Patent number: 10508496Abstract: A downhole vibration tool that permits tool retrieval therethrough has an outer housing with an inner bore and a longitudinal axis, a rotating impeller that rotates within the inner bore of the outer housing, the rotating impeller defining an outer flow passage and an inner flow passage nested within the outer flow passage. The rotating impeller carries impeller vanes that are angled relative to a rotational axis and that extend into the outer flow passage such that fluid passing through the outer flow passage impinges on the impeller vanes to cause the rotating impeller to rotate. A flow restrictor having a variable flow area is positioned in the outer flow passage adjacent to the impeller vanes, and the rotation of the impeller vanes causes the flow area of the flow restrictor to periodically increase and decrease.Type: GrantFiled: December 14, 2017Date of Patent: December 17, 2019Assignee: DIRECTIONAL VIBRATION SYSTEMS INC.Inventors: David P. Kutinsky, Donald James Sheen, Darren William Sallis

Patent number: 6892830Abstract: The device contemplated provides a method for positioning the drill bit in a drilling operation to achieve small changes in hole angle or azimuth as drilling proceeds. Two different positions are available to the operator. The first is a straight ahead position where the tool essentially becomes a packed hole stabilizer assembly. The second position tilts the bit across a rotating fulcrum to give a calculated offset at the bit-formation interface. The direction that the bit offset is applied in relation to current hole direction is controlled by positioning the orienting pistons prior to each drilling cycle, through the use of current measurement-while-drilling (MWD) technology. Components of the tool comprise a MWD housing, upper steering and drive mandrel, non-rotating position housing, lower drive mandrel splined with the upper mandrel, rotating fulcrum stabilizer and drill bit.Type: GrantFiled: April 8, 2003Date of Patent: May 17, 2005Assignee: NQL Energy Services Canada Ltd.Inventors: Paul Noe, David P.

Patent number: 5248204Abstract: A mud motor bearing assembly is disclosed for an oil-lubricated downhole drill mud motor. A number of parallel sets of angular contact ball bearings are located between the mandrel and the bearing housing in a sealed, oil-filled chamber to provide all compressive thrust load bearing, extension thrust load bearing and radial load bearing capacity. Oil filled pistons at each end retard the progress of mud contamination into the inside of the chamber containing the ball bearings.Type: GrantFiled: February 14, 1992Date of Patent: September 28, 1993Assignee: Canadian Downhole Drill Systems, Inc.Inventors: Raymond S.
