Abstract: A tubing pressure insensitive failsafe wireline retrievable safety valve including a tool housing, a flow tube disposed within the tool housing, an actuation piston disposed in the tool housing and operably connected to the flow tube, the actuation piston having an actuation pressure side and a relatively lower pressure chamber side, a fluid pathway between a potential leak site for the valve and the relatively lower pressure chamber side of the piston. A borehole system having a tubing pressure insensitive failsafe wireline retrievable safety valve. A tubing pressure insensitive failsafe wireline retrievable safety valve.

Abstract: A tubing pressure insensitive failsafe wireline retrievable safety valve, borehole system having the valve and method of operation of the valve. The valve includes a tool housing, a flow tube disposed within the tool housing, an actuation piston disposed in the tool housing and operably connected to the flow tube, the actuation piston having an actuation side and a pressure side, and a fluid pathway between a potential leak site for the valve and the pressure side of the piston. A temporary sealing member is in the fluid pathway between the potential leak site and the pressure side of the piston. The method includes disposing the valve at a selected location and removing at least a portion of the temporary sealing member from the fluid pathway after landing the wireline retrievable safety valve at the selected location.

Abstract: A downhole component includes a unitary body having a first end portion, a second end portion and an intermediate portion extending therebetween. The intermediate portion defines an outer surface and an inner surface forming a flow path. An annular chamber has a first end section spaced from a second end section by a gap. The annular chamber is formed in the unitary body spaced from the first end portion, the second end portion, the outer surface, and the inner surface.

Abstract: A downhole component has a body including a first end portion, a second end portion and an intermediate portion extending therebetween. The intermediate portion includes an outer surface and an inner surface. The inner surface defines a flow path. An axial passage extends radially outwardly of the flow path between the outer surface and the inner surface. A piston is arranged in the axial passage.
