EVALUATION OF ROCK BOUNDARIES AND ACOUSTIC VELOCITIES USING DRILL BIT SOUND DURING VERTICAL DRILLING

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...
