Abstract
The invention is a system for conducting a geophysical survey in a wellbore, comprising a battery-powered, self-contained borehole seismic receiver which internally digitizes and records an electrical signal generated by a transducer in the receiver, and a surface control unit which records the acoustic signature of the seismic energy source deployed at the earth's surface, controls the firing of the seismic source, and correlates the recording in the receiver to the recording of the source to determine the travel time of the seismic energy through the earth.
