摘要

A method and apparatus (Fig.1) for use in a subterranean well described. The apparatus typically includes a subterranean plug including a mandrel having an outer surface and a non-circular cross-section and a packing element arrange d about the mandrel, the packing element having a non-cylindrical inner surfac e matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus may include slip s having cavities to facilitate quick drill-out of the plug.
