Abstract

A fracturing system can include an integral fracturing manifold. More particularly, a fracturing system can include a plurality of fracturing trees and an integral fracturing manifold may be directly coupled to each of the plurality of fracturing trees. The integral fracturing manifold may also include adjustment and pivot joints that accommodate spacing and elevation differences between the fracturing trees.

First claim

The invention claimed is:

1. A fracturing system, comprising:
a plurality of well fracturing trees coupled to wellheads; and
an integral fracturing manifold that is integral with and directly coupled to each of the plurality of well fracturing trees so as to provide fracturing fluid from the integral fracturing manifold to wells through the well fracturing trees and the wellheads without use of manifold output lines between the fracturing manifold and the well fracturing trees, wherein the integral fracturing manifold is coupled to the well fracturing trees such that a plurality of valves enable individual control of flow of fracturing fluids from the integral fracturing manifold into the wells through the well fracturing trees and the wellheads.

2. The system of claim 1 , wherein the plurality of fracturing trees bear at least a portion of the weight of the integral fracturing manifold.

3. The system of claim 1 , wherein the integral fracturing manifold includes a plurality of connection blocks and a plurality of pipe sections.

4. The system of claim 3 , wherein each of the plurality of well fracturing is directly coupled to the integral fracturing manifold via a respective connection block of the plurality of connection blocks.

5. A fracturing system, comprising:
a well fracturing tree coupled to a wellhead; and
a fracturing manifold attached at the well fracturing tree by one or more valves of the well fracturing tree to enable flow of fracturing fluid from the fracturing manifold to the well fracturing tree via the one or more valves without the use of frac iron or a fracturing head between the fracturing manifold and the well fracturing tree; and
at least one additional well fracturing tree coupled to the fracturing manifold by one or more additional valves of the at least one additional well fracturing tree;
wherein each well fracturing tree is coupled to a shared trunk line of the fracturing manifold.

6. A method, comprising:
coupling a fracturing manifold to a first well fracturing tree coupled to a first wellhead to enable routing of fracturing fluid from the fracturing manifold to a first well through the first well fracturing tree and the first wellhead without a manifold output line between the fracturing manifold and the first well fracturing tree; and
coupling the fracturing manifold to a second well fracturing tree coupled to a second wellhead and adjacent to the first well fracturing tree to enable routing of fracturing fluid from the fracturing manifold to a second well through the second well fracturing tree and the second wellhead without a manifold output line between the fracturing manifold and the second well fracturing tree;
wherein coupling the fracturing manifold to the first and second well fracturing trees includes attaching the fracturing manifold to valves that enable individual control of flow of fracturing fluids from the fracturing manifold to the first and second well fracturing trees.

7. The method of claim 6 , comprising fracturing the first or second well with fracturing fluid provided from the fracturing manifold through the first or second well fracturing tree.
