Cement Support Tool CST
Product Description
The Cement Support Tool (CST) is designed to be pumped through long work strings and when exiting, fills the open / cased hole to support the off-bottom cement plug.
Cement plugs are set in wells for a variety of reasons. Industry challenges has demonstrated that it is difficult to successfully set these cement plugs. The Cement Support Tool (CST) is designed to be pumped through the work string before it expands and creates a support for the cement plug to rest on.
Average failure rate is reported to be approximately 50 % when not using a firm support to set the cement plug on.
The CST will form this support and ensures that the cement plug is set with confidence. After the introduction of the CST in 2002, more than 4000 units has been run globally with a success rate above 95%.
