Publication number: 20220127924Abstract: An apparatus for controlling tool face and methods of use with a torque generator connected to a drill string for drilling linear and nonlinear subterranean bore segments. In some embodiments, the apparatus and methodologies of use comprise a tool controller having an outer housing independently rotatable from and extension conduit extending therethrough and forming an annulus therebetween. The tool controller may provide for a first fluid pathway for allowing a bypass portion of fluids to flow through the torque generator, and a second fluid pathway through the annulus for allowing a torque generator portion of fluids to flow through the annulus. In some embodiments, at least one fluid flow restrictor may be provided within the annulus to controllable cause a cascading reduction in torque generator fluid pressure as it flows through the annulus, allowing high resolution tool face control over a larger (and tunable) range of drill string speed (rpm) set points.Type: ApplicationFiled: July 31, 2020Publication date: April 28, 2022Inventor: Charles Abernethy Anderson

Patent number: 10794135Abstract: An improved downhole tool for use in wellbores. In some embodiments, the tool has a first position wherein fluids entering the tool can exit via two or more flow passages, and a second position wherein some of the two or more flow passages are blocked such that fluids in the tool exit via the remaining unblocked flow passages. In other embodiments, the tool has a first position wherein fluids entering the tool are directed to some of the two or more flow passages, and a second position wherein fluids entering the tool are directed to the remaining flow passages. The tool is transitionable between the first and second positions by alternately ceasing or decreasing fluid flow to the tool and introducing or increasing fluid flow to the tool.Type: GrantFiled: April 3, 2018Date of Patent: October 6, 2020Inventor: Charles Abernethy Anderson

Patent number: 9222312Abstract: Disclosed is an apparatus for vibrating a downhole drill string operable to have a drilling fluid pumped therethrough. The apparatus comprises a tubular body securable to the drill string and having a central bore therethrough, a valve in the tubular body for venting the drilling fluid out of the drill string and a valve actuator for cyclically opening and closing the valve. The method comprises pumping a drilling fluid down the drill string and cyclically venting the drilling fluid through the valve so as to cyclically reduce the pressure of the drilling fluid in the drill string. The valve can comprise a tubular body port and a corresponding rotor port selectably alignable with the tubular body port as the rotor rotates within the central bore. The valve actuator can comprise at least one vane on the rotor for rotating the rotor as the drilling fluid flows therepast.Type: GrantFiled: June 9, 2010Date of Patent: December 29, 2015Assignee: CT Energy Ltd.Inventor: Charles Abernethy Anderson

Patent number: 6439318Abstract: A downhole drilling assembly (10) comprises a body (11) for mounting on a drillstring, the body defining a fluid conduit. A drilling fluid driven motor (12) is mounted in the body (11) and is coupled to a flow restricting device (14) axially movably mounted to the body (11). The device is coupled to a drill bit (16). In use, the flow restricting device (14) is driven by the motor (12) to vary the flow of drilling fluid through the body and produce a varying fluid pressure force to induce axial movement of the device (14) relative to the body (11), and thus provide a percussive or hammer drilling effect. The flow restricting device (14) may be coupled to the drill bit (16) by a mandrel (46) splined or otherwise coupled to the body. Alternatively, the flow restricting device (68) may be coupled to the drill bit (72) by a rotatable shaft (70), such that the motor (64) may also rotate the drill bit (72).Type: GrantFiled: June 27, 2000Date of Patent: August 27, 2002Assignee: Andergauge LimitedInventors: Alan Martyn Eddison, Charles Abernethy Anderson

Patent number: 6289596Abstract: A mounting arrangement for a pendulum in a downhole drift indicator comprises a plunger and a pendulum defining respective normally spaced apart first and second surfaces, and a pivot connection between the plunger and pendulum including a connecting pivot member. On the pivot connection being subject to a predetermined load the first and second surfaces engage to limit the load experienced by the pivot member. Also disclosed is a drift Indicator biassing arrangement, the arrangement including a housing partially defining a volume for containing a fluid reservoir, a signalling plunger and floating piston defining respective wall portions of the volume and being moveable relative to the housing. A spring acts on the piston to compress the fluid in the volume and move the signalling plunger relative to the housing.Type: GrantFiled: December 2, 1998Date of Patent: September 18, 2001Assignee: Andergauge LimitedInventors: Charles Abernethy Anderson, Alan Martyn Eddison
