Abstract
Implementations provide identification of rock boundaries and evaluation of rock interval velocities in subterranean zones. Actions can include receiving acoustic signals associated with sounds produced by a well tool implemented to perform a well operation by contacting a portion of a subterranean zone, the acoustic signals being composed of source acoustic signals and reflected acoustic signals produced in response to the source acoustic signals, processing the acoustic signals to determine the source acoustic signals and the reflected acoustic signals and determining properties of the subterranean zone based on the source acoustic signals and the reflected acoustic signals.
