Abstract
The apparatus includes a gravel pack assembly comprising a gravel pack body and a crossover tool. The crossover tool comprises auxiliary flow chambers and channels around a casing packer and a crossover tool check valve. The gravel pack body and crossover tool are assembled coaxially as a cooperative unit by a threaded joint. The assembly is threadably attached to the bottom end of a tool string for selective placement within the wellbore. Set of the packer secures the gravel pack body to the well casing and seals the casing annulus around the gravel pack assembly. After setting the packer, the tool string is rotated to release the threaded assembly joint between the crossover tool and the gravel pack extension. The desired flow function is determined by selective axial positionment of the crossover tool within the gravel pack body. When the gravel pack is in place, the crossover tool is axially positioned to flush residual aggregate from the tool string bore. The gravel pack body is dedicated to the wellbore and the crossover tool withdrawn and replaced by a production tube.
