An improved cementing tool is presented which allows for relatively easy removal and insertion of the tool through the use of non-threaded low-torque connections. The cementing tool uses a combination of threaded connections and non-threaded, low-torque connections configured to create a stack of components including plug launchers, ball launchers and plug launch indicator/counters. Use of non-threaded low-torque connections allows for breaking down the tool by hand, requiring no special torquing equipment.

Cementing tool

A down hole fluid conditioning assembly, includable within a drilling bottom hole assembly or other tool configuration, creates a vortex to separate fluids such as drilling mud and the like into a lower density first portion and higher density second portion. The lower density first portion is directed toward the bottom hole assembly or other equipment to improve operational performance of the bottom hole assembly or other equipment. The higher-density second portion is directed away from the bottom hole assembly or other equipment, typically into a well annulus with an upward velocity component.

Method and apparatus for downhole fluid conditioning

A modular pipe gripping assembly has a universal actuator assembly having a control fluid swivel. An external pipe gripping assembly can be attached to the actuator assembly for gripping the external surface of a section of pipe. Alternatively, the external pipe gripping assembly can be quickly and easily removed and replaced with an internal pipe gripping assembly for gripping the internal surface of a section of pipe. Control fluid pressure is trapped within the actuator assembly, but relieved from a fluid swivel, permitting high speed rotation of the modular pipe gripping assembly and preserving swivel seal life.

Modular apparatus for assembling tubular goods

A mating connection assembly of the present invention permits quick and efficient connecting and disconnecting of tubular goods. A female box-end connection member has an inner body defining sockets; ball bearings held within such sockets with an outer sleeve. A male pin-end connection member is inserted within the box end connection. By moving the outer sleeve axially, the ball bearings are urged inward toward the male pin-end connection, creating a frictional locking relationship between the female box-end connection member and male pin-end connection member.

Connection assembly for tubular goods

A casing running tool capable of handling pipe and tubing has fluid power conducting channels leading from stationary to rotating components, through a swivel. The swivel has a plurality of fluid channels, each confined by dynamic seals that rub peripherally on mating seal surfaces. The seals are carried on at least one piston that is movable, on command, to carry the seals out of contact with the peripherally rubbing surfaces.

Fluid power conducting swivel

An arbor arranged for attachment to overhead support, such as a top drive or main rig hoist, is arranged to resiliently support a main body. The main body is arranged to support a wedge-lock type pipe gripper assembly on a second arbor that is resiliently supported by the main body. The two arbors are rotationally connected but only indirectly connected axially and, to a limited extent, can move independently. The actuator, or linear motor, that actuates the wedge-lock system has the ability to force release of the wedge-lock system when it has been set by massive pipe loads. The forced release actuation is independent of the load supporting features of the main body. Full range actuation of the main body linear motor will not actuate the wedge-lock release system.

Pipe handling apparatus

A floating shoulder ring is arranged to occupy the J-space between pin ends of coupled pipe sections. The length of the ring is arranged to allow the pipe connection to approach the specified torque for shoulderless connections before the ring begins to function as an abutment between the approaching pipe ends. The torque accepted by the ring limits the radial force imposed by tapered threads on both pipe and coupling. The ring is provided with modified threads on the outer surface to engage the inner threads of the coupling, in the J-space, to retain the ring in the coupling during handling in preparation for assembly into a pipe string. The modified threads yield axially when substantially forced. Threads that slip axially, non-destructively, and threads that deform under sufficient axial force are provided.
