Horizontal TreesAllows complete access to the well bore without removing the treeWell is produced from the side of the tubing hanger and flows horizontally through the master valveEconomical when used on natural flow wells, as a conventional riser / workover system is not requiredInternal tree cap and tubing hanger have the same seal design, setting technique, and running tool.All ROV access points are grouped on one side of the tree.Conventional workover/completion riser system not required for subsea HT horizontal tree, resulting in substantial savings.
