A well tubular is hung within a casing through placement of the tubular in overlapping relationship with the casing. A spacer may be located therebetween. The tubular is expanded which in turn expands the spacer when used. The tubular is expanded beyond the yield point such that it or an intervening spacer engages the inside of the casing and stresses the casing within its elastic limits. The assembly then contracts to form a tight structural support between the tubulars and a high pressure seal against flow therebetween. A spacer having channels about either end with ductile sealing material therein is of an expanded metal material through cuts in the sheet. A hydraulic ram is employed with an expandable collet to draw the collet through the overlapping area of the liner and the casing. The collet extends within a shoulder at the end of its stroke such that it will be substantially released from the upper end of the liner. A method for placing a lateral liner includes expanding the liner to beyond its yield point within the hole through the casing. The stub of the liner positioned within the casing may then be drilled out such that completed lateral and main bores are achieved.
