<p>A subsea hydrocarbon reserve is exploited by intially drilling a first well (4) from a floating drilling vessel (2). A tree (8) is then installed on the well (4) and a production riser (10) is established between the well and the vessel for transferring production fluid from the first well (4) to the vessel (2) from where an off-loading hose (12) conveys the production fluid to a tanker (18). Production fluid is then extracted from the first well (4) via the production riser (10) which is of sufficient flexibility and length to permit the drilling vessel (2) to move between appropriate locations to drill further wells (4', 20).</p> |
