Abstract: A landing adapter is used to softly land a tubing hanger in the bore of a production tree. The landing adapter makes initial contact so that the tubing hanger does not have to absorb the harsh impact. The landing adapter has a hydraulic sleeve that strokes axially relative to the tubing hanger. Initially, the sleeve is extended and locked when it is run into the well so that the landing adapter can be hard-landed in the bore. When the sleeve lands in the bore, the impact is absorbed by a landing adapter buffer, not by the tubing hanger. After the hanger with the landing adapter has landed in the bore, hydraulic fluid is bled off so that the tubing hanger gradually descends axially relative to the sleeve and the tree to the retracted position. The landing adapter buffer remains in the tree after the tubing hanger is landed in the bore.
