Publication number: 20210189821Abstract: A latching assembly to couple a first mandrel to a second mandrel is disclosed. The latching assembly includes a plurality of wedge members disposed circumferentially and a guide plate. Each wedge member may include a semi-annular wedge body, an upper engagement lip, a lower engagement lip, and a guide pin. The guide plate may include a plurality of guide slots to translate and rotate the plurality of wedge members via the respective guide pins. Because the plurality of wedge members can be translated and rotated to lock and release the first mandrel to and from the second mandrel, the latching assembly can simplify the connection and disconnection of a first mandrel with the second mandrel.Type: ApplicationFiled: July 31, 2020Publication date: June 24, 2021Applicant: OIL STATES ENERGY SERVICES, L.L.C.Inventors: Jimmy Livingston, Bob McGuire

Patent number: 10858902Abstract: 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.Type: GrantFiled: June 24, 2020Date of Patent: December 8, 2020Assignee: OIL STATES ENERGY SERVICES, L.L.C.Inventors: Richard Brian Sizemore, Bob McGuire, Danny L.

Publication number: 20200148493Abstract: 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.Type: ApplicationFiled: March 4, 2019Publication date: May 14, 2020Applicant: OIL STATES ENERGY SERVICES, L.L.C.Inventors: Bob McGuire, Danny L.
