## 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.

## Claims

### Claim 1

A method of hanging an inner tubular string from an outer tubular string cemented in a wellbore, comprising:
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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the command signal is sent by pumping a wireless identification tag through the deployment string and to the running tool.

### Claim 3 (depends on 1)

The method of claim 1:
further comprising reopening the bore after plugging,
wherein the tag is pumped after reopening the bore.

### Claim 4 (depends on 1)

The method of claim 1, wherein:
the running tool is unlocked by sending the command signal, and
the method further comprises releasing the running tool by rotating the deployment string.

### Claim 5 (depends on 4)

The method of claim 4, wherein the running tool is rotated while weight of the deployment string is set on the inner tubular string.

### Claim 6 (depends on 1)

The method of claim 1, wherein:
an actuator of the running tool is operated in response to receiving the command signal, and
the actuator disengages a longitudinal fastener of the running tool from the inner tubular string.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
pumping cement slurry into the deployment string; and
driving the cement slurry through the deployment string and deployment assembly into an annulus formed between the inner tubular string and the wellbore.
