  • Publication number: 20210164313
    Abstract: A fracturing tree with valves and a junction of vertical and horizontal bores located within a shared, single block of metal is provided. In one embodiment, a system includes a hydraulic fracturing tree mounted over an onshore wellhead. The hydraulic fracturing tree includes a vertical bore and a horizontal bore that meet. A junction of the vertical bore with the horizontal bore is located in a single block of metal of the hydraulic fracturing tree. The hydraulic fracturing tree also includes a first valve positioned along the vertical bore and a second valve positioned along the horizontal bore. Both of the first and second valves can be located in the single block of metal having the junction of the vertical bore with the horizontal bore. Additional systems, devices, and methods are also disclosed.

  • Patent number: 10711556
    Abstract: A fracturing tree having fracturing fluid connections horizontally offset from a wellhead is provided. In one embodiment a system includes a fracturing tree mounted over a wellhead. The fracturing tree includes a valve to control flow of a fracturing fluid from the fracturing tree to the wellhead. The fracturing tree also includes a set of multiple goathead connections that are horizontally offset from the wellhead such that, when the fracturing fluid is received in the fracturing tree via the set of multiple goathead connections during a fracturing operation, the fracturing fluid entering the fracturing tree through the multiple goathead connections is combined at a location horizontally offset from the wellhead and is subsequently routed laterally through a shared bore toward the wellhead. Additional systems, devices, and methods are also disclosed.
