Beschreibung
Zusammenfassung:	A system for gravel packing a production radial tube terminating in an open drillhead in an oil bearing formation. The radial tube is perforated by an electrolytic perforation tool which is removed. A flexible permeable liner is passed into the radial tube and slurry is flowed through the liner and out the distal end to the radial tube back towards the well bore to the fill. Then, plug filters are placed at the proximal and distal ends of the radial tube which pass oil but not gravel, and the proximal end of the radial tube is severed, if desired.
