  • Patent number: 9611727
    Abstract: An apparatus and method is provided for fracturing a well in a hydrocarbon bearing formation. The apparatus can include a valve subassembly that is assembled with sections of casing pipe to form a well casing for the well. The valve subassembly includes a sliding piston that is pinned in place to seal off ports that provide communication between the interior of the well casing and a production zone of the formation. A dart can be inserted into the well casing and propelled by pressurized fracturing fluid until the dart reaches the valve subassembly to plug off the well casing below the valve subassembly. The force of the fracturing fluid against the dart forces the piston downwards to shear off the pins and open the ports. The fracturing fluid can then exit the ports to fracture the production zone of the formation.

  • Patent number: 9476273
    Abstract: Systems and methods for activating a down hole tool in a wellbore. A trigger is moveably positioned in the interior of a base pipe and includes a first end and a second, smaller end. The trigger is moveable between an unactivated position where a port in the base pipe is blocked and an activated position where the port is open. At least one latch member prevents movement of the trigger from the unactivated position to the activated position until a predetermined force is applied to the trigger. Increasing pressure in the interior increases a force differential between the first end and the second end. When the force differential is substantially equal to the predetermined force, the latch releases and allows the trigger to move from the unactivated position to the activated position, thereby opening the port to permit activation of the down hole tool.

  • Patent number: 8978773
    Abstract: A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation.

    Abstract: A series of ball seat assemblies preferably used to open a series of sliding sleeves for formation access to a zone that is to be fractured allows sequential shifting of the sleeves with a single ball. The ball is guided by a tapered member with a lower outlet larger than the ball. The ball lands on the segments that are initially supported. Some leakage occurs between the segments but not enough to prevent pressure buildup to shift the sleeves. The tapered member closely fits to the segments to minimize leakage. Shifting the segments axially allows them to retract so the ball passes to eventually land on a non-leaking seat so that the zone can be fractured. The ball is recovered at the surface after passing the retracted segments and going through the undistorted opening in the tapered member.

That is, unlike conventional stimulation systems, embodiments herein may operate without the requirement of traditional plug-setting, perforating and fracturing interventions on a zone by zone basis for a cemented completion. Rather, the system is outfitted with frac sleeves that may be shifted open to expose the bore to the formation while simultaneously achieving a seal through a ball drop technique. Once more, this manner of operation is rendered practical by the sleeve being of a passable configuration such that cementing of the casing is not impeded.

  • Publication number: 20130220603
    Abstract: A flow tool has a sensor that detects plugs (darts, balls, etc.) passing through the tool. An actuator moves an insert in the tool once a preset number of plugs have passed through the tool. Movement of this insert reveals a catch on a sleeve in the tool. Once the next plug is deployed, the catch engages the plug on the sleeve so that fluid pressure applied against the seated plug through the tubing string can move the sleeve. Once moved, the sleeve reveals ports in the tool communicating the tool's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The actuator can use a sensor detecting passage of the plugs through the tool. A spring disposed in the tool can flex near the sensor when a plug passes through the tool, and a counter can count the number of plugs that have passed.

  • Patent number: 8505639
    Abstract: A sliding sleeve has a sensor that detects plugs (darts, balls, etc.) passing through the sleeves. A first insert on the sleeve can be hydraulically activated by the fluid pressure in the surrounding annulus once a preset number of plugs have passed through the sleeve. Movement of this first insert activates a catch on a second insert. Once the next plug is deployed, the catch engages it so that fluid pressure applied against the seated plug through the tubing string can moves the second insert. Once moved, the insert reveals port in the housing communicating the sleeve's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The first insert may also be hydraulically activated after a preset time after a plug has passed through the sleeve. Several sleeves can be used together in various arrangements to treat multiple intervals of a wellbore.

  • Publication number: 20130168098
    Abstract: An apparatus and method is provided for fracturing a well in a a hydrocarbon bearing formation. The apparatus can include a valve subassembly that is assembled with sections of casing pipe to form a well casing for the well. The valve subassembly includes a sliding piston that is pinned in place to seal off ports that provide communication between the interior of the well casing and a production zone of the formation. A dart can be inserted into the well casing and propelled by pressurized fracturing fluid until the dart reaches the valve subassembly to plug off the well casing below the valve subassembly. The force of the fracturing fluid against the dart forces the piston downwards to shear off the pins and open the ports. The fracturing fluid can then exit the ports to fracture the production zone of the formation.

  • Publication number: 20130133878
    Abstract: A circulation sub is provided that has a ball seat and a circulation port that is closed when a ball is landed on the seat. An axial passage directs the pressure surge created with the landing of the ball on the seat to the port with the actuation piston for the tool. The surge in pressure operates the actuation piston to set the tool, which is preferably a packer. In an alternative embodiment raising the circulation rate through a constriction in a circulation sub breaks a shear device and allows the restriction to shift to cover a circulation port. The pressure surge that ensues continues through the restriction to the actuating piston for the tool to set the tool.

  • Patent number: RE46793
    Abstract: Methods for preparing a wellbore casing for stimulation operations comprise the steps of cementing a wellbore casing in a wellbore, the wellbore casing having a downhole tool comprising a valve and an apparatus for restricting fluid flow through the valve, such as a ball seat, disposed above the valve. Actuation of the valve opens the valve to establish fluid communication between the wellbore casing and the formation. A plug element is disposed on a seat of the ball seat and a casing pressure test is performed. The plug element then dissolves or disintegrates over time increasing fluid communication between the wellbore casing and the formation, thereby preparing the wellbore casing for stimulation operations without additional wellbore intervention after the casing pressure test. In certain embodiments, during or after dissolution of the plug element, clean-out of the bore of the valve is performed by the plug element.
