Abstract:
Methods and apparatus are described to drill and complete wellbores. Such wellbores include extended reach horizontal wellbores, for example in shales, deep subsea extended reach wellbores, and multilateral wellbores. Specifically, the invention provides simple threaded subassemblies that are added to existing threaded tubular drilling and completion equipment which are used to dramatically increase the lateral reach using that existing on-site equipment. These subassemblies extract power from downward flowing clean mud, or other fluids, in an annulus to provide additional force or torque on tubular elements within the wellbore, while maintaining circulation, to extend the lateral reach of the drilling equipment and completion equipment. These added elements include combinations of The Leaky Seal™, a Cross-Over, The Force Sub™ and The Torque Sub™. The use of such additional simple elements allow lighter drilling equipment to be used to reach a given lateral distance, therefore reducing drilling costs.

Claim (Index 1):
A method to rotary drill a wellbore, comprising:\n providing a wellbore with a casing, the casing having an interior surface; providing a rotating tubular element at least a portion of which is disposed within the casing of the wellbore, the rotating tubular element having a distal end; providing a drill bit at the distal end of the rotating tubular element; providing a first annular hydraulic seal having an inner surface rigidly mounted on the exterior of the rotating tubular element and an outer surface spaced from the interior of the casing and forming an annular passageway between the outer surface of the seal and the interior surface of the casing; and supplying clean mud to the drill bit, wherein the mud passes through the passageway in the hydraulic seal prior to arriving at the drill bit, wherein the passageway causes a pressure drop in the mud at the location of the passageway.
