Abstract

An expansion system is assembled by coupling a piston assembly and a solid cone assembly to an adjustable cone assembly within an expandable tubular having inner sleeve disposed in a portion thereof. The expansion system is run into a wellbore. The piston assembly is activated to move the solid cone assembly downward through the inner sleeve so as to expand the inner sleeve and the portion of the expandable tubular having the inner sleeve. The adjustable cone assembly is shifted from a retracted position to an expansion position within the inner sleeve. The adjustable cone assembly is moved upward through expandable tubular while leaving the solid cone assembly and the inner sleeve coupled to expandable tubular. The solid cone assembly and the inner sleeve may be drilled or milled.
