ABSTRACT:
A polycentric reamer having a body thrust unit and reaming unit is especially useful for locally reaming a borehole beneath a casing string. By asymmetrically positioning a reaming unit within a body formed from non-coaxial mated cylinders, superior results are achieved. These results include minimizing wear on the casing string.
