The VSI versatile seismic imager delivers sharper, more accurate images from borehole to surface. Tool efficiency is enhanced by
The modular design of the VSI imager enables flexibility in shuttle spacing on standard logging cable for acquiring three-component (3C) borehole seismic data. The small, acoustically isolated seismic sensor packages feature 3C omnitilt geophone accelerometers, with the sensors decoupled from the sonde body, for measuring the particle motion of the formation. This innovative design, along with digitization close to the sensor package, significantly reduces signal distortion by removing tool harmonic noise and tube waves from the borehole-seismic band.
The decoupled configurability of the VSI imager enables long toolstrings without acoustic degradation for obtaining high-quality multilevel seismic surveys. For positioning and correlation measurements, the VSI imager can be combined with a gamma ray tool for accurate depth control and an inclinometry tool for spatial orientation.
