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. ## Claims ### Claim 1 A solid cone assembly comprising: a solid cone body having an expansion surface, wherein the expansion surface gradually increases in outer diameter from a leading edge to a maximum expansion diameter; a first expansion profile formed in a first portion of the expansion surface, wherein the first expansion profile has a circular cross section; either a second expansion profile formed in a second portion of the expansion surface, wherein the second expansion profile includes one or more facets, or a castellation included in the solid cone body; and a locking member coupled to an outer surface of the solid cone body, wherein the locking member includes a biasing member that urges the locking member outward. ### Claim 2 (depends on 1) The solid cone assembly of claim 1, further comprising a seal member coupled to an outer surface of the solid cone body. ### Claim 3 (depends on 2) The solid cone assembly of claim 2, wherein the seal member includes a downward-facing cup seal and an upward-facing cup seal. ### Claim 4 (depends on 2) The solid cone assembly of claim 2, further comprising a bore disposed in the solid cone body. ### Claim 5 (depends on 4) The solid cone assembly of claim 4, further comprising a seal seat formed in the bore. ### Claim 6 (depends on 4) The solid cone assembly of claim 4, further comprising a flapper valve and shear tube disposed in the bore. ### Claim 7 (depends on 1) The solid cone assembly of claim 1, further comprising a plurality of longitudinal slots formed in a portion of the solid cone body. ### Claim 8 (depends on 7) The solid cone assembly of claim 7, wherein the solid cone body is formed from a drillable material. ### Claim 9 (depends on 1) The solid cone assembly of claim 1, wherein either the second portion having the second expansion profile formed thereon is located between the leading edge of the expansion surface and the first portion having the first expansion profile formed thereon or the castellation of the solid cone body is located below the leading edge of the expansion surface of the solid cone body. ### Claim 10 A method of installing an expandable tubular comprising: locking a receptacle to a lower end of the expandable tubular, wherein the receptacle comprises an inner sleeve extending from a lower end of the expandable tubular upward in the expandable tubular; generating an axial force on a solid cone assembly including a solid cone body formed from a drillable material, the solid cone body having an expansion surface, wherein the expansion surface gradually increases in outer diameter from a leading edge to a maximum expansion diameter, a first expansion profile formed in a first portion of the expansion surface, wherein the first expansion profile has a circular cross section, and either a second expansion profile formed in a second portion of the expansion surface, wherein the second expansion profile includes one or more facets, or a castellation included in the solid cone body; pushing the solid cone assembly downward; engaging the receptacle either with the facets of the second expansion profile or with the castellation of the solid cone body; and drilling an upper part of the solid cone body. ### Claim 11 (depends on 10) The method of claim 10 further comprising engaging a lower shoe of the expandable tubular with locking members coupled to an outer surface of the solid cone body, wherein the locking members include biasing members that urge the locking members outward. ### Claim 12 (depends on 10) The method of claim 10 further comprising disintegrating a lower part of the solid cone body in small debris separated by a plurality of longitudinal slots formed in a portion of the solid cone body. ### Claim 13 (depends on 10) The method of claim 10 wherein the receptacle is formed to have either an inner profile with flat sections that correspond to the facets of the second expansion profile, or a castellation with faces corresponding to faces of the castellation of the solid cone body. ### Claim 14 (depends on 13) The method of claim 13 wherein either engaging the receptacle with the facets of the second expansion profile comprises engaging the flat sections of the receptacle with the facets of the second expansion profile, or engaging the receptacle with the castellation of the solid cone body comprises engaging the faces of the castellation of the receptacle with the faces of the castellation of the solid cone body.
