Fracturing manifold systems and methods

Abstract

A fracturing system is provided. In one embodiment, the fracturing system includes a fracturing manifold for routing fracturing fluid to multiple wells. The fracturing manifold can be coupled via fluid conduits to fracturing trees installed at the wells. In some cases, each fracturing tree that is coupled to the fracturing manifold is coupled by at least one rigid fluid conduit. The fracturing manifold can include a trunk line that provides fracturing fluid to multiple outlet branches, which can include valves for controlling flow of fracturing fluid to wells downstream of the valves. Additional systems, devices, and methods are also disclosed.

1 . A system comprising:
 a fracturing manifold;   a plurality of fracturing trees; and   a plurality of fluid conduits coupled between the fracturing manifold and the plurality of fracturing trees to enable receipt of fracturing fluid by the plurality of fracturing trees from the fracturing manifold, wherein each fracturing tree of the plurality of fracturing trees coupled to the fracturing manifold is coupled to the fracturing manifold by at least one rigid fluid conduit of the plurality of fluid conduits so as to provide one and only one rigid fluid pathway from the fracturing manifold to the fracturing tree, and the one and only one rigid fluid pathway is not coupled to the fracturing manifold to provide the fracturing fluid from the fracturing manifold to any other fracturing tree; and   wherein the at least one rigid fluid conduit includes a plurality of pipe joints and connection blocks coupled to one another, the plurality of pipe joints and connection blocks of the at least one rigid fluid conduit including:
 a first pipe that is attached to a first connection block via a first flanged connection; and 
 a second pipe that is in fluid communication with the first pipe and is attached to a second connection block via a second flanged connection. 
   
     
     
         2 . The system of  claim 1 , wherein the fracturing manifold includes:
 a shared trunk conduit for routing fracturing fluid to multiple fracturing trees of the plurality of fracturing trees; and   outlet branches for routing fracturing fluid from the shared trunk conduit to individual fracturing trees of the multiple fracturing trees.   
     
     
         3 . The system of  claim 2 , wherein the outlet branches of the fracturing manifold include valves to individually control flow of fracturing fluid from the shared trunk conduit to the multiple fracturing trees. 
     
     
         4 . The system of  claim 3 , wherein the outlet branches of the fracturing manifold include:
 a first outlet branch having two valves connected in series to control flow of fracturing fluid to a first fracturing tree of the multiple fracturing trees; and   a second outlet branch having two valves connected in series to control flow of fracturing fluid to a second fracturing tree of the multiple fracturing trees.   
     
     
         5 . The system of  claim 1 , wherein the at least one rigid fluid conduit is an adjustable fluid conduit that allows an operator to vary a dimension of the fluid conduit to facilitate coupling of the fluid conduit between the fracturing manifold and a fracturing tree of the plurality of fracturing trees. 
     
     
         6 . The system of  claim 1 , wherein the at least one rigid fluid conduit includes an adjustment joint that provides at least one translational degree of freedom in aligning the at least one rigid fluid conduit between the fracturing manifold and a fracturing tree of the plurality of fracturing trees. 
     
     
         7 . The system of  claim 1 , wherein the second pipe is also attached to the first connection block via an additional flanged connection. 
     
     
         8 . The system of  claim 1 , wherein the first pipe and the second pipe are connected orthogonally to one another via the first connection block. 
     
     
         9 . The system of  claim 1 , comprising a swivel along the one and only one rigid fluid pathway from the fracturing manifold to the fracturing tree.
