Abstract: A threaded connection for a conduit is disclosed. The connection includes a male member having threads on it defining a load flank lead (14), a stab flank lead (12) and a nominal lead (10). A female member has threads thereon adapted to mate with the threads on the male member. The threads on the female member define a load flank lead (14), a stab flank lead (12) and a nominal lead (10). At least one of the load flank lead (14) and the stab flank lead (12), on at least one of the female member and the male member, is changed at a predetermined rate beginning at a selected distance from an end of the threads. The load lead (4) and the stab lead (2) are different from each other over at least part of the thread length.

Abstract: A radially expandable tubular connection including a box member having an internal thread and a first seal surface and a pin member having an external thread and a second seal surface. The external thread threadedly engages the internal thread and the first and second seal surfaces form a metal-to-metal seal upon engagement of the seal surfaces. At least one groove is formed on an outer surface of the box member, and at least one groove is shaped so that the box member radially deforms in a direction toward the pin member in a region near the metal-to-metal seal after radial plastic expansion of the pin and box members after engagement of the threads.

Abstract: An extended lift coupling for joining tubular members in an end-to-end relationship is disclosed. The coupling is of simple design having only three components: a pin, a box and a threaded lock ring. An external compressive axial preload places a torus on the pin in axial compression. Make-up of the lock ring maintains the compressive strain on the torus and the lock ring when the axial make-up force is removed. Thereafter, increased tensile loading on the pin and box is partially absorbed in benign compressive stress of the locking ring. By controlling the geometry of the coupling such that the stiffness of the torus is high compared to the stiffness of the box and the stiffness of the lock ring, the fatigue life of the coupling caused by applied cyclic tensile forces is enhanced.

Abstract: A system adapted for alternative use as a diverter or a blowout preventer for a bottom supported rig and adapted for positioning beneath a rotary table of the drilling rig. The system comprises a fluid flow controller (10) and at least two bases (14a, 16a) adapted for being alternatively removably secured to the controller (10). When the first base (14a) is in combination with the fluid flow controller (10), the system may be used only as a diverter and when the second base (16a) is used in combination with the fluid flow controller (10), the system may be used only as a blowout preventer. A method according to the invention includes steps for installing the system adapted for alternative connection as a diverter or a blowout preventer for a bottom supported drilling rig after structural casing (20) has been set in a borehole (22).
