A method and apparatus for use in a subterranean well is 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 arranged about the mandrel, the packing element having a non-circular inner surface matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus may include slips having cavities to facilitate quick drill-out of the plug. The apparatus may include a valve for controlling fluid flow through a hollow mandrel. The apparatus may include a composite mandrel having radial vents that establish fluid communication from within to without the mandrel. Also, the apparatus may include a wire line adapter kit for running the apparatus in a well bore. |
