The Annular Casing Packer can be run in vertical, deviated or irregular wellbores for isolating lower zones during multi-stage cementing or to isolate lost-circulation zones in cased or open hole. The casing packer element is inflated after installation by pressurizing the entire casing or by straddling the inflation port.
The Casing Packer features a fully continuous mandrel that forms part of the casing or liner and serves as the main support for the Casing Packer Valve and Inflatable Packer Element components.
• Constructed on a continuous joint of casing to eliminate hidden internal connections

• Redundant inflation valve seals
• Packer element lengths ranging from 3 - 10 ft (0.91 – 3.05 m)
• Wide range of casing pup joint grade, weight and threads
