  • Publication number: 20230148442
    Abstract: A flow diverter comprises a surface to divert fluid flow within oil and gas wellbore equipment exposed to flows of abrasive, corrosive, or otherwise deleterious fluids, such as those used in hydraulic fracturing. The diverter may comprise a concave surface used to limit damage to surfaces within components used to connect a frac manifold to a frac tree or to prevent the flow of fracturing fluid from a frac manifold to a frac tree.

  • Patent number: 10858902
    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.
