Abstract
A number of authors have used the drill bit as a seismic source. In one type of study (Rector et al, 1989), an accelerometer is placed on the drill string, giving an estimate of the signature of the drill bit source. Crosscorrelating this estimate with the data recorded by one or more geophones enhances drill-bit energy in the recorded traces and gives results whose quality is comparable to VSP data.
