Safety valve with provisions for powering an insert safety valve
First Claim
1. A method of operating a valve positioned in a subterranean well, the method comprising:
- installing a first electrical actuator in a flow passage extending longitudinally through the valve in the well; and
operating a closure assembly in response to electrical power being supplied to the first electrical actuator via at least one direct electrical connection between the first electrical actuator and the valve.

Abstract
A method of operating a valve can include installing an electrical actuator in a flow passage extending longitudinally through the valve, and operating a closure assembly in response to electrical power being supplied to the electrical actuator. An outer safety valve can include a closure assembly which selectively permits and prevents flow through a longitudinal flow passage, and at least one electrical connector which electrically connects to an insert safety valve positioned in the flow passage. A method of operating an outer safety valve in a subterranean well can include installing an insert safety valve in the safety valve, and operating the insert safety valve with electrical current flowing from the safety valve to the insert safety valve.

15. An outer safety valve, comprising:
-
a first electrical connector; and a closure assembly which selectively permits and prevents flow through a longitudinal flow passage, the longitudinal flow passage being configured to receive an insert safety valve having a second electrical connector, wherein the first electrical connector makes direct electrical contact with the second electrical connector when the insert safety valve is positioned in the longitudinal flow passage. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
