Abstract: A calibration signal is transmitted from a transmitter antenna. A receiver antenna receives a loopback signal that results from an air coupling of the receiver antenna and the transmitter antenna. The loopback signal is compared to a target. If the loopback signal does not meet the target, then a gain of the calibration signal is adjusted and the loopback signal is again checked against the target. When the loopback signal meets the target, the gain is taken as a calibrated transmitter gain.

Abstract: An apparatus that includes at least two well control mechanisms and at least one sensor to avoid collision between a section of a tubing string coupler or that is moving through the apparatus and a wellbore to which the apparatus is coupled. The sensors detect the presence of magnetic objects, such as sections of a tubing string, and measure their respective outer diameters (OD). The sensors detect when any larger OD sections of the tubing string before the larger OD section can collide with one of the well control mechanisms. The sensors direct their outputs to a controller that can identify an imminent collision state. When an imminent collision state is identified, the controller will send commands to stop movement of the tubular to avoid the collision. Movement of the tubular will not resume until the well control mechanism has been actuated to avoid collision with the larger OD section.
