Fracturing system with flexible conduit
A fracturing fluid delivery system is provided. In one embodiment, the system includes a fracturing manifold and a fracturing tree. A fluid conduit is coupled between the fracturing manifold and the fracturing tree to enable receipt of fracturing fluid by the fracturing tree from the fracturing manifold through the fluid conduit. The fluid conduit includes rigid and flexible pipe segments coupled together so as to collectively provide a fluid connection from the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.
1. A method comprising:
coupling a fluid conduit having an outer body and a liner inside the outer body to one of a fracturing manifold or a fracturing tree;
bending the outer body and the liner at a flexible portion of the fluid conduit to facilitate alignment of the fluid conduit between the fracturing manifold and the fracturing tree;
coupling the fluid conduit to the other of the fracturing manifold or the fracturing tree, wherein the fluid conduit completes a fluid connection between the fracturing manifold and the fracturing tree so that fracturing fluid can be routed between the fracturing manifold and the fracturing tree through the fluid conduit;
disconnecting the fluid conduit from the fracturing tree and from the fracturing manifold;
removing the liner from the outer body of the fluid conduit;
installing a replacement liner in the outer body in place of the removed liner; and

7. The method of claim 6 , wherein operating the valve to control flow of the fracturing fluid from the fracturing manifold to the fracturing tree through the fluid conduit includes operating a valve mounted on a skid of the fracturing manifold to control flow of the fracturing fluid from the fracturing manifold to the fracturing tree.
8. The method of claim 1 , wherein coupling the fluid conduit having the outer body and the liner inside the outer body to one of the fracturing manifold or the fracturing tree includes coupling a fluid conduit including at least one of a polymer or composite material to the one of the fracturing manifold or the fracturing tree.
9. The method of claim 1 , wherein removing the liner from the outer body of the fluid conduit includes removing a corrugated liner from the outer body of the fluid conduit.
10. The method of claim 1 , wherein removing the liner from the outer body of the fluid conduit includes removing a mesh liner from the outer body of the fluid conduit.
11. A method comprising:
coupling a fluid conduit having an outer body and a liner inside the outer body to one of a fracturing manifold or a fracturing tree;

coupling the fluid conduit to the other of the fracturing manifold or the fracturing tree, wherein the fluid conduit has a bore diameter of between four inches and eight inches and completes a fluid connection between the fracturing manifold and the fracturing tree so that fracturing fluid can be routed between the fracturing manifold and the fracturing tree through the fluid conduit;
disconnecting the fluid conduit from the fracturing tree and from the fracturing manifold;
removing the liner from the outer body of the fluid conduit;
installing a replacement liner in the outer body in place of the removed liner; and
coupling the fluid conduit with the replacement liner between an additional fracturing tree and either the fracturing manifold or an additional fracturing manifold so as to place the additional fracturing tree in fluid communication with either the fracturing manifold or the additional fracturing manifold via the fluid conduit with the replacement liner.
12. The method of claim 11 , wherein the fluid conduit has a bore diameter of seven inches.
13. A method comprising:
