  • APPARATUS AND METHOD FOR INDUCING LONGITUDINAL OSCILLATIONS IN SUBTERRANEAN DRILLING STRING
    Publication number: 20160017662
    Abstract: A cavitation apparatus (CHRS) for use in subterranean drilling with a drilling rig, the rig having a drill bit and a drilling string mounted thereto through which a drilling fluid flows to the drill bit. The cavitation apparatus (CHRS) is adapted to be mounted in-line with the drilling string through which the drilling fluid flows. The CHRS has no moving parts and produces controlled low frequency, longitudinal fluctuations of at least a portion of a drill string to enhance the drilling rate of penetration (ROP). Optionally the entire drill string can be subjected to such controlled low frequency, longitudinal fluctuations.
