Abstract

Example computer-implemented methods, media, and systems for evaluating density and seismic impedance values of geologic layers using drill bit sound during drilling are disclosed. One example computer-implemented method includes receiving an acoustic signal associated with a sound produced by a well tool implemented to perform a well operation by contacting a portion of a subterranean zone, where the acoustic signal includes a source acoustic signal and a reflected acoustic signal, the reflected acoustic signal is produced in response to the source acoustic signal, and the sound is produced during a drilling operation. The acoustic signal is processed to determine the source acoustic signal and the reflected acoustic signal. A first signal is determined based on the source acoustic signal. A second signal is determined based on the reflected acoustic signal. Properties of the subterranean zone are determined based on a convolution of the first signal and the second signal.
