| abstract | A plug apparatus comprises a wedge, a sealing ring, and a slip. The wedge comprises an axial wedge bore. A seat is defined in the wedge bore. The seat is adapted to receive a ball. The wedge has a tapered outer surface which decreases in diameter from the upper to the lower extent of the tapered outer surface. The sealing ring is received around the tapered outer surface of the wedge. The sealing ring has an axial ring bore and is radially expandable. The slip comprises an axial slip bore having a tapered inner surface. The tapered inner surface decreases in diameter from the upper to the lower extent of the tapered inner surface. The inner surface is adapted to receive the wedge. The wedge is adapted for displacement from an unset position generally above the slip to a set position wherein the wedge is received in the slip bore. |
