AkpoA Giant Developmentin Nigeria's DeepOffshore
Umbilicals and flowlines
69 km of 10’’ production flow lines in 4 loops
32 km of 10’’ water injection flow lines (4 lines)
8 km of 8’’ gas injection flow line
150 km 16’’ gas-export pipeline from AKPO to AMENAM
8 main umbilicals to subsea wells and manifolds
Subsea production system 44 wells, with vertical Christmas Trees
22 oil producers20 water injectors2 gas injectors
9 offline production manifolds
1 offline gas injection manifold
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.
