摘要： A safety valve with a flapper/flow tube friction reducer. A safety valve for use in a subterranean well includes a closure assembly, an operating member which engages the closure assembly, and at least one of the closure assembly and the operating member including a friction reducing device which provides rolling contact between the closure assembly and the operating member. Another safety valve includes a flapper which rotates about a pivot relative to a seat, a flow tube which engages the flapper to rotate the flapper, and a friction reducing device which with rolling contact biases the flow tube toward the pivot when the flow tube engages the flapper. Yet another safety valve is described in which at least one of the flapper, the seat and the flow tube has a friction reducing device attached thereto which provides rolling contact between the flapper and the flow tube, or between the flow tube and the seat.

摘要： Hybrid-tieback seal assemblies, interventionless setting assemblies, and associated methods of setting downhole components of the hybrid-tieback seal assemblies using such interventionless setting assemblies are disclosed. A hybrid-tieback seal assembly comprises one or more anchoring bodies, one or more packer seal assemblies, and one or more interventionless hydraulic setting systems. A method of setting downhole equipment comprises applying a pressure to a compensating volume and providing a working volume, wherein the working volume is separated from the compensating volume by one or more hydraulic control devices. A pressure is applied to the working volume in response to the pressure applied to the compensating volume. The pressure applied to the compensating volume is then reduced and the pressure applied to the working volume is captured by the hydraulic control devices. The captured pressure in the working volume is applied to set one or more of the anchoring bodies and packer seal assemblies.

摘要： A flow control assembly can be mechanically adjusted, rotationally or translationally, inside a tubing downhole between multiple positions by an intervening tool from the surface to change resistivity to flow through the flow control assembly. The positions among which the flow control assembly can be adjusted can include a closed position, a fully open position, and positions at which fluid experiences various resistances prior to flowing to an inner area of the tubing.
