Abstract
Downhole tools, systems, and methods for electric-based fracturing are disclosed. A downhole tool for electric-based fracturing may include an outer enclosure, an insulator chamber disposed at least partially within the enclosure, and an electrode disposed at least partially within the insulator chamber. The electrode may extend out from the insulator chamber and the enclosure, and may be configured to transfer electric energy to an exterior environment surrounding the downhole tool. The insulator chamber may be configured to thermally and electrically insulate at least a portion of the electrode from the exterior environment.
Claims21
A system for electric-based fracturing, the system comprising:
- a power source;
- a high voltage cable comprising first, second, and third cable segments;
- a cable dispenser configured to dispense at least a portion of the second cable segment;
- an electrical stimulation tool;
- a proximal connector configured to operatively couple the power source and a proximal portion of the first cable segment;
- a first intermediate connector configured to operatively couple a distal portion of the first cable segment and a proximal portion of the second cable segment;
- a second intermediate connector configured to operatively couple a distal portion of the second cable segment and a proximal portion of the third cable segment;
- and
- a distal connector configured to operatively couple a distal portion of the third cable segment and the electrical stimulation tool,
- wherein at least a portion of the second cable segment is disposed on the cable dispenser,
- wherein the first intermediate connector is configured to be selectively connected and disconnected while the second cable segment is supported on the cable dispenser.
A method of electric-based fracturing, the method comprising:
- providing a high voltage cable comprising first, second, and third cable segments;
- coupling a power source and a proximal portion of the first cable segment using a proximal connector;
- coupling a distal portion of the first cable segment and a proximal portion of the second cable segment using a first intermediate connector;
- coupling a distal portion of the second cable segment and a proximal portion of the third cable segment using a second intermediate connector;
- and
- coupling a distal portion of the third cable segment and an electrical stimulation tool using a distal connector.
