Chad's rebels are upset with how the country handles revenue from its oil industry, experts say.

The rebellion aimed at toppling Chadian President Idriss Deby that brought fighting to the streets of the capital, N'Djamena, in recent days is in part a condemnation of how his administration uses the central African country's modest revenue from oil production.

Chad produced far less oil than neighboring Nigeria, about 200,000 barrels per day compared with Nigeria's 2 million bpd estimated output. But the relatively meager income from oil profits has not trickled down to impoverished Chadians, the rebels contest.

But unlike Nigeria's militants, Chadian rebels do not consider misappropriated oil profits the focal point of their fight, noted Africa oil expert John Ghazvinian, author of "Untapped: The Scramble for Africa's Oil."

"They'll (Chadian rebels) probably say something like 'this is corrupt government that doesn't spend its revenue on its people,'" Ghazvinian told United Press International Wednesday. "But it's a very different situation than the Niger Delta," he added, noting ethnic and political tensions foment the current violence in Chad.
