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.
