Abstract
An isolation system employing a containment zone within the casing or tubing of a wellbore. The containment zone can be isolated from the wellbore pressure and leak tested to ensure no leakage is occurring across the zone. The isolation system prevents wellbore pressure below the system from communicating with the surface, thereby allowing for safe egress of tools from within the wellbore.
