Electromagnetic attraction on the flow sleeve of TRSVS

A well system, comprising:

• a wellbore extending through one or more subterranean formations;
• production tubing disposed in the wellbore;
• a subsurface safety valve (SSSV) disposed in line with the production tubing, the subsurface safety valve (SSSV) including:
• an outer housing including a central bore extending axially through the outer housing, the central bore operable to convey subsurface production fluids there through, wherein the outer housing includes cross-matched bores, a first bore of which extends from an outer surface of the outer housing toward a first location and a second bore of which extends from the central bore thereby crossing the first bore;
• a valve closure mechanism coupled to the outer housing within the central bore;
• a bore flow management actuator disposed in the central bore, the bore flow management actuator configured to slide from a first state to a second state to move the valve closure mechanism between a closed state and an open state;
• an electromagnet positioned at
• the first location, the first location in the outer housing proximate where a downhole end of the bore flow management actuator resides when the bore flow management actuator is in the second state;
• an electric line coupled to the electromagnet, the electric line configured to provide electric current to the electromagnet, and further wherein the electromagnet is located in the first bore and the electric line extends through the second bore to couple to the electromagnet;
• a primary control system on a primary control circuit coupled to the bore flow management actuator, the primary control system configured to slide the bore flow management actuator from the first state to the second state;
• and
• a safety control system on a safety control circuit, separate from the primary control system on the primary control circuit, coupled to the electromagnet, the safety control circuit and electromagnet configured to keep the bore flow management actuator at the second state when the electromagnet is energized and the primary control circuit is inoperable.
