Abstract
An expandable tubular having a receptacle at its lower end is installed in a wellbore. An axial force is generated on a solid cone assembly to push the solid cone assembly. The solid cone assembly includes a cone body formed from a drillable material, the cone body having an expansion surface, a first expansion profile formed in a first portion of the expansion surface, and a second expansion profile formed in a second portion of the expansion surface. The second expansion profile includes one or more facets. The facets of the second expansion profile engage the receptacle, providing a rotational lock to the cone body. After expansion of the expandable tubular, the cone body may be drilled or milled.
