Activity: Liquefied Natural Gas Plant
Angola is a world-class hydrocarbon region and its
role is expected to increase in the future, according
to the leaders of the Angola LNG project. This Com-
pany intends to exploit Angola’s great economic po-
tential in an environmentally friendly manner whilst
maintaining strong links with individuals and com-
munities in the area. Angola is seeking a solution
to reduce emissions and establish a new source of
clean energy for the US, the Atlantic Basin countries,
and for use in the Angolan domestic market. Angola
LNG is endeavoring to find this solution.
Considerable amounts of gas are emitted as a re-
sult of oil extraction. Once cooled to temperatures
of around -260º F (-160º C), the gas condenses into
a liquid, making it safe and economical to transport
over long distances, thus helping to reduce dra-
matically the heavy cost of pipelines. Liquefaction
removes oxygen, carbon dioxide, sulfur and water
from the natural gas, resulting in Liquefied Natural
Gas (LNG) that has a composition close to pure
methane. Angola LNG is striving to develop this
process.
As well as offering a solution to reduce greenhouse
gases LNG will also bring additional economical ben-
efits: it can be used for petrochemicals, as fuel for
electric power plants or as seasonal gas reserves.
Angola LNG is the largest project ever built in An-
gola, with a total investment of US$ 9 billion. The
construction of this mega-plant based in Soyo (Zaire
province) has required the participation of 7.000
qualified workers (60% of them were Angolan).
Although the idea emerged in 1997, the first part-
nership agreement between Sonangol, Texaco and
Chevron took place in 2002. The Final Investment
Decision was signed in December 2007 after Total,
Eni and BP joined the partnership.
As the largest producer of oil in sub-Saharan Africa,
Angola is a key player in the African Oil & Gas mar-
ket. An estimated 50 significant new deepwater dis-
coveries in Blocks 14, 15, 17 and 18 are expected to
come on stream in the next five to ten years. Prelimi-
nary studies indicate that those 4 blocks should con-
tain more than 10 billion barrels of recoverable oil.
Above all, over 10 trillion cubic feet of gas reserves
will become available. These figures are expected
to increase as oil and gas operations continue to
expand.
Angola LNG Project will provide critical revenue to
Angola and establish the foundation for development
of a domestic gas business.
Angola’s deep and ultra-deep waters are considered
to have significant potential yet to be explored. Asso-
ciated Gas (AG) will be the primary source of supply
for the LNG plant in the early years of operation. As
oil fields mature and associated gas production de-
clines, the plant will be fed by Non-associated Gas
(NAG) from previously discovered gas fields.
Onshore Development:
The first Liquefied Natural Gas (LNG) plant will have:
• Nominal LNG capacity of 5.2 million tonnes/year
(6.8 billion cubic meters/year)
• Storage facilities for LNG, Liquefied Petroleum Gas
(LPG) and condensate
• Loading jetty to accommodate 145,000 – 205,000
cubic meter LNG ships
It is expected that in the first quarter of 2012 pro-
duction will reach a capacity of 125 million standard
cubic feet per day (or 2.1 million cubic meters per
day) of clean gas for domestic use.
Offshore development:
The Angola LNG Project will gather associated gas
(AG), in water depths of up to 1500 meters from the
following producing blocks:
• Block 15 (ExxonMobil)
• Block 17 (Total)
• Block 18 (BP)
• Blocks 0 and 14 (Chevron)
• Future Blocks (TBD – Ultra deep water blocks)
The Angola LNG Project will also develop previous-
ly discovered non-associated gas fields in Blocks
1 and 2 to supplement the gas (AG) produced with
oil.
Gas production from these Blocks will be transport-
ed by 3 high-pressure pipelines to the LNG plant
onshore for conditioning and extraction of Natural
Gas Liquids (NGLs) before liquefaction to LNG.
