Abstract
A christmas tree to control the production from a subsea oil or gas well is disclosed. The christmas tree design including a tree body having a first flow port and a tree cap; a tubing hanger landed within the tree body; an actuation mandrel landed within the tree body, the actuation mandrel having a flow port; and a flow diverter disposed within the tree cap to divert flow through the flow port. The christmas tree arrangement allows for dual barriers within the tree cap without placing or retrieving any plugs from within the tubing hanger, thereby reducing the number of downhole trips required to complete and/or service the subsea well.
