Patent ID: 8286717

Claim:
A method of hanging a liner assembly from a previously installed tubular in a wellbore, comprising: running the liner assembly, a wiper assembly, and a setting tool into the wellbore using a run-in string, wherein the setting tool comprises an isolation valve and the liner assembly comprises an expandable liner hanger and a liner string; pumping cement slurry into the run-in string; pumping a top plug through the run-in string, thereby driving the cement slurry through the setting tool and into the liner string, wherein: the top plug engages the wiper assembly and releases the wiper assembly from the setting tool, and the top plug and engaged wiper assembly drive the cement slurry through the liner string and into an annulus formed between the liner assembly and the wellbore; during or after pumping the cement slurry, sending an instruction signal from surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates the setting tool from the liner string; and after closing the isolation valve, increasing fluid pressure in the run-in string and setting tool, thereby expanding the liner hanger into engagement with the tubular.
