International Classification:

E21B 2301

US Classification:

166382, 166118, 166208

Abstract:

An oil or gas well slip system is provided having a slip bowl with an interactive contact surface and a slip assembly having a mating interactive contact surface for slidable engagement with the slip bowl interactive contact surface, wherein the slip bowl and the slip assembly are each comprised of a first material. A second material is attached to the interactive contact surface of either the slip bowl or the slip assembly, wherein the second material is compositionally different from the first material to prevent cold welding between the slip bowl and the slip assembly and wherein the second material has little or no tendency to dissolve into the atomic structure of the first material.

Assignee:

Varco I/P, Inc - Houston TX

International Classification:

B25B 1350

US Classification:

81 5735, 81 574

Abstract:

An iron roughneck has a pair of upper jaws carrying pipe gripping dies for gripping tool joints. The jaws have recesses formed on each side of the pipe gripping dies to receive spinning rollers. By positioning the spinning rollers in the upper jaws at the same level as pipe gripping dies, the spinning rollers are able to engage the pipe closer to the lower jaws and thus can act on the tool joint rather than on the pipe stem.

US Classification:

166 7514, 166 7753, 175423, 294902

Abstract:

A rotary slip for supporting a drill string having a plurality of slip segments connected to define an opening for insertion of the drill string, wherein each slip segment comprises a head region, a toe region, and an inner radial surface axially extending between the head and toe regions, and wherein the inner radial surface of each slip segment comprises a circumferential groove. A plurality of axially aligned drill string gripping inserts are attached to each slip segment between the head region and the circumferential groove, wherein each insert comprises a gripping surface for contacting the drill string. A load ring is disposed within the circumferential groove of each slip element, the load ring comprising at least one securing element which is engaged by one of the plurality of axially aligned inserts to secure the load ring within the circumferential groove.

International Classification:

E21B003/04

US Classification:

166 781, 175195

Abstract:

A rotary seal assembly for a rotary support table for use in drilling systems and the like to provide pressurized fluid to a rotary slip assembly disposed within the rotary support table is provided. The rotary seal assembly is designed to be coupled to an existing rotary support table which is used to rotate a drill string, and includes a powered slip that is powered into an engaged position to securely engage a pipe segment, for example, a casing segment. The rotary seal assembly generally comprises a ribbon of expandable material having an outer surface in fluid communication with a source of pressurized fluid, and an inner surface cooperative with a rotary housing, the rotary seal having a plurality of openings capable of communicating fluid between said outer and inner surfaces, wherein the outer seal surface has a surface area greater than the inner surface such that when the pressurized fluid is conducted to the outer surface of the seal a differential pressure between the outer and inner surfaces is created such that the inner surface of the seal is expanded to engage the rotary housing and form an annular fluid duct providing fluid communication between the pressurized fluid source and the rotary housing. A method of operating a rotary table and powered slip assembly utilizing the rotary slip assembly of the current invention is also provided.
