When used to eliminate Sustained Casing Pressure (SCP), TAM’s Casing Annulus Packer (CAP) is far more reliable than any chemical solution. Without a secondary barrier, cement integrity and zonal isolation problems are common when fluids travel upwards through the prior cement stage. With its over 99% success rate in elimination of gas migration, the CAP has established a worldwide reputation as a means to stop gas migration problems and eliminate SCP.
