Hydrophone array

Hydrophone array WellStreamer

Main features:
  • Highly sensitive piezoceramic sensors
  • Small diameter and light weight
  • Compatibility with linear seismic recording systems


The borehole hydrophone array WellStreamer is designed for borehole seismic surveys at pressure (P) waves. The hydrophone modules utilize highly sensitive piezoceramic sensors with preamplifiers. The default number of modules on the cable is 24, but 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.
