Abstract
A well system may include a tubing string positioned downhole in a wellbore defining an annulus between the tubing string and a wellbore. An annular safety valve may be positioned at the surface of the wellbore for controlling a passage of gas through the annular safety valve into the annulus. The annular safety valve may include an inductive coupler that is coupled to a power source at the surface via a power line for powering the annular safety valve.
