A multi-function diverter tool is disclosed that allows positive-indication opening and closing of the tool in a downhole environment. The tool includes a first sleeve adapted to open outlet ports in the exterior surface of the tool body. The tool includes a second sleeve which is movable with respect to the first sleeve and is adapted to close the outlet ports when moved from an initial position to a second position.

Multi-function surge reduction apparatus

A method for opening a port through the wall of a ported sub including: providing a sub with a port through its tubular side wall; providing a hydraulically actuable valve to cover the port, the valve being actuable to move away from a position covering the port to thereby open the port; increasing pressure within the sub to create a pressure differential across the valve to move the valve toward the low pressure side, while the port remains closed by the valve; thereafter, reducing pressure within the sub to reduce the pressure differential; and driving the valve to move it away from a position covering the port.

Downhole sub with hydraulically actuable sleeve valve

A tubing string ported sub including a valve covering the port that can be opened by a pressure differential established across the valve. The valve includes an exposed portion that can be engaged to mechanically shift the valve.

Wellbore stimulation tool, assembly and method

A multi-function diverter tool is disclosed that allows positive-indication opening and closing of the tool in a downhole environment.

A method for opening a port through the wall of a ported sub includes providing a sub with a port through its tubular side wall and providing a hydraulically actuable valve to cover the port. The valve can be actuable to move away from a position covering the port to thereby open the port. The method also includes increasing pressure within the sub to create a pressure differential across the valve to move the valve toward the low pressure side, while the port remains closed by the valve, and thereafter, reducing pressure within the sub to reduce the pressure differential to move valve away from a position covering the port.

A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in in a pressure tight condition and later is needed to be in an open-port condition.

Sliding sleeve sub and method and apparatus for wellbore fluid treatment

A tubing string assembly is disclosed for fluid treatment of a wellbore The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off The tubing string can also be used where a ported tubing string is required to be run-m in a pressure tight condition and later is needed to be in an open-port condition A sliding sleeve in a tubular has a driver selected to be acted upon by an inner bore conveyed actuating device, the driver drives the generation of a ball stop on the sleeve.

A well tool () for use in cleaning a well of fluids and debris characterized by one or more wiper elements () for swabbing the wellbore and internal passageways () and valves () in the tool, permitting forward and reverse fluid circulation through the tool to bypass the wiper elements.

Wellbore cleanout tool

A method for opening a port through the wall of a ported sub including providing a sub with a port through its tubular side wall and providing a hydraulically actuatable valve to cover the port, the valve being actuatable to move away from a position covering the port to thereby open the port. The method further includes increasing pressure within the sub to create a pressure differential across the valve to move the valve toward the low pressure side, while the port remains closed by the valve, thereafter reducing pressure within the sub to reduce the pressure differential and driving the valve to move it away from a position covering the port.

A device for providing a seal between two tubular member in a downhole environment is presented. The sealing device provides the capability of 'boosting' or improving the seal, in the event of hydraulic pressure increases from above or below the seal.
