Hydrophone array WellStreamer


on request
Item ID: h-array


The product was successfully added to basket

The borehole hydrophone array is designed for crosshole seismic testing on longitudinal (P-) waves. The hydrophone modules utilize highly sensitive piezoceramic sensors with preamplifiers. The default number of modules on the cable is 24, but per Customer's request it can vary from 1 to 48. The standard interval between pressure sensors is 1 m and the total length of the seismic array can reach 200 m or more.

The hydrophone array can be supplied on a reel with slip ring, which allows to leave the equipment plugged into it while winding and unwinding the cable.
