GeoSonics/Vibra-Tech’s seismic reflection gives you deep insight when you need it most. Rely on us when you need to know more of what’s in store below the surface.
The seismic reflection technique is similar to the seismic refraction technique in that a sound wave is induced into the subsurface and recorded along a traverse line, resulting in depths to different reflectors. The advantage of seismic reflection over seismic refraction is that there is no assumption that velocity must increase with depth; therefore, low-velocity layers can be mapped beneath high-velocity layers, and deeper targets can be seen with greater detail at short spread lengths. Typical applications of seismic reflection surveys include depth to bedrock, depth to water table, fault location, and mapping buried stream channels and other irregular bedrock topography in more detail than the seismic refraction method.
