摘要： A hydraulic jetting assembly is provided herein. The jetting assembly includes a jetting hose, with a jetting nozzle at its distal end. The jetting nozzle comprises a tubular stator body having a fluid discharge slot, and a tubular rotor body residing within a bore of the stator body. The jetting nozzle has one or more bearings residing between the rotor body and the surrounding stator body to accommodate relative rotational movement. The jetting nozzle includes a proximal end configured to sealingly connect to an end of a jetting hose, and to receive a high pressure jetting fluid. Preferably, the nozzle has an outer diameter that is equivalent to or slightly larger than an outer diameter of the jetting hose. Preferably, the jetting assembly has at least three actuator wires configured to induce a controlled bending moment at its distal end, thereby providing for a steerable downhole tool.

摘要： A downhole hydraulic jetting assembly is provided herein. The assembly is useful for steerably jetting multiple lateral boreholes into a subsurface formation from an existing parent wellbore of any inclination. The assembly is useful for single trip completions or recompletion through the placement of multiple lateral boreholes. The assembly includes an external system wherein coiled tubing and a whipstock member are run into a wellbore. The assembly further includes an internal system that is run into the wellbore housed within the external system, but which allows a nozzle at the end of the hose to be directed against a wellbore exit location after the whipstock member is located and set. A window may be formed through casing using the jetting hose and nozzle, followed by the formation of a lateral bore hole. The whipstock may be re-located and/or re-oriented for the jetting of additional casing exits and lateral boreholes in the same trip.

摘要： A method of forming a lateral borehole in a pay zone located within an earth subsurface is provided. The method includes determining a depth of a pay zone in the earth subsurface, and then forming a wellbore within the pay zone. The method also includes conveying a hydraulic jetting assembly into the wellbore on a working string. The assembly includes a jetting hose carrier, and a jetting hose within the jetting hose carrier having a nozzle connected at a distal end. The method additionally includes setting a whipstock in the wellbore along the pay zone, and translating the jetting hose out of the jetting hose carrier to advance the nozzle along the face of the whipstock. The method then includes injecting hydraulic jetting fluid through the jetting hose and connected jetting nozzle, thereby excavating a lateral borehole within the rock matrix, and further injecting the fluid while further translating the jetting hose and connected nozzle along the face of the whipstock without coiling or uncoiling the hose, thereby forming a lateral borehole that extends at least 5 feet from the wellbore.
