Abstract

An expansion cone assembly () for setting a liner hanger. The expansion cone assembly () includes a cone mandrel () having an outer frustoconical surface (), a lead cone () slidably disposed around the cone mandrel () having a frustoconical surface () with a maximum outer diameter () and a collapsible cone () slidably disposed at least partially around the outer frustoconical surface () of the cone mandrel (). In an expansion configuration, the outer frustoconical surface () radially props the collapsible cone () such that it has a first maximum outer diameter () that is greater than the maximum outer diameter () of the lead cone (). In a retrieval configuration, the collapsible cone () axially shifts relative to the outer frustoconical surface () such that it has a second maximum outer diameter () that is no more than the maximum outer diameter () of the lead cone ().
