After independence, South Sudan objected to Sudan charging US$34 per barrel to transport oil through the pipeline to the oil terminal at Port Sudan. With production of around 30,000 barrels per day, this was costing over a million dollars per day. In January 2012, South Sudan suspended oil production, causing a dramatic reduction in revenue and food costs to rise by 120%. In 2017, Nile Drilling & Services became South Sudan’s first locally owned and run petroleum drilling company.
