Welcome to BiSN Performance Barrier Technologies!

BiSN’s Wel-lok technology is a metal-to-metal downhole sealing solution developed to provide a permanent seal through a thermite heat ignition and a rapid solidification process of eutectic bismuth alloy. The use of bismuth alloy is advantageous because once it is heated, the metal liquifies and is equal to that of the viscosity of water. The liquid bismuth alloy can then filter through porous locations prior to solidification, as opposed to conventional methods such as cement or resin.
