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.
Claims20
A downhole tool for electric-based fracturing, the downhole tool comprising:
- an outer enclosure;
- an insulator chamber disposed at least partially within the outer enclosure;
- a high-voltage cable disposed at least partially within the insulator chamber;
- and
- an electrode disposed at least partially within the insulator chamber,
- wherein a portion of the electrode is coupled to a portion of the high-voltage cable within an interior volume of the insulator chamber such that the portions of the electrode and the high-voltage cable that are coupled are configured to be insulated from a surrounding environment of the downhole tool, wherein the electrode is configured to transfer electric energy to the surrounding environment through an exposed portion of the electrode.
A method of electric-based fracturing, the method comprising:
- coupling a high-voltage cable and an electrode of a downhole tool to one another within an interior volume of an insulator chamber such that at least a portion of each of the high-voltage cable and the electrode are thermally and/or electrically insulated from a surrounding environment of a well in which the downhole tool is positioned;
- transmitting electricity from a surface power source along the high-voltage cable to the electrode of the downhole tool within the well;
- transferring at least a portion of the transmitted electricity from the electrode to the surrounding environment through an exposed portion of the electrode;
- and
- heating the surrounding environment with the transferred electricity.
