Checkshot survey
WebIn geophysics, vertical seismic profile ( VSP) is a technique of seismic measurements used for correlation with surface seismic data. The defining characteristic of a VSP (of 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 ... WebThe look ahead VSP survey is an option any time one wants seismic information ahead of the T.D. of a well to help locate a suspected overpressured zone, fault, amplitude …
