ABSTRACT:
Apparatus for seismic surveying a borehole by simultaneously measuring seismic signals at a plurality of elevations within the borehole. A resilient tubular member is filled with a liquid and the length of the tubular member is divided into several adjacent series arranged chambers. A sensor for receiving the seismic signal is placed within each chamber, and means are provided for measuring and storing the signal received by each of the sensors. The sensors are suspended within the tubular member by a stress member, and the stress member is suspended from a bulkhead which divides the adjacent chambers, and which isolates the chambers one from the other. This arrangement of parts provides a unique structure which enables geologizing a borehole seismically in a new and unobvious manner.
