Patent number: 11649697Abstract: An apparatus performs a method for cleaning a wellbore. The apparatus is a jet sub including an engine, a flow diverter and mixing throat. The engine propels a driving fluid at a first end of the jet sub towards a second end of the jet sub along a longitudinal axis of the jet sub. The flow diverter redirects the driving fluid by a redirection angle that is an obtuse angle. The mixing throat receives a mixed fluid including the driving fluid from the flow diverter and induced fluid drawn into the mixing throat by the driving fluid. The mixed fluid is injected into an annulus of the wellbore at the obtuse angle.Type: GrantFiled: December 21, 2020Date of Patent: May 16, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Adam Larsen, Fernando Javier Parra Ferrer, Hernando Andres Garcia Silva

Patent number: 11649687Abstract: A high expansion anti-rotation anchor catcher includes a helical track positioned on an exterior surface of a tubular body. An expandable gripper cage is provided having an axially fixed hub mounted for rotation about the tubular body and an axially movable hub mounted for rotation about the tubular body. Pivoting linkages which support outwardly oriented grippers extend between the axially fixed hub and the axially movable hub. The axially movable hub has a track follower that engages the helical track on the exterior surface of the tubular body. Rotation of the tubular body in a first rotational direction causes the track follower to move along the helical track toward the axially fixed hub, thereby placing the expandable gripper cage in compression and causing the pivoting linkages and grippers to pivot outwardly away from the tubular body to secure the anchor in position.Type: GrantFiled: March 29, 2022Date of Patent: May 16, 2023Inventor: James Dawson

Patent number: 11624235Abstract: Systems for drilling or tunneling include an assembly for accelerating a projectile into a region of geologic material. An interaction between the projectile and the geologic material extends a borehole and forms debris. The debris may be reduced in size by moving the debris to a crushing device. The reduced-size debris is then moved toward the surface using fluid movement. Water jets or other types of devices may be used to cut or deform a perimeter of a region of geologic material before the projectile is accelerated to control the shape of the borehole and the manner in which debris is broken from the geologic material.Type: GrantFiled: August 16, 2021Date of Patent: April 11, 2023Assignee: HYPERSCIENCES, INC.Inventors: Mark C. Russell, Lance D. Underwood, Tristen Cutshall

Patent number: 11608704Abstract: A joint-locking plug is deployed next to tubing joint connection gap. The actuation of the joint-locking plug allows expanding a gripping portion which includes a protrusion section. The contact between the protrusion section of the gripping portion with the inner surface of the tubing string allows to end the actuation. Due to the bi-stable slips, the pumping of an actuated plug will engage the protrusion section of the gripping portion inside the joint connection gap, and provide the locking of the gripping portion of the plug. By further applying a fluid pressure, the anchoring section of the gripping portion gets engaged and further set the plug in place, allowing to perform further operation with the plug.Type: GrantFiled: April 22, 2022Date of Patent: March 21, 2023Assignee: SOLGIX, INCInventor: Gregoire Max Jacob

Patent number: 11598169Abstract: A string guide comprising an upper mandrel, a lower muleshoe guide concentric to a lower portion of the upper mandrel, and an annular fastener internal to the lower muleshoe guide that fastens the lower muleshoe guide to the upper mandrel. When the guide encounters an obstruction (e.g., a packer bore or liner top), the weight of equipment above the lower muleshoe guide elastically deforms the annular fastener which drives the lower muleshoe guide up the upper mandrel. As the lower muleshoe guide travels up the upper mandrel, internal lugs of the muleshoe guide ride a spiral groove on the upper mandrel to rotate the lower muleshoe guide around the upper mandrel.Type: GrantFiled: December 21, 2018Date of Patent: March 7, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Daniel Luther Patterson, William Ewing
