Abstract:
For completing a well, and for performing workover or intervention operations with the well, a surface BOP stack is coupled to the subsea wellhead or a subsea tree via a high pressure riser. The well is completed or the workover or intervention operations are performed through the surface BOP stack.

Claim (Index 1):
A method for constructing and completing a well comprising:\n coupling a conventional BOP stack to a subsea wellhead via a conventional riser; drilling and casing a wellbore through the conventional BOP stack and conventional riser; removing the conventional BOP stack from the subsea wellhead; coupling a mudline closure device to the subsea wellhead; coupling a high pressure riser to the mudline closure device; coupling a surface BOP stack to the high pressure riser; and completing the well through the surface BOP stack, wherein completing the well is performed using a landing string landing string coupled to a tubing hanger and a tubing, and without a subsea test tree.
