The semi-autonomous region is conducting nowadays a referendum on self-determination which would lead to the establishment of a new African state devoid of infrastructure and ravaged by war.
"One is Bloc B, the biggest in southern Sudan, to Total. They will start exploration in March. And another bloc is Bloc E with Star Petroleum, a Spanish company," said minister Garang Diing to the Agence France Presse.
"We estimate that these two blocs have huge reserves which could allow us to add three times the current production to reach maybe two million bpd around 2014 to 2015."
The minister estimated the South produces 450,000 barrel per day
