Gravel packing system for a production radial tube
Patent
·
OSTI ID:5797442
This patent describes a method of forming spaced perforations in an electrically conductive production radial tube extending from a well bore in an underground formation. It comprises passing an elongate hollow perforating tool, having a forward end and a rearward end and defining a lumen, through the electrically conductive production radial tube having a distal end and a proximal end to be perforated until the forward end of the perforating tool is adjacent the distal end of the radial tube, passing an electrolyte solution through the lumen of the perforating tool and out the ports to be directed against adjacent regions of the electrically conductive radial tube while current is supplied to the port perimeters to form spaced perforations at the adjacent regions, and withdrawing the perforating tool.
