## Abstract

Rotating a casing during a cementing operation to ensure efficient displacement of cement slurry. More specifically, embodiments are directed towards a sub and rotating tool that are positioned above a first cement operation, wherein the rotating tool is positioned in a kickoff point or build section of a horizontal well.

## Claims

### Claim 1

A method for rotating casing in a well comprising:
executing a first job utilizing a first sub and a rotating tool;
executing a second job utilizing a second sub and the rotating tool, the second job being above the first job, wherein the rotating tool includes an inner housing, an outer housing, and a clutch positioned between the inner housing and the outer housing;
rotating the inner housing in a first direction without rotating the outer housing in the first direction; and
rotating the inner housing and the outer housing in the second direction together.

### Claim 2 (depends on 1)

The method of claim 1, wherein the second sub rotates while the first sub is stationary.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second sub and the first sub rotate simultaneously.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
radially expanding a packer between the first job and the second job to pressure test an integrity of the first job, wherein the first job is a cement job, and the rotating tool is positioned between the first sub and the second sub.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
pumping a first wiper plug downhole to expose a communication port in the second sub; and
pumping a second wiper plug downhole to close the communication port in the second sub.

### Claim 6 (depends on 5)

The method of claim 5, further comprising:
rotationally locking the rotating tool and the second sub after pumping the second wiper plug downhole.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
bursting a first burst disc associated with the first sub before executing the first job;
bursting a second burst disc associated with the second sub before executing the job, the second burst disc bursting at a higher pressure than the first burst disc.

### Claim 8 (depends on 1)

The method of claim 1, further comprising:
pressure testing the first job before executing the second job, wherein the first job and the second job are cement jobs.

### Claim 9 (depends on 8)

The method of claim 8, further comprising:
pressure testing the second job after executing the second job.

### Claim 10 (depends on 9)

The method of claim 9, wherein the pressure testing the second job is done at higher pressures than the first job.
