Patent ID: 7909118

Claim:
A movable boring assembly for drilling a plurality of holes in a well casing and jetting a well production zone through said plurality of holes at a plurality of levels and in a plurality of directions comprising: a boring tool positioner that orients a drill tool to cut said plurality of holes in said plurality of directions in said well casing and orient a perforation jet in said plurality of holes to perforate said well production zone in said plurality of directions, said boring tool positioner comprising: a housing sleeve having a plurality of apertures distributed at different locations on said housing sleeve; a tool guide cylinder positioned rotatably in said housing sleeve that orients said drill tool and said perforation jet with said plurality of apertures; an angular positioner that controls rotational movement of said tool guide cylinder in said housing sleeve in a manner that causes a releasable, self-latching engagement between said tool guide cylinder and said housing sleeve to accurately and repeatably align said tool guide cylinder with said housing sleeve so that said drill tool and said perforation jet are accurately and repeatably aligned with said plurality of apertures; an antirotation mandrel coupled to a lower end of said boring tool positioner; a bow spring anchor that engages said antirotation mandrel to prevent said boring tool positioner from rotating; a releasable packer that releasably couples to said well casing; a packer mandrel that rotates in said releasable packer to orient said boring tool positioner in said plurality of directions to cut said plurality of holes in said well casing and to orient said perforation jet in said plurality of holes, and to vertically move said boring tool positioner to more than one level in said well to bore holes and perforate production zones through said holes in said well casing at more than one level.
