Abstract: A downhole motor assembly for driving a drill bit. The assembly includes a hydraulic drive section with a stator and a rotor located inside the stator to form a flow path between the stator and the rotor. Fluid flowing through the flow path in response to a pressure differential across the hydraulic drive section creates an operative force to rotate the drill bit. The assembly also includes a regulation mechanism that includes a valve and a fluid flow diversion bore for diverting at least some fluid from the flow path when the pressure differential across the hydraulic drive section is greater than or equal to a transition pressure differential.

Abstract: A borehole array for ranging and crosswell telemetry is disclosed along with certain methods for employing such a borehole array. Some embodiments of the borehole array include electrically coupled reference nodes distributed along the length of a reference well. Each reference node includes a solenoid operated by a control unit. The control unit employs the solenoid to generate a magnetic field for guiding a bottomhole assembly in a nearby well. The control unit further serves as a communications intermediary between the bottomhole assembly and a surface facility. The bottomhole assembly can be guided in turn by subsequent reference nodes of the array and employ the closest reference node as a communications link to the surface. Moreover, the use of multiple reference nodes offers greater precision in determining the bottomhole assembly's position relative to the reference well. The borehole array can be used to guide multiple drilling operations concurrently.

Abstract: A system and method for providing redundant wired pipe-in-pipe telemetry is described. The redundant wired pip-in-pipe telemetry system includes an outer pipe and an inner pipe disposed within the outer pipe. Within the outer pipe, two or more conductive elements may be provided as well as a wired path controller that may selectably switch between available conductive paths. The wired path controller may identify conductive paths with good electrical characteristics and select those paths for transmission. If a conductive path develops a fault, the wired path controller may select one of the alternative redundant conductive paths for transmission to avoid the fault. The wireless controller may further transmit information about the location of faults to a drill operator at the surface.
