Vertical seismic profile
Videos
In geophysics, vertical seismic profile is a technique of seismic measurements used for correlation with surface seismic data. The defining characteristic of a VSP is that either the energy source, or

A hydrophone is a microphone designed for underwater use, for recording or listening to underwater sound. Most hydrophones contain a piezoelectric transducer that generates an electric potential when

…which there are many types) is that either the energy source, or the detectors (or sometimes both) are in a borehole. In the most common type of VSP, hydrophones, or more often geophones or accelerometers, in the borehole record reflected seismic energy originating from a seismic source at the surface. There are…
