isol8 Ltd

isol8 is the emerging market leader in zero emission seals, providing the highest integrity wellbore barriers for every stage of the well lifecycle to maximise client value and radically reduce costs. Bi-Sn (Bismuth tin BiSn) and Bi-Ag (Bismuth Silver BiAg) are commonly used eutectic alloys in downhole barrier applications. They offer a gas tight seal qualified to ISO 14310 V0 standard. isol8 has developed proprietary alloys for low, medium and high temperature wellbore applications. isol8 is the only company that creates a metallurgical bond with the casing/tubing which delivers a ten-fold increase in shear bond strength compared to unbonded alloys and cement. Designed by well engineers, for well engineers, isol8’s pioneering technology exploits the benefits of alloy as a sealing technology in downhole well applications; Low melt point ‘bonded-alloy barriers’ (both non-expanding and expanding alloys such as bismuth tin BiSn) and thermite based exothermic heaters to generate radial heat and, in some instances, the thermite is used as a structural platform on which the alloy can form a seal. isol8 have a full-scale test facility in Port Townsend USA, in which the team form, test and qualify barriers at simulated downhole pressures, temperatures and wellbore deviations.
