Abstract
A positioning tool is combined with a completion tool, for example a sand screen, for positioning the completion tool substantially within the lower half of a horizontal well casing member, and for automatically orienting the working face of the completion tool with respect to a predetermined sidewall portion of the well casing member. The orienting tool includes an annular roll collar which supports the completion tool off of the bottom of the horizontal well casing member, and a pair of radially projecting orienting vanes which limit rolling movement by engaging the upper bore of the well casing member.
