WellStreamer is a borehole hydrophone array, specially developed for seismic acquisitions in the water-filled wells. We designed exceptionally easy to use and robust receiver array with high sensitive piezoceramic sensors for registering compressional (P) waves during VSP and cross hole surveys.

WellStreamer can be supplied in various configurations, starting from single channel and up to 48 units with typical separation of 1 m or 2 m.

Mounted on a reel with a slip ring, which can be ordered with the streamer, it provides easy to operate data acquisition solution without spending time on unplugging equipment during cable operations.
