ABSTRACT:
An improved well structure such as a well housing on which a casing hanger is to be landed which housing includes a high strength landing shoulder insert which allows the housing to support the casing hanger, its casing and the heavy loads associated therewith and with substantial pressure loads experienced in new wells. In one form of the invention an insert is provided in an internal recess in the housing and held therein by a housing ring threaded on the interior of the housing body. In another form an insert is introduced into an internal housing recess in the form of seat segments and bypass segments which are secured in place by the radial forming of a high strength seat ring. In still another form of the invention the high strength seat insert is segmented, positioned as segments in the internal housing recess and secured therein by the radial forming of a metal ring outwardly into internal recesses in each of the high strength seat insert segments. A casing hanger having a high strength landing ring carried thereon is landed on the high strength seat insert.
