The adaptive vibroseis technology offers a way to improve seismic survey resolution and signal-to-noise ratio. This technology employs nonlinear sweep signals that are adjusted/adapted to match the near-surface environment at each source point. The automatic adjustment of the sweep signal to match changes in source point environments along the shot line expands signal spectra and, accordingly, results in better reflection resolution, as well as in more consistent signal shapes and amplitudes along the survey line. The adjustment is introduced in real time and has virtually no effect on the progress of field surveys. Read More: http://library.seg.org/doi/abs/10.1190/segam2013-0542.1
