Abstract:
A zone isolation apparatus for use in completing a wellbore comprising:a sand screen assembly disposed within the wellbore and comprising a packer element; a tubular string disposed within the wellbore defining an annulus area therebetween; an isolation assembly movable within the sand screen assembly and capable of being selectively positioned in an open configuration and a closed configuration; and a test assembly attached to the tubular string and capable of being selectively positioned in an open configuration and a closed configuration, whereby when the isolation assembly is in its closed configuration, fluid communication through the sand screen assembly is restricted, whereby when the test assembly is in its open configuration, hydraulic communication of the isolation assembly with the surface is achieved, wherein when the isolation assembly is in its closed configuration and the test assembly is in its open configuration, hydraulic communication between the annulus area above the packer and the interior of the isolation assembly is achieved, while providing hydraulic isolation from the annulus area below the packer.
