagnetic field signals are detected at the respective receivers. 14 16A 16F 17 19 15 20 18A 18B 21 18A 18B 21 18A 18B 21 18C 18C 18C
