TI Disk™

About This Product

The WOS Tubing Isolation (TI) Disk is a downhole device that allows for tubing solation from down hole pressures while tripping in hole. The TI disk can be activated with either impact or pressure by overbalancing the bottom hole pressure. The assembly utilizes a low overbalance pressure activation to avoid high tubing pressures. The TI Disk is available as a single barrier sub, a dual opposing barrier sub or can be set up to be used as a double barrier with two disks utilized in the same direction. Assemblies are also available in a variety of mule shoe, box and pin connections with 10,000psi and 15,000psi pressure ratings.
