Abstract
A multiple gravel pack well completion and a method for installing same wherein multiple zones in a wellbore can be gravel packed without the circulation of fluid. Particulate material, e.g. gravel, is preset in the wellbore adjacent the lower zone to be completed and a first auger-liner is 'augered' into the preset gravel to form a lower gravel pack completion. A packer is set above the lower zone abd additional gravel placed onto the packer to fill the wellbore adjacent the upper zone. A second auger-liner assembly is augered into the additional gravel to form an upper gravel pack completion. Conduit means are then provided to establish fluid communication between the surface of the wellbore and the upper and lower gravel pack completions.
