Modular Digital Equipment for Borehole Seismic


Performing in onshore and offshore wells in modes: 

  • VSP
  • Offset VSP,
  • Walkaway VSP
  • 3D VSP
  • Fracking monitoring
  • Cross-well seismic tomography
  • Walkaround VSP


  • Possibility to extend the number the receivers in the string, their interchangeability
  • Can work with single-core logging cable
  • Ultra-low level of equipment self-noise (not more than 0.1 μV), enabling to record weak seismic signals and use seismic non-explosive sources of low energy; absence of industrial network interference;
  • Availability of software-controlled calibrators in the receivers, allowing to control and take into account the change of calibration characteristics of electronic measuring channels and seismic receivers in real borehole conditions;
  • Small dimensions and weight of receivers, the use of electromechanical (or magnetic) sidewall device, which ensures minimal influence of resonance "tool - borehole wall", as well as noise waves or undesirable waves (hydro-wave, cable waves) on the recorded seismic vibrations;
  • Additional depth correlation and control with the built-in gamma ray log unit
