Deep-set insert valve using magnetic coupling

A tubing retrievable safety valve system, comprising:

• a downhole tubular having a central bore;
• a primary flapper valve disposed within the central bore and configured to actuate between an open position and closed position to control flow through the central bore;
• a control line extending axially through at least a portion of the downhole tubular;
• and
• at least one driver magnet configured to move axially along the control line between a first position and a second position, wherein the at least one driver magnet is configured to project a magnetic field into the central bore, wherein the magnetic field is configured to interface with at least one follower magnet of an insert valve to actuate an insert flapper of the insert valve between a closed position and an open position in response to movement of the at least one driver magnet between the first position and the second position, and wherein actuating the insert flapper between the closed position and the open position is configured to control flow through the central bore,
• wherein the at least one driver magnet includes an outer driver magnet and an inner driver magnet, wherein the outer driver magnet is configured to move axially along the control line between the first position and a second position and project a first magnetic field into the central bore, wherein the inner driver magnet is secured to a primary flow tube disposed within the central bore, wherein the inner driver magnet is configured to project a second magnetic field radially inward, and wherein the second magnetic field is configured to interface with the at least one follower magnet of the insert valve to actuate the insert flapper in response to movement of the outer driver magnet and the inner driver magnet.

• and
• an upper seal secured to an upper end of the at least one driver magnet and a lower seal secured to a lower end of the at least one driver magnet, and wherein the at least one driver magnet is fluidly connected to at least one drive piston configured to actuate to drive the at least one driver magnet toward the second position.

• a spring configured to bias the at least one driver magnet toward the first position;
• and
• a driver feature configured to actuate to drive the at least one driver magnet toward the second position, wherein the driver feature includes at least one drive piston disposed within the control line, and wherein the at least one drive piston is configured move axially along the control line in response to hydraulic pressure in the control line exceeding a threshold pressure.
