Summary:
Roughly half of today’s land seismic data surveys use P-wave hydraulic vibrators for sources.
The use of measured source signals and ability to control source spectral output in both
amplitude and phase has led to many innovative ways to dramatically increase acquisition
productivity. A working knowledge of how the vibrator system works and its limitations can
provide insight into how best to effectively radiate compression waves, extend bandwidth and
avoid pitfalls. This presentation offers a basic overview to help provide that insight.
