A fill up tool includes a mandrel; a primary sealing member disposed around the mandrel; and a selectively operable secondary sealing member activated by rotation of the mandrel. In another embodiment, the selectively operable secondary sealing member is activated using hydraulic pressure.

Fill up tool

In one embodiment, a coupling system for a top drive and a tool includes a drive stem of the top drive configured to transfer torque to the tool, a key disposed on the drive stem and movable to an extended position, an adapter of the tool configured to receive the drive stem, a key recess disposed on the adapter and configured to receive the key in the extended position, and a biasing member configured to bias the key towards the extended position.

Combined multi-coupler with locking clamp connection for top drive

In one embodiment, a flowback tool for running a tubular string into a wellbore includes a tubular housing having a bore therethrough and a tubular mandrel. The mandrel: has a bore therethrough in communication with the housing bore, is longitudinally movable relative to the housing, is torsionally coupled to the housing, and has a threaded coupling for engaging a threaded coupling of the tubular string. The flowback tool further includes a nose: longitudinally coupled to the housing, operable to receive an end of the tubular string, and including a seal operable to engage a surface of the tubular string, thereby providing fluid communication between a bore of the tubular string and the mandrel bore. The flowback tool further includes an actuator operable to move the mandrel and the nose longitudinally relative to the housing for engaging and disengaging the tubular string.
