Abstract (en)
A drilling assembly (100) includes a hydraulic jet (102) disposed on a downhole end of a fluid line (108), and one or more adjustable jet nozzles (104, 106) on the hydraulic jet (102) in multiple angular orientations relative to a central axis of the hydraulic jet (102). The one or more adjustable jet nozzles (104, 106) provide fluid pressure to penetrate a formation (5) and cut one or more angular channels (12).
