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.

Abstract: A method of severing a drill-string comprises reducing the load bearing cross-sectional area of the neck of a connection. The reduction in the area of the neck may be achieved using a precisely located flow-actuated cutter. The cutter may be pumped into the string to land on a seat above the connection. A bypass valve may be provided below the connection to facilitate fluid circulation.

Abstract: A device for controlling fluid flow from a subsurface fluid reservoir into a production tubing string includes a tubular member defining a central bore. At least one nozzle extends through a side wall of the tubular member. A popper is moveable between an open position where fluids can flow into the central bore through the nozzle, and a closed position where the nozzle is fluidly sealed. A circumferential external head profile is located on the stem and a circumferential groove is located in the nozzle for mating with the head profile of the stem and maintaining the popper in a closed position. The device can also have a shear member disposed between the stem of the popper and an inner surface of the nozzle for supporting the popper in an open position before the popper is moved to the closed position.
