In an August 30 Sudan Vision article, the Sudanese Minister of Energy and Mining said that the oil reserves in Sudan amount to 6 billion barrels. Current extraction is about 475-500,000 barrels per day.
At that rate, the oil in Sudan will last about 34 years before it gets depleted.
A 28 inch pipe brings oil from south central Sudan to the coast of the Red Sea, where a specalized shipping port, storage facilities and a small refinery have been built. Most oil exported by ship goes to China.
