Abstract: A safety joint for use in a subterranean well can include separable portions which, when separated, disconnect sections of a tubular string. Elongation of the safety joint can be permitted while longitudinal compression of the safety joint is prevented. A method of activating a safety joint in a subterranean well can include providing the safety joint with portions having end connectors which interconnect the safety joint between sections of a tubular string, permitting elongation of the safety joint, thereby facilitating disconnection of the tubular string sections, and then preventing longitudinal compression of the safety joint. Another safety joint can include separable portions, and a locking device which permits relative displacement between a generally tubular mandrel and a component of the safety joint in one direction, and prevents relative displacement between the mandrel and the component in an opposite direction.

Abstract: A method of performing real-time position sensing includes conveying a tool attached to a tubular string in a borehole. The tool includes a position sensing sub, and the position sensing sub includes sensing devices. The method further includes recording measurements taken by the sensing devices. The method further includes determining, based on the measurements, a position along the borehole of a particular portion of the tubular string. Data from sensing devices having a higher priority overrides conflicting data from sensing devices having a lower priority. The method further includes transmitting the position wirelessly.
