Abstract
A nested tubing hanger has a wellhead housing that defines a wellhead bore, an outer hanger installed within the wellhead bore of the wellhead housing that has a parent bowl that supports an inner hanger. A hanger engagement carried by the outer hanger is radially moveable between a release position and an engagement position. In the engagement position, the hanger engagement engages an engagement profile on an outer surface of the inner hanger to lock the inner hanger in the outer hanger. With the hanger engagement in a release position, the inner hanger is removable from the outer hanger.
