Inflatable External Casing Packer

Inflatable External Casing Packer with IntegraLOK Valve

The Inflatable External Casing Packer (ECP) is designed to be run as an integral component in the casing string or liner. Once inflated they provide permanent impermeable annular barriers between casing strings or between the casing and open hole. Inflatable packers seal in vertical, deviated, and irregular wellbores.Applications for ECPs include to support primary cement, isolate lower zones during multi-stage cementing, segregate production zones, isolate lost-circulation, gas or water zones and plug and abandonment.Every ECP features a fully continuous mandrel that forms part of the casing or liner and serves as the main support for the ECP Valve and Inflatable Packer Element components.ECPs are inflated by pressurizing the entire casing, or by straddling the inflation port.

Valve operation is not affected by unpredictable pressure changes below the element

Superior anchoring system prevents element rotation, and packer shoe travel, while tools are run into the well
