The discovery well Agbami-1 was completed back in January 1999, from that well data it discovered 420ft of net pay. In a variety of zones ranging from 8,000-12,000ft. The well had encountered reservoir sand saturated with oil, with an overall column thickness of 400-1000ft. Confirmation of the size of Agbami-2 was conducted by the drill ship Glomar Explorer in 2000 which drilled through a water depth of 4800 ft and a total of 15,600 ft. The well encountered 534ft of net pay in a variety of zones.
Field Development And Subsea
For the project to maintain an optimum output, resevoire pressure must also be maintained. Due to the depth of the field and its location the most efficient course of action was to use injectors. Along with the producing wells that are tied to the FPSO via flow lines are gas and water injectors. These injectors are in place to maintain and extend the plateau output before the inevitable decline of the field.
- Total Liquids (BLPD): 450,000

The contract for the construction of the FPSO was won by South Korea firm Daewoo shipping and Marine Engineering in 2005. The FPSO was completed and shipped in secrecy to the Gulf of Guinea where the Agbami field is located at the end of 2007.
The Agbami vessel is especially beneficial to refineries around the world that are less complex, due to the fact lack a vacuum residiuum conversion capacity. It has 13 topside modules, that house the main process and utilities, and is able to generate 75MW of power on its own.
