ABSTRACT:
A method and apparatus for completing a lateral channel from an existing oil or gas well includes a well perforating tool for perforating a well casing at a preselected depth, and a lateral alignment tool for directing a flexible hose and blaster nozzle through a previously made perforation in the casing to complete the lateral channel. The disclosed apparatus eliminates the need to maintain the precise alignment of a downhole “shoe” in order to direct the flexible hose and blaster nozzle through a previously made perforation through the well casing.
