Abstract
The present techniques provide systems and methods for fracturing a production formation. A method includes creating a notch in a formation and causing a volumetric change in a treatment interval proximate to a production interval so as to apply a mechanical stress on the production interval, wherein the treatment interval, the production interval, or both are located within the formation. A horizontal fracture is created in the formation originating from the notch.
Claims26
A method for fracturing a production formation, comprising:
- creating a notch in a formation;
- causing a volumetric change in a treatment interval proximate to a production interval so as to apply a mechanical stress on the production interval, wherein the treatment interval, the production interval, or both are located within the formation;
- and
- creating a horizontal fracture in the formation originating from the notch.
A method for production of a hydrocarbon from a reservoir, comprising:
- expanding a treatment interval below a production interval to mechanically stress the production interval;
- creating a fracture field to enhance conductivity within the production interval;
- creating a notch in the production interval;
- fracturing the production interval at the notch to form a horizontal fracture coupling the fracture field to a production well;
- and
- producing hydrocarbon from the production interval.
A hydrocarbon production system, comprising:
- a production interval in a hydrocarbon bearing subterranean formation;
- a treatment interval proximate to the production interval;
- a stimulation well drilled to the treatment interval;
- a production well drilled to the production interval;
- a notching system configured to create notches in a formation comprising the production interval, the treatment interval, or both;
- a stimulation system configured to create a volumetric change in the treatment interval;
- and
- a fracturing system configured to fracture the formation at the notches to create horizontal fractures.
