Reliable sealing and adaptable deployment
The Welltec® HEX Plug 5.5 is a high-expansion, retrievable bridge plug engineered for deployment via wireline or slickline. Designed to pass through narrow wellbore restrictions and set securely in larger internal diameters, it provides a robust, rigless solution for zonal isolation, well integrity, and temporary or permanent barriers.
Its compact running OD — smaller than 3"— enables access through tight profiles where conventional plugs cannot pass, offering a distinct advantage over competitors. The plug is mechanically set, eliminating the need for explosives and enhancing operational safety and control. The HEX Plug is available in V0-rated configurations, qualified to ISO 14310 standards, ensuring gas-tight sealing performance for critical well integrity applications
