Vertical Seismic Profiling | Open Energy Information

Vertical Seismic Profile (VSP) is a technique of seismic measurements used for high resolution seismic imaging. It can also be used for correlation with surface seismic data providing velocity information and information for processing such as deconvolution parameters. The defining characteristic of a VSP is that the detectors are in a borehole.

Vinci Technologies | GEOREC- Vertical Seismic Profile tool

VSP (Vertical Seismic Profile) is the main link between time-based surface seismic imaging and depth/based well logs. It provides a high-resolution image of the structure in the vicinity of the instrumented well. One or several seismic sources on the surface are fired and recorded by the downhole receivers (GEOREC) positioned at different depth ...
