Surface Vibratory Seismic Sources

Surface Linear Vibrator (SLV) — permanent autonomous land/transition zone source.

Solar or grid-powered, crew-free autonomous vibratory seismic source engineered for permanent and frequent 4D surveys on land, swamp, lake and river.

The MicroVib™ SLV uses two vibratory motors rotating synchronized eccentric weights on a hollow steel helical anchor driven up to 100 ft into the ground — coupling the source below the near-surface attenuating layer for exceptional repeatability.

Because the anchor bypasses the low-velocity zone, the SLV delivers the repeatability that 4D reservoir work demands without the weight, cost or crew requirements of Vibroseis. Pre-scheduled autonomous sweeps run unattended controlled from any connected location.

  • Up to 11,000+ lb peak output force (@ 100Hz)
  • Customizable sweep range 0–200 Hz (model dependent)
  • Helical anchor to 100 ft below ground level and the weather-sensitive zone
  • Optional solar-powered — near zero recurring crew costs
  • Stackable in-phase for more force, or phased-array for beam-formed configuration
  • Land, swamp, lake, and river deployment options
