  • Publication number: 20200340343
    Abstract: A frac manifold isolation tool configured to connect to a zipper spool, and comprising a mandrel that is axially movable and a hydraulic setting tool configured to move the mandrel from an open position, in which fracturing fluid is allowed to flow from a zipper spool to a connected frac tree, to a closed position, in which the mandrel and its associated cup tool prevent fracturing fluid from flowing to the connected frac tree.

  • Publication number: 20200340322
    Abstract: A well configuration unit configured to connect to a zipper manifold, and comprising a bridge connector header comprising an axial throughbore and a horizontal throughbore. A frac manifold connector is connected to the axial throughbore of the bridge connector header and comprises a mandrel that is axially movable and a hydraulic setting tool configured to move the mandrel from an open position, in which fracturing fluid is allowed to flow from the zipper manifold to a connected frac tree, to a closed position, in which the mandrel and its associated cup tool prevent fracturing fluid from flowing to the connected frac tree. A bridge connector is connected to the horizontal throughbore of the bridge connector header and comprises two bridge spools configured to connect the zipper manifold to the same frac tree.

  • Publication number: 20200277832
    Abstract: A universal atmospheric deployment device (“UADD”) for use in oil and gas production or similar applications is provided. In one embodiment, the UADD includes a number of storage carriers disposed around a pathway that can be deployed into a well bore. The figures and art described herein show that this novel feature can increase the speed and usefulness of dispatching tools down a well bore, and also decrease down time to install or retrieve these devices. This UADD also removes personnel from the hazardous area, allowing for remote deployment of tools and devices.

  • Publication number: 20200148493
    Abstract: An extendable spool is disclosed. The length of the extendable spool is able to continuously varied. The extendable spool accounts for length variances in flow lines by extending the flow line rather than redirecting the flow. Because the flow direction does not make any turns, erosion is minimized on both the extendable spool and downstream parts. The extendable spool is readily scalable from small diameters to large diameters. Because of this, it requires fewer lines and therefore less setup time to account for length differences between large diameter lines.

  • Publication number: 20200141508
    Abstract: A valve for use in oil and gas production or similar applications includes a plug or other flow barrier disposed in a cavity of a hollow valve body with a metal-to-metal sealing surface that is not reliant on any rubberized or elastomeric material to effect a seal. The figures and art described herein show that this novel feature can increase the ability of the valve to seal in high-pressure environments, and also increase the reliability of the valve when in cycling use.

  • Patent number: 10570692
    Abstract: A frac zipper manifold bridge connector comprises two bridge spools for connecting a well configuration unit of a frac zipper manifold to a frac tree of a wellhead. The connector comprises multiple connections involving threaded flanges, such that the orientation of the bridge spools may be adjusted to ensure that they are correctly aligned with the frac tree.

  • Publication number: 20180223621
    Abstract: An isolation tool and related methods for protecting a wellhead to which a casing string is operably coupled. In an exemplary embodiment, the isolation tool includes an anchor assembly adapted to be connected to the wellhead; a mandrel adapted to sealingly engage an interior portion of at least one of the wellhead and the casing string; and a lock assembly including a mandrel head connected to the mandrel and adapted to be displaced, relative to the anchor assembly and the wellhead, to sealingly engage the mandrel with the interior portion; a landing sleeve connected to the mandrel head and adapted to be displaced, relative to the mandrel head, the mandrel, the anchor assembly, and the wellhead, to engage the anchor assembly; and a connector adapted to secure the landing sleeve to the anchor assembly when the mandrel sealingly engages the interior portion and the landing sleeve engages the anchor assembly.
