Abstract: Apparatus and methods pertaining to an adapter mechanically connecting a wireless actuator to an SCSSV subassembly that includes an SCSSV. The adapter mechanically connects to the SCSSV subassembly so that the adapter is situated uphole of the SCSSV subassembly when set in a tubular of a wellbore. An actuating piston is carried by the adapter. The actuating piston transfers an opening force to the SCSSV in response to receipt by the adapter of pressurized fluid from the wireless actuator, thereby opening a flapper of the SCSSV.
