Anti-rotation apparatus for limiting rotation of cementing plugs

The present invention relates generally to drilling and completion techniques for downhole wells, and more particularly to methods and apparatus for limiting the rotation of cementing plugs being drilled out of the plugs. An apparatus for preventing or limiting the rotation of cementing plugs in a casing string during drillout. The apparatus includes an outer housing with a sleeve disposed therein. The sleeve has an inner surface configured to engage cementing plugs received therein to cause an interference fit. The sleeve will hold the cementing plugs when rotational forces, such as drilling forces, are applied so that during drillout, rotation of the cementing plug is prevented or is at least limited.
