Yes there is plenty of oil, just Not for the U.S.......but I'm sure that will get changed one way or another.
From AFROL News:
After all, Sudan is believed to hold Africa's greatest unexploited oil resources, even greater than those of the Gulf of Guinea. US oil companies are barred from operating in Sudan and other Western companies are chased from the country by the Washington administration. The Canadian oil company Talisman Energy is even facing charges of "complicity in genocide and war crimes" in a US court due to its past engagements in Sudan. At present, Asian oil companies dominate the field in Sudan.
