Abstract: A tubular handling device. The device includes a plurality of slips, and wherein the slips have an arcuate inner face that has a longitudinally disposed slot and a ledge therein. The device further comprises an insert having a shoulder that is configured to fit within the ledge, and wherein the insert is capable of transferring a load from the shoulder to the ledge. In one preferred embodiment, the outer portion of the slips have a taper of greater than 11 degrees and a complementary bowl insert is provided that has a matching taper. A method of handling tubular members on a drilling rig is also disclosed.

Abstract: An insert bowl, bushing, or spider includes a bowl having a central bore defined by an inner surface having an upper tapered section for engaging slips supporting a work string and a lower section. A wear indicator, such as a groove or substantially horizontal groove, is formed in the inner surface of the bowl and provides a visual indicator of wear to the bowl. A second wear indicator, such as a groove or substantially horizontal groove, may also be formed in the inner surface of the bowl. The inability to visually detect all or a portion of the wear indicator signifies that maximum recommended wear to the bowl has been reached and the bowl should be replaced to avoid damage to the work string.

Abstract: A device for torquing a tubular connection. The device comprises an upper assembly having an upper jaw member, a lower assembly having a lower jaw member, an upper gear for advancing the upper jaw member, and a lower gear for advancing the lower jaw member. The upper jaw member includes a first jaw operatively associated with a first rack, a second jaw operatively associated with a second rack, and a third jaw operatively associated with a third rack. The lower jaw member includes a fourth jaw operatively associated with a fourth rack, a fifth jaw operatively associated with a fifth rack, and a sixth jaw operatively associated with a sixth rack. A method of torquing a first tubular with a second tubular is also disclosed.

Abstract: The present invention relates to a transverse bitbreaker plate, which is attached to the lower surface of a power wrench to effect the coupling or decoupling of downhole tools such as bits or stabilizers. The plate is hinged and provides a generally triangular shaped profile along through its transverse surface which mates with the bit or stabilizer, which is to be connected or disconnected. The hinged plate is removably attached below the power wrench with pins so that it may be used and removed in a minimum of time.
