Abstract

A method of hanging an inner tubular string from an outer tubular string cemented in a wellbore includes running the inner tubular string and a deployment assembly into the wellbore using a deployment string, wherein a running tool of the deployment assembly longitudinally and torsionally fastens the liner string to the deployment string; plugging a bore of the deployment assembly; hanging the inner tubular string from the outer tubular string by pressurizing the plugged bore; and after hanging the inner tubular string, sending a command signal to the running tool, thereby unlocking or releasing the running tool.
