Reduce risks normally associated with casing running by adding a Casing Drive System™ to your operations and ensure that your casing gets to bottom safely and efficiently.
Tesco’s Casing Drive System™ (CDS™) is an adaptive and powerful casing running tool that serves many uses throughout casing operations. Whether the tool is used for an entire run, used for making up connections, as a fill-up tool, reaming casing, or just on stand-by in case of stuck pipe, the CDS can benefit any casing operation.
The CDS reduces the manpower needed on the rig floor and in the derrick by replacing conventional equipment, such as the manual single joint elevator, and by utilizing its integrated link-tilt system which incorporates extendable bails and hydraulic single joint elevators. This enables casing to be picked up at the V-door. An internal CDS tool applies grapples to the inside of casing to make up connections, and the external tool applies dies to the outside of the casing. The link-tilt system then positions the casing joint over the hole and supports the casing while lowering the CDS and top drive, eliminating the need unnecessary manual pipe-handling on the rig floor.
Once the connection is made up, circulation can be initiated, and the CDS may manipulate the entire string of casing. When used with a slip/spider assembly, the CDS interlock eliminates the chance of dropping the string in the well bore by preventing the CDS from releasing the pipe until the slips are set.
The CDS is designed with packer cups which allow it to be utilized as a fill-up tool until it is necessary to rotate the casing to bottom. This eliminates the danger of rigging up stabbing boards and having stabbers in the derrick and also saves time.
