Borehole source of SH-waves SHock


on request
Item ID: sh-bh


The product was successfully added to basket
Main features:
  • Operating energies ‎from 1500 J
  • Operation in dry wells
  • Operations in boreholes of various diameter

The borehole source SHock is utilized to generate pressure (P-) and shear waves of horizontal polarization (SH-waves) in wells while performing the operations through crosshole seismic testing (CST) and reverse vertical seismic profiling (RVSP) methods. The energy source Jack is used as the source of energy.

The source generates a transverse wave through an asymmetric blow delivered into wall of the well. A rigid pneumo-electric line makes it easy to rotate the source in the borehole, providing generation of "right" and "left" blows. The SHock source allows excitation of seismic signal in both water-filled and dry wells, what is not feasible for borehole sparkers.

The source is supplied on a reel equipped with a high-voltage slip ring. Thus, one does not need to disconnect the energy source during operations of winding / unwinding the cable.

The set includes:
  • SHock source
  • Pneumo-electric line
  • Reel with high-voltage slip ring
  • Wire to connect a reel and a energy source
