wel-lok™ Casing Leak Seal (CLS)

BiSN overcome the shortcomings of traditional methods of sealing tubing and casing leaks. Designed with flexibility in mind, the system can be used to isolate a small leak with a single seal or run as a straddle assembly to isolate larger intervals. The through-bore configuration allows for production to continue during the well intervention as well as providing access for wireline tools to be run. Alternatively, it can be milled out to achieve a full drift without compromising the integrity of the gas-tight seal.
