In the field's Miocene reservoir the fluid is

in ‘critical conditions’, i.e. the gas and

liquid hydrocarbons are in a single

phase, at high pressure and tempera-

ture.

The produced gas is partly re-injected

and partly exported onshore to the

BONNY liquefaction plant (NLNG) via the

AMENAM field facilities. This hybrid

injection/export gas scheme optimises

hydrocarbon recovery: gas is injected

only in reservoirs which can benefit from

this type of pressure support.

On the same OML 130 block as AKPO,

three oil discoveries (EGINA, EGINA-

SOUTH and PREOWEI) now form the

basis for an oil development with a new

FPSO located in the EGINA zone. Both

AKPO and EGINA, with their ability to

handle a variety of fluids, will be ideal

hubs for developing future hydrocarbon

discoveries in the area.

AKPO Partners

A deep offshore condensate & gas field in Nigeria

The AKPO field was discovered in 2000 by

Total Upstream Nigeria Ltd (TUPNI).

Located 150 kilometres off the Niger Delta at

a water depth of 1,400 metres, AKPO is the

first deep-offshore development involving

light oil with a high gas content.
