Abstract: A setting tool for hanging a tubular string includes: a mandrel having an upper portion and a lower portion for extending into the tubular string; a housing connected to the mandrel upper portion; and a bonnet. The bonnet is: for receiving an upper end of the tubular string, disposed along the mandrel, and linked to the housing. The setting tool further includes: an actuator for stroking the bonnet relative to the mandrel and the housing, thereby setting a hanger of the tubular string; an electronics package in communication with the actuator for operating the actuator in response to receiving a command signal; and a latch. The latch is: connected to the mandrel lower portion, operable between an extended position and a retracted position, for being restrained in the retracted position by being disposed in the tubular string, and extendable by being removed from the tubular string.

Abstract: A running tool for deploying a tubular string into a wellbore includes a tubular body and a latch for releasably connecting the tubular string to the body. The latch includes a longitudinal fastener for engaging a longitudinal profile of the tubular string and a torsional fastener for engaging a torsional profile of the tubular string. The running tool further includes a lock movable between a locked position and an unlocked position and the lock keeps the latch engaged in the locked position. The running tool further includes an actuator operable to at least move the lock from the locked position to the unlocked position and an electronics package in communication with the actuator for operating the actuator in response to receiving a command signal.
