Main features:
  • Remote spring snapping
  • Lowering the cable without load
  • Compatibility with linear seismic recording systems

The borehole seismic array with three-component clamping geophone modules GStreamer is designed for multiwave crosshole seismic testing and VSP. The number of modules on the cable can vary from 1 to 8. The interval between modules is determined by the customer.

Three normally oriented geophones with a natural frequency of 12.5 Hz are deployed in each module. The module clamping is achieved by a semi-active spring system with the possibility of remote snapping in the well. The load for the lowering the cable into borehole is not required.

The use of array with clamping modules along with borehole source of SH-waves SHock and Jack energy source allows multiwave observations with registration of SH- and P- waves at distances between wells up to 30 m.

The geophone 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.
