Abstract

Fracturing fluid delivery systems having flexible fracturing fluid delivery conduits secured with quick connectors are provided. In one example, a fracturing system includes a wellhead assembly and a fracturing fluid conduit coupled to the wellhead assembly to route fracturing fluid to the wellhead assembly. The fracturing fluid conduit includes a flexible body defining a bore for conveying the fracturing fluid to the wellhead assembly. The fracturing fluid conduit is coupled to the wellhead assembly via an actuated connector including one or more locking members that move from an unlocked position to a locked position to secure the fracturing fluid conduit to the wellhead assembly. Additional systems, devices, and methods are also disclosed.

First claim

The invention claimed is:

1. A fracturing system comprising:
a wellhead assembly; and
a fracturing fluid conduit coupled to the wellhead assembly to enable receipt of fracturing fluid by the wellhead assembly from the fracturing fluid conduit, the fracturing fluid conduit including a flexible body defining a bore for conveying the fracturing fluid to the wellhead assembly, wherein the fracturing fluid conduit is coupled to the wellhead assembly via an actuated connector including one or more locking members that move from an unlocked position to a locked position to secure the fracturing fluid conduit to the wellhead assembly, the actuated connector includes an axially driven piston arranged so as to selectively push the one or more locking members from the unlocked position to the locked position to secure the fracturing fluid conduit to the wellhead assembly, and the one or more locking members include a split lock ring.

2. The fracturing system of claim 1 , wherein an end of the fracturing fluid conduit includes a mandrel having a shoulder engaged by at least one of the one or more locking members in the locked position to secure the fracturing fluid conduit to the wellhead assembly.

3. The fracturing system of claim 1 , wherein the fracturing fluid conduit includes a pin end that is received in a box end of the wellhead assembly and the one or more locking members are housed in the box end so as to secure the fracturing fluid conduit to the wellhead assembly by moving the one or more locking members radially inward from the unlocked position to the locked position.

4. The fracturing system of claim 1 , comprising a fracturing manifold coupled to the wellhead assembly via the fracturing fluid conduit.

5. The fracturing system of claim 4 , wherein the fracturing fluid conduit is coupled to the fracturing manifold via an additional actuated connector including one or more locking members that move from an unlocked position to a locked position to secure the fracturing fluid conduit to the fracturing manifold.

6. The fracturing system of claim 5 , wherein the fracturing fluid conduit includes a first end connected to the wellhead assembly by the actuated connector and a second end connected to the fracturing manifold by the additional actuated connector, and the fracturing fluid conduit is without a flanged connection or a hammer union between the first end and the second end.

7. The fracturing system of claim 1 , wherein the wellhead assembly includes a fracturing tree and the fracturing fluid conduit is coupled to the fracturing tree via the actuated connector.

8. A method comprising:
moving a first end of a flexible fracturing fluid conduit toward a wellhead assembly; and
actuating a connector to move one or more locking members of the connector from an unlocked position to a locked position to secure the first end of the flexible fracturing fluid conduit to the wellhead assembly via the connector, wherein actuating the connector includes axially driving a piston of the connector to push the one or more locking members from the unlocked position to the locked position to secure the first end of the flexible fracturing fluid conduit to the wellhead assembly via the connector, and the one or more locking members include a split lock ring.

9. The method of claim 8 , comprising:
moving a second end of the flexible fracturing fluid conduit toward a fracturing manifold; and
actuating an additional connector to move one or more locking members of the additional connector from an unlocked position to a locked position to secure the second end of the flexible fracturing fluid conduit to the fracturing manifold via the additional connector.

10. The method of claim 8 , comprising performing a fracturing operation including pumping fracturing fluid into a well through the flexible fracturing fluid conduit and the wellhead assembly.

11. The method of claim 10 , comprising performing the fracturing operation such that all fracturing fluid pumped into the well during the fracturing operation passes through the flexible fracturing fluid conduit.
