Abstract
A method and apparatus for use in a subterranean well. The apparatus typically includes a subterranean plug including a mandrel having an outer surface and a non-circular cross-section and a packing element arranged about the mandrel, the packing element having a non-cylindrical inner surface matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus is substantially non-metallic to facilitate quick drill-out of the plug. The apparatus is alternatively adaptable as a cement retainer.
