Title:
METHOD OF SUBTERRANEAN FRACTURING
Document Type and Number:
WIPO Patent Application WO/2020/018755
Kind Code:
A8
Abstract:
A system and method of wellbore 12 operations that forms notches 30 into a subterranean formation 14 that circumscribes a wellbore 12 prior to fracturing the formation 14. The notches 30 extend past the hoop stress regime 34 that surrounds the wellbore 12 so that fractures formed by fracturing are oriented in a designated plane. In one example, a fluid jet 28 is used to form the notches 30, and which is discharged from a nozzle 70 that rotates about a downhole tool. The nozzle 70 is set in a sleeve 68 that is rotatable about the downhole tool, and pressurized fluid 78 is delivered to a plenum 84 disposed on an inner surface of the sleeve 64. The nozzle 70 is oriented oblique to a radius of the sleeve 64, so that the fluid being discharged from the nozzle 70 generates a force that rotates the sleeve 64.
