A British company searching for oil off the Falkland Islands in the South Atlantic says it has made further significant finds.
Rockhopper Exploration said it expected to start pumping oil by 2016. It needs £1.3 billion ($US2 billion) to develop the field.
On Wednesday Rockhopper said it had found further oil in its Sea Lion prospect, where it announced substantial quantities in March.
The company estimates there are 350 million barrels of recoverable oil in the field it has been exploring - enough to turn the Falklands into a significant oil production centre.
It said it expected production to peak at about 120,000 barrels per day in 2018.
The BBC reports the search for oil off the Falklands has angered Argentina, which claims sovereignty over the islands it calls Las Malvinas.
Argentina invaded the Falklands in 1982 before being defeated by Britain in a short war. It has never given up its claim to the islands.
Last year Argentina said ships sailing from its ports to the Falklands would need a special permit.
