Abstract
Certain aspects and features are directed to an electric subsurface safety valve including an integrated communications system that can be disposed in a wellbore. The electric subsurface safety valve can include a body adapted to be coupled to a cable, a communications system disposed in the body, and a closure mechanism. The body can be disposed within the wellbore. The communications system can include one or more transceiving devices and a processing device. The transceiving devices can communicate signals via the cable to a rig at the surface and can wirelessly communicate signals to target tool in the well system. The processing device can process signals received by the one or more transceiving devices for communication via the cable. The closure mechanism can be positioned in a passageway defined by the wellbore and can control a flow of fluid to through the passageway.
