Refined over forty years of dedicated application in hard-rock characterization and forged in partnership with leaders in the nuclear waste management industry, our instruments stand as a testament to innovation and resilience. Decades of deployment in the mining sector have honed our tools into robust, reliable purveyors of high-quality seismic data, designed to excel amid the demanding conditions of active mine operations.
The large VIBSIST surface sources operate as multi-impact, time-distributed energy sources that generate wide-band, powerful seismic signals for deep high-resolution subsurface imaging. They are safe and non-destructive, specially designed for use in environmentally sensitive areas, as they do not leave any footprint on the ground. VIBSIST sources can be programmed to each generate their own unique multi-impact sequences, making them suitable for multiple-sources simultaneous acquisition at different locations of a survey.
The VIBSIST-3000 source uses a hydraulic hammer mounted on 4-wheel drive/4-wheel steering all-terrain, highly- maneuverable vehicle. High resolution probing 7—8 km deep in hard rocksand 3—4 km deep in sedimentary environments. Highly maneuverable, with outside turning radius of 3.7 m. Safe for operation from –30° to 50°C.
The VIBSIST-1000 source can probe 2—3km deep in hard rocks and 1—2 km deep in sedimentary environments. It’s outside turning radius is 2.8 m. Suitable for operation from the arctic to the desert (–30° to 50°C).
The light 500 J/impact model provides high-maneuverability and mobility in urban, industrial and mining environments. It is intended for detailed surface, borehole and underground surveys with a typical penetration range of 800 to 1000m, in reflection mode.
Intended for detailed seismic surveys in remote and environmentally sensitive areas or from tunnels and mine galleries. The light 200 J/impact model provides high-maneuverability and mobility in urban, industrial and mining environments. The VIBSIST-200 is intended for detailed surface, borehole and underground surveys with a typical penetration range of 300 to 500m, in reflection mode.
The seismic signals are generated by an electric hammer, which produces a sequence of impacts according to a pre-programmed time function. The VIBSIST-50 is intended for detailed P/S-wave and surface wave surveys with a typical penetration range up to 250 m, in reflection mode.
The VIBSIST-20S and VIBSIST-20H are portable, safe and versatile, intended for detailed P/S and surface waves surveys with a typical penetration range up to 150 m, in reflection mode. The VIBSIST-20H can be operated on vertical walls to facilitate imaging ahead and around tunnels, while the VIBSIST-20S works from surface to complete compression or shear wave surveys for geotechnical applications.
The VIBSIST-SPH64 is a coherent and reliable source for high-resolution single-hole and cross-hole seismic surveys. It transmits energy as a rapid sequence of pulses, following a monotonic time function. This borehole piezo-electric source is intended for borehole investigations as deep as 2000m and investigation range more than 150m. The frequency band is 500 – 3500Hz, which typically translates into intrinsic imaging resolution better than 1m.
This borehole mechanical hammer is designed for inverse VSP and cross-hole seismic surveys. Wideband energy, up to 1500Hz is conveyed into the ground by means of clamping wedges. The investigation range of 100 to 200 meters depends on the seismic transparency of the rock or soil. The minimum borehole diameter is 70 mm and the maximum recommended depth 200 m. The hammer is designed as motor-driven accelerated weight drop.
A cutting-edge string of borehole digital receivers, designed for precision subsurface exploration and characterization. Each of its 4-sensor levels includes a programmable 12-step gain preamplifier per channel, allowing for the full digital capture of extremely low-level signals with exceptional fidelity.
With the flexibility to incorporate a hydrophone, a low-frequency geophone, or an additional independent Z-axisgeophone as the fourth sensor, the RD-XYZH offers comprehensive subsurface imaging capabilities to depths in excess of 1600 m.
A robust and versatile string of 3-component analog geophones, engineered for advanced seismic exploration and subsurface analysis. With an adjustable gain it provides precise control over signal amplification, ensuring optimal data quality across a variety of geological settings. Capable of supporting up to 24 modules, the R-XYZ-CG can be tailored to meet the specific needs of any seismic survey, large or small. Imaging capabilities to depths of 2000 m.
A sophisticated hydrophone receiver tool, with a wide frequency response range from 1 to 28,000Hz and an intrinsic sensitivity of -193 dBV re 1μPa, ensuring detailed capture of seismic signals in diverse environments. Originally developed as a down-hole seismic receiver, the TC-32 hydrophone string is also versatile for use in shallow water and marsh areas, enhancing its application scope. The system is expandable to 96 levels in its standard configuration, and up to 600 levels with fully digital technology, making it suitable for both compact and extensive seismic surveys. Imaging capabilities to depths of 2000 m.
The PS-8R is a state-of-the-art imaging tool designed for high-resolution mapping of cracks and minor variations within rock and concrete, capable of probing up to 10 meters deep. Suitable for BQ or larger boreholes, either water-filled or dry, it operates effectively in single-hole or cross-hole modes. Its system comprises a piezoelectric borehole source and a multi-receiver probe, both featuring hydraulic clamping activated by an external pump for stable positioning. The receiver module, with eight or sixteen piezoelectric transducers spaced at 150mm intervals, offers precise data capture over a 10—100kHz frequency range.
