Immovable string hydraulic jetting tool: is well stimulation which combined of perforating, fracturing and isolation. High-speed liquid that from specialized jetting tools could shoot through casing, rock and shape hole. Bottom hole pressure is increased by annular fluid infusion, which exceed stratum fracturing pressure and crack layer. This method has advantage of deeper than ordinary perforating, aperture is larger and less hurt to stratum.
