  • Patent number: 9297226
    Abstract: A system in some embodiments includes a back pressure valve configured to mount in a mineral extraction system. The back pressure valve comprises a cylindrical body comprising a venting port coaxial with a longitudinal axis of the cylindrical body and a plunger disposed in the venting port, wherein the plunger comprises a stem that extends from the venting port into an adjacent cavity of the cylindrical body. In some embodiments, a method of operating a valve, includes biasing a plunger to an open position, biasing a valve locking mechanism to a locked position in relation to a bore of a mineral extraction system, and biasing a plunger to a closed position.

  • Patent number: 8763688
    Abstract: A rubber bullet-shaped cylindrical device that functions to non-invasively plug a gushing pipe of high pressure oil. The steel belted inflatable rubber plugging device with attached high pressure hoses is inserted into a gushing oil well pipe while it pumps shipboard a high pressure stream of recycled oil itself that will not freeze at the gushing oil well to fight or knife through the oil and the pressure of the oil gushing to assist with inserting and descending the apparatus into the pipe while the operator follows a sequence of operational steps. A hose that has a vacuum applied to reduce the size of the inflatable bladder to allow it to fit it into the pipe unrestricted until it stops at the right location then recycled oil that will not freeze is pumped into the bladder to seal the oil well and to allow the cement pouring operation.

  • Patent number: 8689885
    Abstract: An isolation valve can include a pivot connecting a closure member to an actuator member which displaces when the isolation valve is actuated between open and closed configurations, whereby the pivot displaces with the actuator member. Another isolation valve can include a pivot connecting a closure member to an actuator member which displaces when the isolation valve is actuated between open and closed configurations, and a profile formed in the isolation valve. The profile biases the closure member from an open position to a closed position when the isolation valve is actuated from the open configuration to the closed configuration. A method of actuating an isolation valve includes actuating the isolation valve between open and closed configurations, and wherein actuating the isolation valve comprises simultaneously displacing an actuator member, a closure member, and a pivot which pivotably connects the closure member to the actuator member.

  • Patent number: 8430175
    Abstract: Equipment for intercepting and diverting liquid circulation flow includes three chambers and a series of valves. The chambers are equipped with a connection device with arrival or supply lines, communicating with each other, of which only a first chamber communicates with second and third chambers. Communication between the first and second chambers and between the first and third chambers each is obtained by at least two valves, one is a flow-rate valve and at least one is an equalizer valve. An upstream or downstream of each equalizer valve is coupled with a fixed or adjustable flow-blocking device. The second and third chambers do not communicate and include a three-way valve in common with each other, or include two one-way valves in counterposition. One one-way valve is open when the other is closed and vice versa, and the three-way valve or the two one-way valves are coupled with a discharge valve.

  • Publication number: 20120018174
    Abstract: An apparatus and method is provided for controlling and/or halting the uncontrolled flow of petroleum and/or natural gas from an open well head on the sea floor in which the well head is in communication with a subterranean formation. The method includes lowering a fluid control device from a drilling ship to an alignment means positioned above an open well casing through which the petroleum and/or natural gas is flowing in an uncontrolled manner, then lowering the fluid control device through and/or adjacent to the alignment means and into the open well casing until a lower section of a fluid control device enters the open well casing. The fluid control device includes an elongated member at its tip, having a diameter smaller than the inside diameter of the well head casing.

  • Patent number: 7823634
    Abstract: An isolation sleeve extends from an adapter into the bore of a tubing head to isolate high pressure frac fluid from the body of the tubing head. The isolation sleeve may be moved into and out of the bore by a hydraulic transfer piston or it may be installed and retrieved by a running tool. The isolation sleeve has a seal carrier on its lower end. The seal of the seal carrier may seal to a secondary packoff in the tubing head, on the outer diameter of the conduit, or to the rim of the conduit. The seal carrier may be movable relative to the sleeve to energize the seal.

  • Patent number: 7284602
    Abstract: A self-aligning stuffing box having a spherical joint between the upper and lower portions of the housing permits universal movement of the upper portion relative to the lower portion to permit a rod to pass through the bore if the axis of the rod is misaligned relative to the axis of the bore in each of the upper and lower housing portions. An energized seal in the upper housing resides at or below the spherical joint due to a downwardly depending central portion of the upper housing which extends into a recess formed in the lower housing permitting the height of the stuffing box to be relatively short. A second seal is positioned above the first seal and may be spaced sufficiently above the first seal to permit a flapper valve to be installed between the seals. The flapper valve is mounted through a port in the upper housing which is accessible without disassembly of the stuffing box, the seals or the wellhead.
