  • Patent number: 9926767
    Abstract: A stress reactive valve includes a valve body disposed in a subsea safety system or other elongated components of hydrocarbon production systems. The valve body includes a frangible or breakable material such that when the subsea safety system or other elongated system undergoes a stress, such as a bending stress, the frangible valve body can react to the stress by breaking and thereby establishing fluid communication or a fluid path across the valve body. In a first or unbroken condition of the valve body, the valve body prevents fluid communication between a fluid inlet and a fluid outlet. In a second or broken condition of the valve body, fluid communication is allowed between the fluid inlet and outlet. The fluid communication can be used to actuate a device, or the fluid pressure can be used as pilot pressure to actuate a pilot operated valve system.

  • Patent number: 9546538
    Abstract: Fracking ports are initially obstructed with respective biased sleeves that have an associated release device responsive to a unique signal. The signal can be electronic or magnetic and delivered in a ball or dart that is dropped or pumped past a sensor associated with each release device. Each sensor is responsive to a unique signal. When the signal is received the release device allows the bias to shift the sleeve to open the fracture port and to let a flapper get biased onto an associated seat. The flapper and seat are preferably made from a material that eventually disappears leaving an unobstructed flow path in the passage. The method calls for repeating the process in an uphole direction until the entire zone is fractured. The flapper and seat can dissolve or otherwise disappear with well fluids, thermal effects, or added fluids to the well.

  • Patent number: 9309979
    Abstract: A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, while the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs. Additionally, while the secondary spring is engaged, hydrodynamic damping of the ball opening movement is provided.

  • Publication number: 20150101823
    Abstract: An apparatus and method for restricting fluid flow with a seat assembly. The seat is configured to go from a first position, in which it is adapted to engage a plug element, to a second position, in which the plug element passes through the seat. A second portion of the seat, and alternatively of a housing in which the seat is disposed, is formed of a disintegrable material. The second portion of the seat and housing comprising the disintegrable material are isolated from a fluid flow when engaged with the seat.

  • Publication number: 20150096762
    Abstract: A device for controlling fluid flow from a subsurface fluid reservoir into a production tubing siring includes, a tubular member defining a central bore. At least one nozzle extends through a side wall of the tubular member. A popper is moveable between an open position where fluids can flow into the central, bore through the nozzle, and a closed position where the nozzle is fluidly sealed. A circumferential external bead profile is located, on the stem and a circumferential groove is located in the nozzle for mating with the head profile of the stem and maintaining the popper in a closed position. The device can also have a shear member disposed between the stem of the popper and an inner surface of the nozzle for supporting the popper in an open position before the popper Is moved to the closed position.

  • Publication number: 20150096767
    Abstract: A multiplier sleeve has a releasable seat coupled to a dog within the slidable sleeve allows a single sized ball, dart, or plug to actuate several sliding sleeves. Upon actuation by properly sized ball the ball, slidable sleeve, seat, and dog move downward where the dog is no longer supported allowing the seat to move within the slidable sleeve to a point where the seat is no longer supported thereby releasing the ball. With the slidable sleeve moved downward the port or ports in the sliding sleeve is exposed. A staged port and piston assembly inserted into the ports maintain pressure within the tubular assembly to allow the ball to move through and actuate the targeted sliding sleeves.

  • Publication number: 20150083421
    Abstract: The present invention is a valve tool utilized for hydraulically fracturing multiple zones in an oil and gas well without perforating the cement casing. An oil/gas well completion method involves the use of a valve that is installed as part of the casing string of the well. A mandrel-less casing provides for cement flow within the casing when the valve element is in a closed position and allows for axial flow of fracturing fluid through the cement casing to fracture the formation near the valve when the sleeve is open. The invention disclosed herein is an improved valve used in this process.
