Patent number: 11278918Abstract: The present invention provides a flow insert and improved flow tube, such as a nozzle, that divides flow by generating an interrupted flow pattern, including pressure/energy gradients, in the otherwise uninterrupted flow of high pressure water through the nozzle. Cutting, cleaning, and boring performance is substantially improved. The interrupted flow pattern can provide for egress of cut or broken material to get out of the way, so cutting or cleaning action is not hampered by a continuous flow of high-pressure water. One or more balls circumferentially rotating around a ball-track assembly having a track support within the flow tube causes the flow interruption. When the flow is interrupted, the interruption's trailing edge (that is, the flow's restarting edge after the interruption) provides stronger cutting action than a continuous solid jet. The flow tube can be used for a broad array of industrial cleaning, surface preparation, cutting, and boring/drilling applications.Type: GrantFiled: June 13, 2018Date of Patent: March 22, 2022Assignees: Nozzle Dynamics, LLC, WV Jet Drilling, LLCInventor: Zachary D.

Patent number: 9567820Abstract: Apparatus and method for drilling a drain hole from a well are provided. A flexible tubing used for conveying fluid to a jet bit is confined radially by a reduced-diameter tubing piece or a liner in production tubing near the diverter used to direct the flexible tubing. Concentric tubing pieces allow location of the bit in a well by measuring weight of a work string.Type: GrantFiled: April 2, 2014Date of Patent: February 14, 2017Assignee: Buckman Jet Drilling Inc.Inventors: Zachary D. Pearl, William G. Buckman, Sr., William C. Maurer, Thomas N. Garmon

Patent number: 8267199Abstract: Apparatus and method for drilling perforations in well casing and drainholes into a subterranean formation around a well are provided. A tool body on tubing directs a mechanical cutter or jet bit to the casing. A hole is cut in casing and a rotary detent mechanism may be used to drill additional holes through casing to enable alignment of a jet bit with the holes for drilling drainholes without removing apparatus from the well. Disposable nozzles in a guide channel or nozzles on the tool body may be used for drilling through casing.Type: GrantFiled: September 20, 2011Date of Patent: September 18, 2012Assignee: Buckman Jet DrillingInventors: William G. Buckman, Sr., William C. Maurer, Zachary D. Pearl

Patent number: 8196680Abstract: A tool body on tubing directs a mechanical cutter or jet bit to the casing in an oil or gas well. A hole is cut in casing and a rotary detent mechanism may be used to drill additional holes through casing and enable alignment of a jet bit with the holes for drilling drainholes without removing apparatus from the well. Disposable nozzles in a guide channel or nozzles on the tool body may be used for drilling through casing.Type: GrantFiled: February 4, 2009Date of Patent: June 12, 2012Assignee: Buckman Jet DrillingInventors: William G.

Publication number: 20120061079Abstract: Apparatus and method for drilling drainholes into a subterranean formation around a well are provided. A tool body on tubing directs a mechanical cutter or jet bit to the casing. A hole is cut in casing and a rotary detent mechanism may be used to drill additional holes through casing and enable reliable alignment of a jet bit with the holes for drilling drainholes without removing apparatus from the well. This method significantly reduces operating time to drill multiple laterals at a given depth in a wellbore. Disposable nozzles in a guide channel or nozzles on the tool body may be used for drilling through casing.Type: ApplicationFiled: September 20, 2011Publication date: March 15, 2012Applicant: BUCKMAN JET DRILLINGInventors: William G.
