Document Type and Number:
WIPO Patent Application WO/2009/133542
Kind Code:
A3
Abstract:
Methods and apparatuses for the production of hydrocarbons from an offshore reservoir are disclosed. The hydrocarbons are produced using at least one spur (or flowline) (116), and at least one riser conduit (112,114) to transport said hydrocarbons from the seafloor to a point at or near the sea surface, wherein an artificial lift method, such as the injection of a lifting gas, is used to help transport said hydrocarbons from the reservoir to said point at or near the surface, and wherein said artificial lift method is applied to said hydrocarbons at a point (150) along the at least one riser conduit, substantially above said seafloor.
