Abstract
A method of determining a rate of penetration of a drill bit using acoustic technology. The method comprises providing a drill string including a drill bit configured to drill through a subterranean formation in a wellbore and operably coupling an array of acoustic transducers to a member of the drill string. Acoustic waves are emitted toward a wall of the wellbore with at least one acoustic transducer and a frequency of the acoustic waves reflected from the wall of the wellbore are measured with at least one acoustic transducer. The array of acoustic transducers is operably coupled to a controller comprising a memory and a processor to determine a frequency shift between the emitted acoustic waves and the reflected acoustic waves. A rate of penetration of the drill bit is determined with the processor based at least in part on the frequency shift. Downhole acoustic systems for determining a rate of penetration of a drill string are also disclosed.
