Applications of the CST world-wide

Perigon CST Applications World Wide


"Using Perigon's Cement Support Tool (CST) has increased the success rate to 100 % when setting balanced P&A plugs and balanced kick off plugs for Total E&P in Norway. The CST has been widely used both in open hole and cased hole applications. It has also recently been used to set cement plugs to combat subsurface losses."
