ABSTRACT:
A wellhead plug assembly having one or more plugs for plugging segments of a wellhead bore through which access during completion and production procedures is gained. Each plug has a shortened length that is achieved by positioning connections between several of the components of the plug assembly radially beneath the anchoring and sealing means. By placing the connections radially inward to, and in tandem with, the sealing and or anchoring means, the overall length of a given plug may be shortened to less than eleven inches for plugs to be used in conduits having internal diameters greater than one and one-half inch. Furthermore, the tandem orientation allows plug designs in which a majority of the overall longitudinal length of the plug comprises the collective longitudinal lengths of the seal and anchor means.
