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.
VSP and crosshole data processing requires efficient and sophisticated processing flow. RadExPro seismic software provides all necessary algorithms for multi-component data processing – hodogram analysis, 2C/3C component orientation, wavefield separation, velocity modelling, corridor stacking and well tie to reflection seismic data. Velocity model, Quality factor and other attributes can be estimated by seismic tomography in ZondST2d and ZondST3d software. Geodevice provide processing and consultancy services.
Examples of data, acquired by GStreamer and processed in RadExPro software and ZondST2d are shown below.
