ABSTRACT:
A method and apparatus for increasing the diameter of a well bore in a cavern well completion after a drill pipe has been removed from the well bore and a drill bit has been removed from the drill pipe in which a reaming tool is formed with one or more cutters of a length in excess of the radius of the previous well bore, the cutters being attached by a pin to a coupling at the lower end of the drill pipe, the cutters being in the form of flat cutter blades which are capable of moving from overlapping relation to one another into diametrically opposed perpendicular relation to the rotational axis of the drill pipe and coupling when the drill pipe is rotated. The rotating drill pipe can be raised or lowered to lengthen the enlarged well bore to form an increased surface area of pressurized formation which is open to communicate with the less pressurized interior of the well bore and thereby substantially increase production flow rates.
