Abstract: A managed bulk drilling system that employs a guide wire for ranging and crosswell telemetry. Some system embodiments include multiple drilling assemblies operating in the vicinity of a reference well that contains an electrical cable. The electrical cable is coupled to a surface control system. The control system uses the electrical cable as part of an antenna to receive uplink signals from the drilling assemblies and to broadcast down-link signals to the drilling assemblies. The uplink signals can include position data and the downlink signals can include individual steering commands to adjust the trajectories of each drilling assembly. The cable can also generate a guidance field for the drilling assemblies to detect and follow.

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 system and method for automatic weight-on-bit sensor calibration automatically compensate the measurements of a weight-on-bit sensor based on one or more of mass, hole inclination, buoyancy, drag, and mud flow, resulting in a more accurate axial force measurement below the weight-on-bit sensor at various hole inclinations. This measurement is observed by removing some of the effects masking the actual force being applied to the axial face of the drill bit.

Abstract: A well drilling system can include a drilling tool with at least one component which is displaced by a material that changes shape. The material can be a shape memory material. The material may change shape in response to a temperature change. The component can be a drill bit cutter, a depth of cut control surface, a gauge surface or a stabilizer surface. A method of controlling a drilling operation can include configuring a drilling tool with a material which changes shape, and the material displacing at least one component of the drilling tool during the drilling operation. Displacement of the component can be controlled downhole to maintain drilling parameters (such as torque, vibration, steering performance, etc.) in desired ranges.

Abstract: A system for signal transmission along a drill string is disclosed. A first drill pipe section and a second drill pipe section each comprise an inner pipe. A first repeater sub is coupled to the first drill pipe section and the second drill pipe section at a first position along the drill string. The first repeater sub comprises a first toroid corresponding to the first drill pipe section and a second toroid corresponding to the second drill pipe section. A signal transmitted through the first drill pipe section, an inner mandrel of the repeater sub and the inner pipe of the first drill pipe section is received by the first toroid. The first repeater sub processes the signal received by the first toroid to generate a processed signal and transmits the processed signal to the second drill pipe through the second toroid.

Abstract: A drilling assembly (2) comprises upper (4) and lower (6) drill strings with a fluid passage (80) therethrough for distributing fluid to a bottom hole assembly (10). The upper drill string (4) has an upper end (11) connectable to a drilling apparatus (13) and fluid source (16) and a lower end (18) with an attached casing expander unit (20) that communicates the fluid passage (80) of the upper (4) and lower (6) drill strings. An upper end (22) of the lower drill string (6) is formed from a casing string (24) telescoped over the casing expander unit. A constriction (31) connects the casing string (24) with the rest of the lower drill string (6). A flow restriction device (35) in the lower drill string acts to control fluid flow through the fluid passage. In use, the flow restriction device creates a pressure in the fluid passage that acts at the constriction to advance the lower drill string past the upper drill string while simultaneously expanding the portion of the casing string moving past the expander unit.
