ABSTRACT:
A method of completing a well which includes the installion of a gravel pack completion adjacent a formation in the well. A fluid-loss agent is flowed into the well to form a barrier to flow into and/out of the formation prior to the installation of the gravel pack. A screen is then lowered into the well and is positioned adjacent the formation. A gravel slurry which includes a removal agent is flowed into the well to deposit gravel. The removal agent contacts and dissolves or disintegrates the flow barrier to thereby open flow to the formation during the placement of the gravel.
