ABSTRACT:
A subsea wellhead assembly includes a wellhead housing, a production tree, a tubing hanger adapted to land in the wellhead assembly inside the wellhead housing without a need for angular orientation, a bridge member on the tubing hanger in the production tree, a port radially formed through the tubing hanger or the bridge member, a production port radially through the tree head housing, and an annular production flow passage that circumscribes the bridge member lower portion on one end and optionally circumscribes the tubing hanger on its other end. The annular production flow passage is in communication with both the production port and the radial port in the tubing hanger or bridge member so that fluid can be produced from the well via the annular production flow passage without necessity to orientate the tubing hanger.
