Overview of IOCs in South Sudan

Foreign oil companies, especially Asian companies, dominate the oil sector in South Sudan. The China National Petroleum Corporation (CNPC), India's Oil and Natural Gas Corporation (ONGC) and Malaysia's Petronas hold the largest stakes in the biggest consortia in South Sudan: the Greater Nile Petroleum Operating Company (GNPOC), Petrodar, and the White Nile Petroleum Operating Company (WNPOC). France's Total also leads a consortium that controls Block B in South Sudan.

Sudanese state-owned oil company Sudapet held shares in South Sudan's oil fields until November 2011, four months after South Sudan's secession, when President Salva Kiir of South Sudan issued an order divesting Sudapet of its shares and transferring them to Nilepet, South Sudan's state-owned firm.
