Internal tractor system for downhole tubular body

Номер: GB0002550790A
Автор: BRUCE L RANDALL [US], BRUCE L RANDALL, Bruce L Randall
Принадлежит:

An internal tractor system is provided herein. The internal tractor system is useful for advancing and withdrawing a tubular body within a wellbore. Preferably, the wellbore includes a horizontal section, and the internal tractor system is used to advance a string of coiled tubing or a flexible jetting hose along the horizontal section. The internal tractor system generally includes an elongated carrier body. The carrier body defines a wall forming a plurality of radially-disposed prongs, and a passageway within the wall. The passageway is dimensioned to closely receive the tubular body along the length of the carrier body to prevent buckling. The internal tractor system also includes a wiring chamber housing electrical wires, data cables, or both within one of the plurality of prongs, and at least one pair of grippers residing within opposing prongs.

Downhole hydraulic jetting assembly

Номер: GB0002550795A
Автор: BRUCE L RANDALL [US], BRUCE L RANDALL, Bruce L Randall
Принадлежит:

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.
