The ongoing civil war that began in South Sudan in late 2013 has impacted oil industry operations in the Melut Rift Basin, where 1.7 billion barrels of oil reserves have been discovered to date. Although production from the Melut Basin Oil Project has had only temporary disruptions, industry personnel from elsewhere in the country have been evacuated, and it seems unlikely that exploration will resume in the basin until at least 2017. When exploration does eventually resume, our analysis indicated future explorers should find material oil volumes in the basin, and value can be created despite the likely acidic crudes. However, development costs are relatively high for an onshore sector - the basin occupies a remote location and frequently suffers floods which make roads impassable for half of the year. Operating costs are also high, being mainly driven by the export pipeline tariffs through Sudan to the Red Sea.
