Abstract
Methods, systems, and apparatus for inducing fractures in a subterranean formation and more particularly methods and apparatus to place a first fracture with a first orientation in a formation followed by a second fracture with a second angular orientation in the formation are provided. First and second fractures are initiated at about a fracturing location. The initiation of the first fracture is characterized by a first orientation line. The first fracture temporarily alters a stress field in the subterranean formation. The initiation of the second fracture is characterized by a second orientation line. The first orientation line and the second orientation line have an angular disposition to each other.
Claims18
A method for fracturing a subterranean formation, wherein the subterranean formation comprises a wellbore having an axis, the method comprising:
- providing a fracturing tool that is configured to receive a fluid and deliver the fluid into the subterranean formation;
- inducing a first fracture in the subterranean formation, wherein:
- the first fracture is initiated at about a fracturing location,
- the initiation of the first fracture is characterized by a first orientation line, and
- the first fracture temporarily alters a stress field in the subterranean formation;
- and
- inducing a second fracture in the subterranean formation, wherein:
- the second fracture is initiated at about the fracturing location,
- the initiation of the second fracture is characterized by a second orientation line, and
- the first orientation line and the second orientation line have an angular disposition to each other.

- and
- inducing a second fracture in the subterranean formation, wherein:
- the second fracture is initiated at about the fracturing location,
- the initiation of the second fracture is characterized by a second orientation line, and
- the first orientation line and the second orientation line have an angular disposition to each other;
- wherein the fracturing tool comprises a tool body to receive a fluid, the tool body comprising an interior, an exterior surface, and a set of passages from the interior to the exterior surface to release the fluid into the subterranean formation, wherein each passage has an oblique orientation to the exterior surface where the passage interrupts the exterior surface, the method further comprising:
- causing the angular disposition between the first orientation line and the second orientation line by repositioning the tool body before inducing the second fracture in the subterranean formation.
