Abstract: A well-drilling system comprises a tubular string, a torque sub system, and one or more downhole devices. The tubular string extends into the well bore and comprises at least one of a radio-frequency device and a communication line. The one or more downhole devices are attached to the tubular string and collect data and transmit signals representative of the data to the torque sub system. The torque sub system is configured to communicate with one or more downhole devices and to transmit the data from the downhole devices to a computing device. The torque sub system is configured to communicate with the at least one of the radio-frequency device and the communication line. The torque sub system is configured to communicate with the down hole devices via the communication line. The torque sub system is configured to measure acceleration, vibration, and displacement data and to transmit that data to the computing device.

Abstract: A well drilling system includes a torque drive system; a tubular string positioned below and rotated by the torque drive system; a pipe handler and back-up clamp assembly positioned between the torque drive system and the tubular string for coupling with and supporting one end of the tubular string; at least one internal blow-out preventer (IBOP) valve positioned between the torque drive system and the back-up clamp assembly; and a measurement device for measuring parameters of drilling, casing running or tubular make-up and break-out operations. The measurement device measures parameters below the IBOP valve so that parameters such as internal fluid pressures may be monitored even when the IBOP valve is closed. The measurement device is separate from the IBOP valve and is connected above the back-up clamp assembly and tubular string.
