ABSTRACT:
A power spectrum density processor is located near the drill bit while drilling. The power spectral density processor computes the power spectral density of the vibrations generated by the drill bit while drilling. The power spectral density information is telemetered to the surface where it is used to enhance drill bit seismic techniques.
