ABSTRACT:
An apparatus and method, particularly useful for isolating zones in a hydrocarbon wellbore. The apparatus includes a tubular section, such as a length of casing or liner tubular, arranged to be run into and secured within the wellbore which may be open hole or already cased. At least one sleeve member is positioned on the exterior of the tubular section and is sealed thereto. A pressure control device, which typically consists of a pressurised hydraulic fluid delivery device, can be used to increase the pressure within the sleeve member to cause the sleeve member to move outwardly and bear against an inner wall of the wellbore.
