Abstract
A subsea completion for a well is presented that includes a tubing spool, a tubing hanger, a fluid coupling, an electrical coupling, a control system, a valve, and a production tree. The tubing spool includes a central bore, a side wall, and a fluid supply passage extending through the tubing spool. An electrical supply passage can also extend through the side wall of the tubing spool. The tubing hanger includes a fluid control passage. The tubing hanger can also include an electrical control passage. The control system includes a fluid control conduit to provide fluid to the tubing spool fluid supply passage from outside the tubing spool. The valve is connectable to the outside of the tubing spool to control fluid flow between the control system fluid conduit and the tubing spool fluid supply passage.
