ABSTRACT:
A well completion method is provided wherein an inflatable packer is positioned in an open borehole of a well opposite a formation from which or into which a fluid is to flow. Cement is then forced into the packer to expand its packing element into contact with the wall of the borehole at the formation. The cement is allowed to set and then at least one perforation is made from the interior of the packer through the cement and packing element to the formation. A well system is also provided in which the well is equipped with such a packer so installed and having such a perforation.
