Abstract
A subsurface safety valve includes an outer housing, a flapper valve disposed within the outer housing, and a motor that pivotally displaces the flapper valve. The subsurface safety valve also includes a battery that powers the motor, a turbine that charges the battery and a wireless receiver that, responsive to a received signal, transmits a signal to the motor to pivotally displace the flapper valve. A related method includes: providing a subsurface safety valve having an outer housing; disposing a flapper valve within the outer housing; providing a motor, a battery, a turbine and a wireless receiver; charging the battery with the turbine; powering the motor with the battery; receiving a signal at the wireless receiver; and responsive to the received signal, transmitting a signal to the motor to pivotally displace the flapper valve.
