Petroleum
Extensive petroleum exploration first began in Sudan in the mid-1970s. Significant finds were made in the Upper Nile region and commercial quantities of oil began to be exported in October 2000, reducing Sudan’s outflow of foreign exchange for imported petroleum products. Today, oil is an important export industry in Sudan. Estimates suggest that oil accounts for between 70% and 90% of Sudan's total exports. The primary importers of Sudanese oil are Japan, China, South Korea, Indonesia, and India.
Most of Sudan's oil reserves are located in the Muglad and Melut rift basins in the south of the country. Oil fields in the south, such as those at Heglig and in the South Sudanese state of Unity, formerly part of Sudanese territory, are linked to the country's refineries via pipelines. The two largest oil pipelines are the Greater Nile Oil Pipeline, which travels 1,600 kilometres from the Unity oil field to Port Sudan on the Red Sea via Khartoum, and the PetroDar pipeline, which extends 1,380 kilometres from the Palogue oil field in the Melut Basin to Port Sudan.
Crude oil from the Muglad Basin is known as "Nile Blend" and is refined at the Khartoum crude oil refinery. In 2006, the China National Petroleum Corporation upgraded the Khartoum refinery, doubling its capacity to 100,000 barrels per day (16,000 m3/d). Oil from the Melud Basin is known as "Dar Blend" and is refined at the Port Sudan Refinery, which has a capacity of 21,700 barrels per day (3,450 m3/d). In 2005, the Sudanese government contracted Petronas to build a new refinery at Port Sudan.
Sudan's crude oil output is predicted to peak in 2008, although current revenue levels may be sustained for a decade or more.
