ABSTRACT:
A method and apparatus for installing a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then a well completion tool (e.g. a fluid-permeable liner) having an auger blade thereon is lowered and rotated into the present gravel without circulating fluid through the tool. Since the auger blade mechanically displaces the gravel upward as the tool is moved into the preset gravel, there is no need to flow fluid under pressure to "fluidize" the gravel as is required in prior completions of this type.
