ABSTRACT:
A system for gravel packing a production radial tube terminating in an open drillhead in electrically conductive oil bearing formation. An elongate perforating tube having spaced ports with electrically conductive perimeters connected to an electrical power source is passed to the forward end of the radial tube. Then an electrolyte solution is passed through the hollow interior of the perforating tube and out the ports to be directed against the tube while current is supplied to form spaced perforations in the tube. Then the perforating tool is withdrawn.
