Xmas Tree Overview
Provides a pressure containing method to safely cap the Well via its interface with the subsea Wellhead
Xmas Tree features:• Control, monitor and condition either produced or injected media.
(Designs for either 5000, 10000 or 15,000 psi wp)• Provides normal and failsafe methods of shutting the Well at the mudline• Provides a interface to re-enter the Well at any time during the life of the
field• Provides a platform/interface from which to monitor down hole pressure
temperature or ‘smart well’ systems & applications • Provides a platform/interface from which to inject chemicals either down
hole or at the Xmas Tree
