In one embodiment, a method of hanging a liner assembly from a previously installed tubular in a wellbore includes running the liner assembly and a setting tool into the wellbore using a run-in string. The setting tool includes an isolation valve and the liner assembly includes a liner hanger and a liner string. The method further includes sending an instruction signal from the surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates a setting pressure in the setting tool from the liner string; and increasing fluid pressure in the setting tool, thereby setting the liner hanger. ## Claims ### Claim 1 An expandable liner system for use in a wellbore, comprising: an expandable liner; and an expander assembly disposed in the expandable liner and comprising: a mandrel releasably connected to the expandable liner; a seal longitudinally coupled to the mandrel and engaged with an inner surface of the expandable liner; a two position expander disposed along the mandrel and having a plurality of first cone segments and a plurality of second cone segments movable between an expanded position and a retracted position; a hydraulic actuator in fluid communication with a bore of the mandrel and operable to move the two position expander from the retracted position to the expanded position; and a valve having a valve member for facilitating pressurization of the mandrel bore in a closed position, an actuator for closing the valve member, and an electronics package for operating the actuator in response to receiving an instruction signal via wireless telemetry, wherein: the wireless telemetry is radio frequency identification (RFID), and the electronics package comprises a receiver located adjacent to a bore of the mandrel for receiving the instruction signal from an RFID tag travelling through the bore. ### Claim 2 (depends on 1) The liner system of claim 1, wherein: the valve member is a sleeve for covering ports formed though a wall of the mandrel in the closed position, and the valve has a ball seat for receiving a ball having the RFID tag. ### Claim 3 (depends on 1) The liner system of claim 1, wherein: the expandable liner is part of a liner assembly further comprising a shoe coupled to the expandable liner, and the mandrel is releasably connected to the shoe by a threaded connection. ### Claim 4 (depends on 3) The liner system of claim 3, wherein the liner assembly further comprises a corrugated liner coupling the shoe to the expandable liner. ### Claim 5 (depends on 3) The liner system of claim 3, wherein: the shoe has a bore formed partially therethrough and radial port formed therethrough and in fluid communication with the bore, and the shoe has a sleeve disposed in the bore and longitudinally movable between an open position exposing the ports and a closed position covering the ports. ### Claim 6 (depends on 1) The liner system of claim 1, further comprising a hydraulic release mechanism in fluid communication with the mandrel bore and operable to move the two position expander from the expanded position to the retracted position. ### Claim 7 An expandable liner system for use in a wellbore, comprising: an expandable liner; and an expander assembly disposed in the expandable liner and comprising: a mandrel releasably connected to the expandable liner; a seal longitudinally coupled to the mandrel and engaged with an inner surface of the expandable liner; a two position expander disposed along the mandrel and having a plurality of first cone segments and a plurality of second cone segments movable between an expanded position and a retracted position; a hydraulic actuator in fluid communication with a bore of the mandrel and operable to move the two position expander from the retracted position to the expanded position; and a valve having a valve member for facilitating pressurization of the mandrel bore in a closed position, an actuator for closing the valve member, and an electronics package for operating the actuator in response to receiving an instruction signal via wireless telemetry, wherein: the wireless telemetry is radio frequency identification (RFID), the valve member is a sleeve for covering ports formed though a wall of the mandrel in the closed position, and the valve has a ball seat for receiving a ball having an RFID tag.
