drill-noise vertical seismic profile — Oil & Gas Glossary

A technique using the noise of the drill bit as a source and receivers laid out along the ground to acquire a vertical seismicprofile (VSP). Acquisition and processing of a drill-noise VSP, also called a seismic-while-drilling VSP, are typically a tougher task than for more conventional VSPs. Drill-noise VSPs yield reliable time-depth information and sometimes reflection information, and can be

performed while a well is being drilled, so data from a drill-noise VSP can be considered in decisions during drilling operations.
