Abstract: A selectably operable passive gripping device for gripping tubular materials has an elastomeric element which is provided with integrally bonded segmented end rings to prevent the extrusion of the elastomer when it is subjected to high compressive loads. The elastomeric element is molded so that its as-molded gripping surface interferes with the surface of tubular objects to be gripped. The elastomeric gripping element is mounted and supported by a structural element or housing and allows axial flow communication through the gripped tubular objects. The gripping device is used to lift tubular objects such as a tubular string used in oil field applications.

Abstract: A drillstring combination pressure reducing and signaling valve assembly uses multiple ball valves mounted in parallel, each having a different bore, to meter the flow through a drillstring. The individual ball valves are maintained in either a fully open or a fully closed position, but can be selectively moved between these two positions. The bores of the individual ball valves are sized so that at a given pressure, a first ball valve has a predetermined flow rate, a second ball valve has twice the flow rate of the first ball valve, a third ball valve has twice the flow rate of the second ball valve, and the remaining ball valves each have twice the flow rate of their predecessor in the valve sequence. This arrangement permits the flow rate and flow pressure drop through the assembly of valves to be digitally controlled by varying the combination of open and closed valves. In addition, another ball valve serving as a signaling valve is rapidly shifted either between a closed position, an open position, and back to a closed position. The signaling valve serves as a bidirectional signaling valve by relaying sensed pressure pulse signals emanating from either above or below the signaling valve past the valve assembly. Alternatively, the additional ball valve can be rapidly shifted between an initial open position to a closed position and then to a final open position. Pressure sensing is provided both above and below the valve assembly, and operative and control means are provided for the valve assembly.

Abstract: A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, while the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs. Additionally, while the secondary spring is engaged, hydrodynamic damping of the ball opening movement is provided.

Abstract: A downhole drilling valve tool, positioned above the drill bit, which utilizes a ball valve having a through bore for normal flow. The ball valve is operated bidirectionally by a piston driven mechanism between an open position and a closed position. The piston mechanism is responsive to a reference accumulator pressure on a first side and the pressure in the apparatus bore above the ball valve on a second side. Whenever the valve apparatus is lowered at least a minimum distance into the well bore, a pressure relief valve is used to maintain a fixed margin between the flowing bore pressure and the accumulator pressure. Closure of the ball valve occurs when the accumulator pressure exceeds the bore pressure during pump stoppages. The downhole drilling valve tool offers a more wear resistant sealing means, as well as higher pressure operability than conventional downhole check valves.
