Abstract
An adjustable hanger system secures a hanger to a wellhead such that a downward extending tubular may be tensioned at a selected level. The wellhead includes a housing having a plurality of axially spaced grooves, with selected grooves receiving a support member therein. The wellhead housing also has an axially elongate and generally cylindrical sealing surface spaced above the plurality of grooves for sealing engagement with a seal element. The hanger is axially movable relative to the plurality of grooves. The hanger is supported by the support member which is radially movable into selected ones of a plurality of grooves. A lockdown member may also move into selected ones of the plurality of grooves for preventing axially upward movement of the hanger relative to the wellhead.
