Retrievable bridge plug
The THOR™ High-Expansion Plug is a retrievable bridge plug designed for wireline, slickline, or coiled tubing deployment. Featuring an ultra-slim running OD, THOR passes easily through narrow wellbore restrictions before anchoring securely in larger casing or tubing – including open hole – where it is mechanically set to establish reliable reservoir isolation.
The THOR series includes
Available in ISO 14310 V0/V3-rated configurations, the plugs provide gas-tight sealing performance for critical barrier applications.
