Abstract

A method and system for constructing a subsea well in a subterranean formation is described. A tubular in a subsea well defines a main wellbore, and a fluid circulation path from the main wellbore to an outlet is formed via the wellbore annulus between the tubular and the subterranean formation. A cement slurry flows from the main wellbore along the wellbore annulus towards the outlet, causing fluid to be displaced from the annulus through the outlet. A controllable subsea choke in fluid communication with the fluid circulation path generates a backpressure in the fluid circulation path using the controllable subsea choke. In a preferred embodiment, the controllable subsea choke is part of a subsea pressure regulation system which also comprises a subsea pump.
