Zusammenfassung:In general, in one aspect, embodiments relate to an expandable liner hanger that includes a body that includes one or more anchoring ridges configured to seal against a casing, where at least one of the one or more anchoring ridge includes a first section and a second section, where a first axial distance spanned by the first section is less than a second axial distance spanned by the second section, and where the second section is reinforced to resist differential pressure that reduces contact pressure between the first section and the casing.
