Casing running tools provide a mechanized, safe and cost-effective way to run and make-up casing. There are many benefits to adding a Casing Drive System™ (CDS™) to a drilling operation.
First, the purpose of every CDS™ model is to provide automation of running casing and ensuring that casing reaches bottom without fail. It has been proven that pipe rotation and reciprocation while cementing helps to achieve a more reliable and secure cement job. Canrig® casing running tools provide the ability to rotate, circulate, and reciprocate pipe simultaneously during cementing operations.
Oftentimes, casing running tools are only utilized in cases when pipe is stuck downhole. Canrig® CDS™ tools can certainly handle challenging situations such as stuck pipe; however, the CDS™ is built for more. It works with the top drive to easily attain smooth make up with no bending load and with precise control on final torque. Rig up a CDS™ from the beginning of any job and achieve the cost-saving and productivity yields throughout the casing or cementing processes.
Canrig® CDS™ also decreases the amount of equipment required onsite and enhances safety. A mechanized casing running tool replaces typical conventional equipment such as the power casing tong, casing elevators, spiders and a dedicated hydraulic power unit (HPU). This decreases manpower required, saves on equipment costs and provides a less cluttered — and safer — working environment. The CDS™ also eliminates the need to have a stabbing board operator working, which has been identified as a top factor that can cause lost-time incidents during operations.
