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 accommodate spacing and elevation differences between the fracturing trees.
Claims16
A fracturing system, comprising:
- a plurality of fracturing trees;
- and
- an integral fracturing manifold directly coupled to each of the plurality of fracturing trees, wherein the integral fracturing manifold includes at least one adjustment joint that enables variation in the length of the integral fracturing manifold to accommodate variation in the distance between fracturing trees of the plurality of fracturing trees, wherein the integral fracturing manifold includes at least one pivot joint.
A fracturing system, comprising:
- a fracturing tree;
- a fracturing manifold coupled to the fracturing tree by one or more valves of the fracturing tree to enable flow of fracturing fluid from the fracturing manifold to the fracturing tree via the one or more valves without the use of frac iron or a fracturing head between the fracturing manifold and the fracturing tree;
- and
- at least one additional fracturing tree coupled to the fracturing manifold by one or more additional valves of the at least one additional fracturing tree;
- wherein each fracturing tree is coupled to a shared trunk line of the fracturing manifold and the shared trunk line includes a plurality of wellhead crosses and pipes extending between the plurality of wellhead crosses.
2 more elements
A method, comprising:
- coupling a fracturing manifold to a first fracturing tree to enable routing of fracturing fluid from the fracturing manifold to the first fracturing tree without frac iron;
- coupling the fracturing manifold to a second fracturing tree adjacent to the first fracturing tree to enable routing of fracturing fluid from the fracturing manifold to the second fracturing tree without frac iron;
- and
- varying the length of the fracturing manifold by manipulating an adjustment joint of the fracturing manifold, wherein the fracturing manifold includes at least one pivot joint.
1 more element
A fracturing system, comprising:
- a plurality of fracturing trees;
- and
- an integral fracturing manifold directly coupled to each of the plurality of fracturing trees, wherein the integral fracturing manifold includes at least one pivot joint and the at least one pivot joint enables a first portion of the integral fracturing manifold to be positioned at an angle with respect to a second portion of the integral fracturing manifold to accommodate variation in spacing between fracturing trees of the plurality of fracturing trees.
