  • Publication number: 20210148500
    Abstract: A method and fluid connection system to fluidly connect a fracturing manifold to a fracturing tree. The method includes fluidly connecting a plurality of flexible flowlines between the manifold outlet of a fracturing manifold module and the fracturing tree such that fluid from the manifold outlet is distributed into the flexible flowlines and into the fracturing tree to avoid abrupt or right angle changes in direction in all fluid connections at the fracturing tree and between the manifold outlet and the fracturing tree. The fluid connection system includes a flow distribution block having a single inlet and a plurality of outlets, and distributes fluid flow between the single inlet and the plurality of outlets without abrupt or right angle changes in direction. The flexible flowlines have a first end fluidly connected to one of the plurality of outlets, and a second end fluidly connected to the fracturing tree.

  • Patent number: 10731436
    Abstract: A ball injector for connecting below the frac head of a frac tree to accommodate and sequentially drop a ball into the axial passageway of the frac tree. The ball injector has an axial passage of an injector housing aligned with the axial passageway of the frac tree. A ball cartridge assembly stores one or more balls and sequentially delivers one ball to a port in the ball cartridge assembly. A ball launch side arm extends from the injector housing and forms a ball launch passageway communicating between the ball cartridge port and the axial passage. A first valve member in the ball launch passageway is opened to pass the ball into the axial passage, and is closed to isolate the ball cartridge assembly from a pressure in the axial passage. A second valve member between the first valve member and the ball cartridge assembly may be included to form a pressure isolation chamber between the valve members. Embodiments of ball cartridge assemblies to horizontally store a plurality of balls is provided.

  • Patent number: 10604354
    Abstract: A moving item may be treated using a treatment member. Data may be obtained that includes a width of the moving item, a maximum speed of movement for a treatment member across the moving item to provide a required level of treatment, a speed of movement of the moving item, and a length of the moving item. An extent of movement of the treatment member across the moving item in each reciprocal movement of the treatment member and a speed of reciprocal movement of the treatment member across the moving item may be calculated based at least on the data to provide a required level of treatment across the moving item. The treatment member is reciprocally moved in a required pattern across the moving item based at least on the calculated extent of movement and the calculated speed of movement to provide a full treatment coverage of the moving item.
