Abstract
An apparatus () and method, particularly useful for isolating zones in a hydrocarbon open hole well bore (). The apparatus includes a tubular body (), arranged to be run into and secured within the well bore. A sleeve member () is positioned on the exterior of the body and is sealed thereto creating a chamber () therebetween. Pressure is applied through a port () in the body to cause the sleeve member to move outwardly and morph to an inner wall of the well bore. Pressure is trapped in the chamber and maintained at a morphed pressure value by pressure balancing means in the form of a biased piston ().
