| According to one or more aspects of the invention an interlock device is adapted for connection within a load path of a tubular support device to lock the tubular support device in a closed position in response to detecting a load suspended from the tubular support device. The interlock device includes a first member moveably connected to a second member and a biasing mechanism operationally connected to the first member and the second member providing a load setting resisting movement of the first member and the second member relative to one another. The first and the second member may be rotationally locked with one another to transmit rotation across the interlock device to the elevator. | ||||||

| A torque anchor for anchoring well equipment in a well conduit to arrest movement in both longitudinal directions and rotation in a first direction, but not rotation in an opposed second direction. A mandrel connected to the equipment has one or more grooves for slideably receiving respective pins from a drag body on the mandrel. A slip cage on the mandrel houses slips for selectively engaging and disengaging the conduit. Manipulation of the mandrel at surface causes the pins to move within the one or more grooves on the mandrel and the drag body to move toward the slip retainer driving the slips outward to grip the conduit. Further pulling at surface maintains the set position. The anchor is unseta surface by releasing the pull, rotating the mandrel in the second direction, and pushing the mandrel to disengage the slips. | ||||||

| A string is equipped with a braking device to regulate its speed into the wellbore through an existing tubular. When the targeted amount of overlap with an existing tubular is accomplished the two tubulars are then joined together. The braking system can take many forms such as externally mounted mechanisms that are speed responsive to vary the braking force. The inside of the tubular can have trapped gas to provide buoyancy and reduce the dropping speed. The braking can be accomplished hydraulically through regulated flow through the tubular or by a combination of a hydraulic and mechanical device. The momentum of the dropped string can also be controlled with a swage device that at the appropriate location lands on a taper and wedges or fuses itself to the surrounding tubular to gain support from the surrounding tubular. | ||||||

| A method for restraining tubular members during well servicing. A first step involves monitoring a velocity of tubular members as they are withdrawn from a well. A second step involves activating a tubing restrainer when the velocity of the tubular members exceeds a predetermined threshold. | ||||||

| An instrument hanger for use in tubing is disclosed with an anti-kick, anti-fall running tool. In one embodiment, the tool includes an internal mandrel, an external sleeve, with the mandrel being tapered wherein the external sleeve supports upwardly pointed detents and downwardly pointed detents against the taper which detents prevent untimely fall of the tool and untimley upward movement thereof.The tool combination includes a packer element including a set of expandable slips or collet fingers functioning in conjunction with the packer to expand and plug the tubing string. Further tool combination may support an instrument package such as a downhole pressure measuring mechanism used to obtain downhole pressure readings after isolating above a particular zone.The tool combination further includes a valved flow path across the packer element which is selectively released at the time of release of the tool combination which vents any bottom hole pressure differential and enables retrieval of the tool combination. During retrieval, the instrument package cannot be dropped because the anti-fall detents are set against prefall. | ||||||
