Abstract: Provided is a retrievable safety valve insert, a safety valve, a well system, and a method. The retrievable safety valve insert, in one aspect, includes an outer housing including an outer housing central bore extending axially therethrough, the outer housing central bore operable to convey subsurface production fluids there through. The insert, according to this aspect, may further include a lock mandrel having a lock mandrel profile extending radially outward from the outer housing, the lock mandrel profile movable between a radially retracted state and a radially expanded state configured to engage with an end sub profile of an end sub. The insert, according to this aspect, may further include a safety valve insert closure mechanism coupled to the outer housing proximate a downhole end of the outer housing central bore, the safety valve insert closure mechanism movable between an outer housing closed state and an outer housing open state.

Abstract: A tubing retrievable safety valve assembly and related methods are disclosed herein. The assembly includes a primary flapper, a secondary flapper, a flow tube, and a protective sleeve. The flow tube is shiftable between a downhole position that holds the primary flapper in an open position and an uphole position that allows the primary flapper to move to a closed position. The protective sleeve, when positioned in an uphole position, holds the secondary flapper valve in an open position. The protective sleeve is shiftable to a downhole position to allow the secondary flapper to move to a closed position, for example, upon failure of the primary flapper.

Abstract: A bypass diverter sub including a housing defining a flow passage, a control line bypass piston arranged within a control line bypass bore defined in a wall of the housing, and a balance line bypass piston arranged within a balance line bypass bore defined in the wall. An outer magnet is disposed within a magnet chamber and is operatively coupled to the control and balance line bypass. A flow tube profile is positioned within the flow passage and provides an inner magnet magnetically coupled to the outer. The flow tube profile is movable between a first position, where control line and balance line pressures circulate through the bypass diverter sub to a subsurface safety valve, and a second position, where the control line pressure is diverted into the flow passage and the balance line pressure is diverted into a balance line jumper conduit.
