Improve the probability of casings and liners reaching TD when rotation cannot be applied.

The NaviREAM is a casing reamer shoe that features an eccentric profiled nose. When inserted into the tool, the relative rotational motion from reciprocation can be used to orientate the nose over or past obstructions.
