METHOD OF GENERATING AND CHARACTERIZING A SEISMIC SIGNAL IN A DRILL BIT

摘要

A method, apparatus and system for estimating a parameter of interest downhole is disclosed. An acoustic source signal is generated at a drill bit downhole. The generated acoustic source signal is received at a source sensor at the drill bit. A character of the generated acoustic source signal is determined from the received signal at the source sensor. The characterized source signal is used to estimate the downhole parameter of interest.
