Vertical seismic profiling (VSP) has been used over the past decade to provide seismic images near well bore. A new well bore seismic technique, the TOMEX/reg sign/ Survey, uses the natural vibrations created by the drill bit during the drilling of a well as a downhole energy source. Since the TOMEX Survey requires no downhole instrumentation, it eliminates lost rig time and avoids the complications of open-hole wireline operations. These factors are important whenever rig time is expensive or the risk associated with open-hole operations are high. Furthermore, the ease with which surface receivers can be deployed makes multioffset surveys much more cost effective than conventional offset VSP.
