The Ministry of Petroleum and Nigeria’s Oranto Petroleum signed an exploration and production-sharing agreement (EPSA) for Block B3 in Juba on 6 March and said exploration work would start immediately. Oranto will be the technical operator and 90% shareholder of the block, with state oil company Nile Petroleum (Nilepet) holding a 10% stake.The 25,150km2 Block B3 has been open for investment for almost three years after France’s Total relinquished its interest in the block created in 2012 when the ministry divided the 118,000km2 Block B into three sections.
