Abstract
A down-hole tool for pressure testing production tubing within a borehole of a well returning the well to production, includes an anti-rotational device comprising a tubular housing having a first end, a second end, an outer surface, and at least one anti-rotational wing disposed on the outer surface of the tubular housing, radially extendable to engage a radial surface of the borehole to anchor the production tubing thereto; a valve for controlling the flow of down-hole fluids within the production tubing, the valve comprising a first valve member fixedly positioned within the tubular housing of the anti-rotational device and a second valve member positionable between a closed position and an open position; and a reactivation device comprising means for axially engaging an axial surface of the borehole, the reactivation device affixed to the first end of the tubular housing, wherein the production tubing may be pressure tested when the valve is in the closed position.
