The Cement Support Tool (CST)
The Cement Support Tool (CST)
Designed to be pumped through long work strings, the CST effectively exits and fills the open or cased hole, ensuring robust support for the off-bottom cement plug. This design simplifies the cementing process, making it more efficient and reliable.
The CST is available in five standard sizes, with an additional customized version specifically for coiled tubing. This variety ensures that you can select the perfect size for your specific cementing needs, maximizing the effectiveness and reliability of your operations.
Choosing the right CST size is straightforward and depends on two key factors:
-
The inner diameter of your work string
-
The inner diameter of the open or cased hole where the cement plug will be set
