Patent abstract
A Christmas tree and a method of completing a well in a standard wellhead. The tree is presented as separately deployable upper and lower portions with the master valves contained in the lower portion so that they are located below the wellhead housing to lower the height of the tree while increasing well safety and integrity. The upper master valve is bi-directionally sealing to allow for pressure testing, removing the requirement for tubing hanger plugs.
