Abstract
A zonal isolation apparatus for an open-hole wellbore completed with a gravel pack having sections of blank pipe intermediate selected sections of sand screen, comprising a blank liner, with a first packer and second packer disposed therein. The first and second packers are set adjacent to sections of blank pipe and seal an annular area formed between the blank liner and the surrounding sections of sand screen at the first and second sections of blank pipe. The flow of fluids into the wellbore intermediate the first and second sections of blank pipe is inhibited.
