Abstract
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.
