Apparatus and methods are provided for actuation of downhole tools. In one example, a deep set safety valve uses a magnetic coupling which permits a portion of the safety valve at control line pressure to be isolated from tubing string internal pressure, without requiring the use of a dynamic seal therebetween. A piston of the safety valve may be displaced in response to a differential between control line pressure and pressure in an annulus surrounding the tubing string, pressure in another control line, or pressure in the tubing string. Other types of ...


What is claimed is: 1. A method of actuating a safety valve, the method comprising the steps of: displacing an actuator member of the safety valve; translating displacement of the actuator member to displacement of an operating member, the translation being performed across a pressure isolation barrier without use of any dynamic seal; preventing flow longitudinally through the pressure isolation barrier when the operating member is in a closed position; and permitting flow longitudinally through the pressure isolation barrier when the operating member i...
