Safety valve employing radially coupled magnetic targets and an electromagnet axially coupled to a magnetic target

A well system, comprising:

• a wellbore extending through one or more subterranean formations;
• production tubing disposed in the wellbore;
• and
• a safety valve disposed in the wellbore, the safety valve including:
• a first portion, the first portion including a safety valve sub having a pocket therein, the pocket including an electromagnetic assembly, one or more radial outer magnetic targets, and a magnetic target located therein;
• a second portion, the second portion including a valve closure mechanism and a bore flow management actuator, the bore flow management actuator configured to slide from a first initial state to a first subsequent state to move the valve closure mechanism between a first closed state and a first open state;
• and
• a third portion, the third portion including a mechanical connecting apparatus having one or more radial inner magnetic targets associated therewith and configured to magnetically engage with the one or more radial outer magnetic targets, wherein at least one of the one or more radial inner magnetic targets or the one or more radial inner magnetic targets are one or more permanent magnets, the third portion configured to engage with at least a portion of the bore flow management actuator such that when the bore flow management actuator moves to the first subsequent state the magnetic target moves proximate the electromagnetic assembly, and further wherein when the magnetic target is located proximate an energized electromagnetic assembly the bore flow management actuator is fixed in the first subsequent state.

A method, comprising:

• positioning a first portion within a wellbore extending through one or more subterranean formations, the first portion including a safety valve sub having a pocket therein, the pocket including an electromagnetic assembly, one or more radial outer magnetic targets, and a magnetic target located therein;
• positioning a second portion within the wellbore, the second portion including a valve closure mechanism and a bore flow management actuator, the bore flow management actuator configured to slide from a first initial state to a first subsequent state to move the valve closure mechanism between a first closed state and a first open state;
• and
• positioning a third portion within the wellbore, the third portion including a mechanical connecting apparatus having one or more radial inner magnetic targets associated therewith and configured to magnetically engage with the one or more radial outer magnetic targets, wherein at least one of the one or more radial inner magnetic targets or the one or more radial inner magnetic targets are one or more permanent magnets, the third portion configured to engage with at least a portion of the bore flow management actuator such that when the bore flow management actuator moves to the first subsequent state the magnetic target moves proximate the electromagnetic assembly, and further wherein when the magnetic target is located proximate an energized electromagnetic assembly the bore flow management actuator is fixed in the first subsequent state.
