Abstract

A fracturing fluid delivery system is provided. In one embodiment, the system includes a wellhead assembly, a fracturing fluid supply line, a vertical branch extending upward from the fracturing fluid supply line, and a fluid conduit coupling the vertical branch in fluid communication with the wellhead assembly. The fluid conduit may extend linearly from the vertical branch 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 mounted over a well;
a fracturing fluid supply line;
a vertical branch in fluid communication with and extending upward from the fracturing fluid supply line; and
a fluid conduit coupling the vertical branch in fluid communication with the wellhead assembly such that the fluid conduit provides the only fluid path from the vertical branch to the wellhead assembly during fracturing;
wherein the fluid conduit extends linearly from the vertical branch to the wellhead assembly.

2. The fracturing system of claim 1 , wherein the vertical branch includes an outlet port facing an inlet port of the wellhead assembly, and the fluid conduit extends linearly from the outlet port of the vertical branch to the inlet port of the wellhead assembly.

3. The fracturing system of claim 2 , wherein the vertical branch includes an elbow having the outlet port of the vertical branch.

4. The fracturing system of claim 1 , wherein the wellhead assembly includes a fracturing tree.

5. The fracturing system of claim 1 , wherein the fluid conduit is an adjustable fluid conduit.

6. The fracturing system of claim 1 , comprising a fracturing fluid supply coupled to provide fracturing fluid to the fracturing fluid supply line.

7. A fracturing system comprising:
a wellhead assembly mounted over a well;
a fracturing fluid supply line; and
a fluid path coupling the fracturing fluid supply line to the wellhead assembly so as to provide fracturing fluid from the fracturing fluid supply line to the well;
wherein the fluid path includes an upright leg and a lateral leg that are coplanar, the upright leg of the fluid path extends upward from the fracturing fluid supply line and is arranged to receive fracturing fluid flowing upward out of the fracturing fluid supply line, and the lateral leg of the fluid path extends linearly between the upright leg of the fluid path and the wellhead assembly.

8. The fracturing system of claim 7 , wherein the wellhead assembly includes a valve.

9. The fracturing system of claim 7 , comprising an elbow with a bore joining the upright leg of the fluid path and the lateral leg of the fluid path.

10. The fracturing system of claim 7 , comprising a linearly adjustable conduit through which the fluid path passes.

11. A method comprising:
coupling a fracturing fluid supply line to a wellhead assembly mounted over a well, wherein coupling the fracturing fluid supply line to the wellhead assembly includes:
coupling a fluid conduit to the wellhead assembly; and
coupling the fluid conduit to a vertical branch connected to the fracturing fluid supply line such that the fluid conduit is between the wellhead assembly and the vertical branch to provide a linear flow path from the vertical branch to the wellhead assembly, the vertical branch provides a rising flow path from the fracturing fluid supply line, and the rising flow path provided by the vertical branch and the linear flow path provided by the fluid conduit from the vertical branch to the wellhead assembly are coplanar.

12. The method of claim 11 , wherein coupling the fluid conduit to the vertical branch includes coupling the fluid conduit to the vertical branch via a connection block.

13. The method of claim 11 , comprising pumping fracturing fluid into the well through the fracturing fluid supply line, the vertical branch, the fluid conduit, and the wellhead assembly.
