The offshore Captain Field was discovered in 1977 in the UK sector of the North Sea, it was brought online in 1997 and initially developed using field-wide waterflood using long horizontal wells and artificial lift with produced water re-injection. The reservoirs are large and homogeneous sandstone reservoirs with high porosity and permeability, and around one billion barrels of medium to high viscosity oil at 18-21° API gravity. figure 1 (a) below shows the Captain offshore facilities, with the Wellhead Protection Platform (WPP) and the Bridge-Linked Platform (BLP). The map figure 1 (b) below shows the UK sector of the North Sea, with the Captain location highlighted.
