Safety valve including first, second and third connected portions

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 sliding sleeve, the first portion configured to be run-in-hole as part of the production tubing;
• 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, the second portion configured to be run-in-hole after the first portion;
• and
• a third portion, the third portion including a mechanical connecting apparatus, the third portion configured to be run-in-hole after the second portion, and further wherein the mechanical connecting apparatus is configured to couple with the sliding sleeve of the first portion and the bore flow management actuator of the second portion to axially fix together the sliding sleeve and at least a portion of the bore flow management actuator.

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 sliding sleeve;
• positioning a second portion within the wellbore after positioning the first 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, the second portion configured to be run-in-hole after the first portion;
• and
• positioning a third portion within the wellbore after positioning the second portion within the wellbore, the third portion including a mechanical connecting apparatus, wherein the mechanical connecting apparatus is configured to couple with the sliding sleeve of the first portion and the bore flow management actuator of the second portion to axially fix together the sliding sleeve and at least a portion of the bore flow management actuator.
