The discovery well Agbami-1 was completed in January 1999 and had 331ft of net pay in a variety of zones ranging from 8,000-12,000ft. The well encountered reservoir sand saturated with oil and an overall column thickness of 400-1000ft. In 2000, the appraisal well, Agbami 2 was drilled by the drill ship Glomar Explorer which drilled through a water depth of 4800 ft and a total depth of 15,683 ft. The well encountered 609ft of net pay in a variety of zones.
Field Development And Subsea
For the project to maintain an optimum output, reservoir pressure needs to 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.

The contract for the construction of the FPSO was won by the South Korean firm Daewoo Shipping and Marine Engineering in 2005. At the end of 2007, The FPSO was completed and shipped to the Gulf of Guinea where the Agbami field is located.
The Agbami Crude stream is especially beneficial to refineries around the world that are less complex, since it lacks vacuum residuum. The FPSO has 13 topside modules that house the main processes as well as the utilities and can generate 75MW of power on its own.
