Abstract
Disclosed herein are embodiments of a fail-safe surface controlled electric subsurface safety valve for use in a well. For example, in one embodiment, an electric sub-surface safety valve (eSSSV) system is disclosed that includes a master control system; a subsea control module; and an electric sub-surface safety valve having dual, redundant electronic modules that are configured to control power to dual electromagnetic actuators that move a single valve.
Claims20
An electric sub-surface safety valve (eSSSV) system comprising:
- a master control system;
- a subsea control module;
- and
- an electric sub-surface safety valve comprising dual, redundant electronic modules consisting of a first downhole electronics unit and a second downhole electronics unit that are configured to control power to a first electromagnetic actuator and a second electromagnetic actuator that move a single valve;
- wherein at least one electronic module comprises a feed-through switch;
- wherein the switch enables the modules to either communicate independently or in tandem with the downhole electronics units.
