With todays rig spread rate it is more important than ever to succeed with plugging operation. Industry average is a 40 – 60 % success rate in setting off bottom cement plugs, ie 2 plugs are required for each success. A loss of 2- 4 days for each failure is common.

By using the CST the success rate can be raised to the same level as setting the cement plug on bottom. The CST is made from aluminum and composites and fabricated in a way that it can be folded together as an umbrella inside the transport tube.
