ABSTRACT:
A system for the formation of a bore hole, particularly for use in enhancing the recovery of oil from an oil bearing underground formation using an assembly including a driving fluid chamber, sealed from a driving fluid chamber, and a drill string terminating in a hydraulic drillhead which passes drilling fluid into the formation. Pressurized fluid from the drilling fluid chamber is applied against the drillhead to pull the drill string into the formation, while pressurized fluid from the drilling fluid chamber pushes the drill string forward from the rear. In a preferred embodiment, the forward end of the guide tube includes a whipstock through which the piston body turns from a vertical to a horizontal direction into the formation to provide a radial for the injection of steam.
