ABSTRACT:
An assembly for installation within the end of a joint of casing or liner for use in a downhole environment where the casing or liner is disposed in the borehole which traverses earth formations. The assembly includes an annular split ring expander and an annular split ring slip element and a self-energizing packing element which has an interference fit with respect to the bore of a string of pipe. A mechanically operated setting tool has a set of nut members on a threaded mandrel which are selectively operated for setting the slip element of the assembly into a wedging engagement with the expander in the wall of a well pipe and for releasing the setting tool from the body of the assembly to leave the assembly installed within the end of a joint of casing or liner.
