Seal Through Casing – STC

BiSN's Wel-lok™ PRT (Packer Repair Tool) seals multiple annuli in a single run by creating a new seal in the production by casing annulus. Sealing a production annulus with a PRT™ eliminates the need to remove a production string from a well to replace the packer, reducing operator costs and downtime while introducing a superior seal in the well.
