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.

Expandable liner hanger with robust slips for downhole conditions with high pressure conditions

Embodiments of a system, method, and apparatus for a liner hanger installed into a wellbore are disclosed herein. In one embodiment, an apparatus comprises a liner hanger to be positioned within a wellbore, wherein the liner hanger comprises, at least one spike to secure the liner hanger to a casing within the wellbore, wherein an outer diameter of the at least one spike includes a seal recess; and a seal object to be positioned in the seal recess to form a seal with the casing when the liner hanger is hanging on the casing.

Self-energizing seal for expandable liner hanger

A liner hanger system for use in a subterranean well is disclosed. The liner hanger system comprises a well casing and a liner hanger. The liner hanger comprises a spike extending in an annular ring around an outer perimeter of the liner hanger. The spike comprises an annular groove defined therein. The liner hanger further comprises an annular seal positioned at least partially within the annular groove. The liner hanger is expandable to transition between an initial state where the spike is not in contact with the well casing and an expanded state where the spike is in contact with the well casing. The spike and the annular seal are configured to seal an uphole well portion from a downhole well portion when the liner hanger is in the expanded state.
