    摘要： A jarring tool used to dislodge a stuck tubular string or bottom hole assembly within an underground wellbore. A funnel element is placed underground either within, or as part of, a tubular string. A deformable ball may be seated within the funnel element to block fluid from passing within the tubular string. Hydraulic pressure may build within the tubular string until it exceeds the pressure the ball can withstand. This will cause the ball to deform and be expelled through the funnel element. With no ball to block its flow, fluid will be rapidly released through the funnel element. The rapid release of fluid will cause a powerful jarring or jolting to the tubular string or bottom hole assembly. Deformed balls may be captured in a cartridge chamber installed within the drill string and sized to create turbulent fluid flow within the drill string.

    摘要： A jarring tool used to dislodge a stuck tubular string or bottom hole assembly within an underground wellbore. Tubular strings with which the tool may be used may be formed from drill pipe, jointed pipe, or coiled tubing. A funnel element is placed underground either within, or as part of, a tubular string. A deformable ball may be seated within the funnel element to block fluid from passing within the tubular string. Hydraulic pressure may build within the tubular string until it exceeds the pressure the ball can withstand. This will cause the ball to deform and be expelled through the funnel element. With no ball to block its flow, fluid will be rapidly released through the funnel element. The rapid release of fluid will cause a powerful jarring or jolting to the tubular string or bottom hole assembly.

    摘要： An adapter assembly for use with a wellbore tool string may include a tandem seal adapter (TSA) having a TSA body extending along an axial direction and a collar having a collar body formed in a substantially annular shape and extending in the axial direction. The collar may be provided outward from the TSA in a radial direction substantially perpendicular to the axial direction. The TSA body and the collar body may overlap in the axial direction. The collar may abut the TSA.

    摘要： Pump-through standing valves, wells including the pump-through standing valves, and methods of utilizing a pump-through standing valve to deploy a downhole device are disclosed herein. The pump-through standing valves include a valve body, a standing valve at least partially formed within the valve body, and a flow-through valve at least partially formed within the valve body. The standing valve includes a standing valve fluid conduit and a standing valve flow control device. The flow-through valve includes a flow-through valve fluid conduit and a flow-through valve flow control device. The wells include a wellbore, which extends within a subterranean formation, a wellbore tubular, which extends within the wellbore, and the pump-through standing valve, which is operatively attached to the wellbore tubular.

    摘要： A liner and a method of setting the liner. The liner includes an outer tubular member, a hydraulic actuator on an outer surface of the outer tubular member for hydraulically setting a packer of the liner, and a hydraulic channel for directing fluid through the outer tubular member and into the hydraulic actuator to set the packer. The hydraulic channel has a first port at an inner surface of the outer tubular member and a second port at the outer surface of the outer tubular member at an axial location of the hydraulic actuator. The first port is at a different axial location of the outer tubular member than the second port. A fluid is pumped through the hydraulic channel into the hydraulic actuator to set the packer.
