A system for use in a drilling operation that includes uphole electronic equipment and a drill string suspended in an earth borehole, a section of wired drill pipe that is part of a communication link between a downhole tool and the uphole electronic equipment, an interface for communicating between the section of wired drill pipe and a communication source/destination. The system includes a housing having a generally cylindrical outer shape which has a passage there through. The housing has a WDP end connectable to the section of wired drill pipe and a further end connectable to the communication source/destination. The system also includes a WDP circuit module disposed within the housing. The WDP circuit module electrically coupleable with the wired drill pipe section. The system includes a further circuit module, disposed within the housing, which is electrically coupled with the WDP circuit module and electrically coupleable with the communication source/destination.

Interface and method for wellbore telemetry system

A cable link may include a first link connector in signal communication with at least one sensor in a drill string and coupled to the drill string, a second link connector spaced apart from the first link connector and in signal communication with a telemetry system, the second connector link coupled to the drill string, and a linking cable having signal connectors at each end thereof, the linking cable having at least one of an electrical conductor and an optical fiber therein, the signal connectors each configured to latch proximate a respective one of the first and second link connector.

Cable link for a wellbore telemetry system

A method for determining electrical condition of a wired drill pipe includes inducing an electromagnetic field in at least one joint of wired drill pipe. Voltages induced by electrical current flowing in at least one electrical conductor in the at least one wired drill pipe joint are detected. The electrical current is induced by the induced electromagnetic field. The electrical condition is determined from the detected voltages.

Method and apparatus for locating faults in wired drill pipe

The disclosure has application for use in conjunction with an operation of drilling an earth borehole using: a drilling rig, a drill string having its generally upper end mechanically coupleable with and suspendable from the drilling rig, and a bottom hole assembly adjacent the lower end the drill string, the bottom hole assembly including a drill bit at its lower end. A method is set forth for obtaining information about at least one parameter sensed at the bottom hole assembly, including the following steps: providing at least one measuring device in the bottom hole assembly, the at least one measuring device producing measurement data representative of a measured condition at the bottom hole assembly; providing an uphole processor system at the earth's surface; providing a drill string telemetry system coupled with the at least one measuring device and coupled with the uphole processor system; and transmitting the data from the measuring device to the uphole processor system via the drill string telemetry system.

Bidirectional drill string telemetry for measuring and drilling control

A wired drill pipe for a drill string of a downhole tool positioned in a wellbore penetrating a subterranean formation is provided. The wired drill pipe includes a drill pipe, a cable and a wire retainer. The drill pipe has a slot at each end thereof. The slots are adapted to receive at least one transformer. The drill pipe has an inner surface defining a passage for the flow of mud therethrough. The cable extends from the transformer into the passage of the drill pipe. The wire retainer is positioned on the inner surface of the drill pipe. The wire retainer is adapted to secure the cable therein.

Method and conduit for transmitting signals

A wired drill pipe segment includes a tubular body having an axial bore, a box end disposed at a first end of the tubular body having a first core material disposed in the box end, a pin end disposed at a second end of the tubular body having a second core material disposed in the pin end, a first coil winding wound around at least a portion of the first core material and a second coil winding wound around at least a portion of the first core material, a third coil winding wound around at least a portion of the second core material and a fourth coil winding wound around at least a portion of the second core material, a first conductor connected to the first coil winding and the third coil winding and extending through the tubular body, and a second conductor connected to the second coil winding and the fourth coil winding and extending through the tubular body.
