Abstract
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.
