AquaVib™ Marine Vibrator

The SAE AquaVib™ Marine Vibrator is a towable marine source that generates seismic energy equivalent to airguns, at significantly reduced sound pressure levels, and at frequencies below the hearing range of most marine species.

The AquaVib™ subarray consists of two Triton vibrators and one lower frequency Subtone, each with different response characteristics and resonant frequencies. Advanced controller systems can enable precise acoustic output, while providing real-time feedback to ensure high levels of acoustic quality control. AquaVib™ is designed for water depths as shallow as one-meter, delivering performance and reliability in challenging transition-zones, lakes and shallow-water OBN surveys.

 

  • Bandwidth control enables overall lower signal level output.
  • Multiple-second sweep duration markedly reduces instantaneous sound pressure levels.
  • Meets updated NOAA guidelines for TTS and PTS.

OnSEIS™ Synchronized Impulsive Source Vehicles

The SAE OnSEIS™ Synchronized Impulsive Source Vehicle delivers the energy generation capabilities of larger trucks in a highly maneuverable form factor. The compact size and light weight of OnSEIS vehicles enables operation within 15 feet of most structures, while the rubber treads exert ground pressure equivalent to human footsteps to minimize environmental impact.

OnSEIS units are available with single or dual sources, increasing both acquisition design flexibility and access to challenging terrains.

Results

  • No ghosting, no harmonics
  • 15 ft. offsets
  • 10 ft. wide lines
  • 5 psi ground pressure
  • Stackable energy
  • Repeatable signature

Symphony® Broadband Seismic Acquisition

SAE’s Patent Pending technology, Symphony®, resulted from the recognition that modern field parameters were trending to tighter receiver and source spacing to improve the spatial sampling of seismic data, and as a consequence were substantially oversampling the longer wavelengths. This oversampling raises the overall cost of surveys, a situation that can be avoided by adopting a multi-grid approach. The analogy is often made with a home music system, in which the bass is projected by just one element (the woofer), but the higher frequencies are broadcast by several elements (the tweeters).

Symphony Broadband uses multiple grids of sweeps across a survey area, where the high frequencies are closely spaced, and the very low frequencies coarsely spaced, resulting in acquisition time and cost reductions compared to full broadband sweeps.
