Patent number: 11332990Abstract: A downhole catcher device comprises a catching mechanism which is configured to be transferable between a first mode and a second mode. The catching mechanism is further configured for passing by a first operation element if the catching mechanism is in the first mode and for catching a second operation element if the catching mechanism is in the second mode. The transfer between the first and the second mode is triggered (or effected) by a downhole tool which is operated by the second operation element.Type: GrantFiled: December 19, 2018Date of Patent: May 17, 2022Assignee: Schoeller-Bleckmann Oilfield Equipment AGInventor: Nathan Strilchuk

Patent number: 10815754Abstract: A splitflow valve comprises a tubular body, a valve element and a lock. The tubular body defines a through hole and has at least one lateral bypass port. The valve element defines a flow restriction and is moveable along the through hole along a first direction between a first position and a second position, wherein the bypass port is closed by the valve element in the first position. In the second position the bypass port is open. The lock maintains the valve element in the second position wherein a flow of fluid entering the through hole of the tubular body is split into a first flow portion passing the flow restriction and a second flow portion exiting the at least one bypass port. Further, the lock is deactivatable to allow the valve element to return to the first position.Type: GrantFiled: August 23, 2017Date of Patent: October 27, 2020Assignee: SCHOELLER-BLECKMANN OILFIELD EQUIPMENT AGInventors: Richard Earle, Nathan Strilchuk

Patent number: 9228402Abstract: A flow control valve for use with a downhole motor includes a housing with at least one port and a sleeve with at least one opening. The sleeve is movable within the housing to align and offset the ports and openings. A first biasing member associated with a first portion of the sleeve and a second biasing member associated with a second portion of the sleeve bias the sleeve in a first direction, while pressure applied to the sleeve due to fluid flow moves the sleeve in an opposing second direction. Movement of the sleeve in the second direction compresses the first and second biasing members, disengages the first portion of the sleeve from the first biasing member, and aligns the openings with the ports to permit transmission of the pressure through the openings and ports.Type: GrantFiled: October 4, 2013Date of Patent: January 5, 2016Assignee: BICO DRILLING TOOLS, INC.Inventor: Nathan Strilchuk

Patent number: 8322461Abstract: A drilling apparatus includes an upper drill string, a lower drill string including a rotary drilling motor, an orientable rotatable connection between the drill strings, a reactive torque control device associated with the orientable rotatable connection, an orientation sensing device for providing a sensed actual orientation of the lower drill string, and a feedback control system configured to actuate the control device in response to the sensed actual orientation to achieve a target orientation of the lower drill string. A drilling method includes actuating the control device to prevent relative rotation of the drill strings, providing a sensed actual orientation of the lower drill string, comparing the sensed actual orientation with a target orientation of the lower drill string, actuating the control device to allow the lower drill string to rotate to provide the target orientation, and actuating the control device to prevent relative rotation of the drill strings.Type: GrantFiled: November 4, 2008Date of Patent: December 4, 2012Assignee: Halliburton Energy Services, Inc.Inventors: Richard T. Hay, Paul Botterell, Terence Schroter, Nathan Strilchuk
