"The reserves of oil are there, but if you don't invest they don't come on the market," Mr de Margerie said.
"What we have to decide today is production for 2010-2015. So in between we might be faced with insufficient oil to meet demand."
He said the major oil producing countries, which have cut production in the face of falling demand and to protect prices, could not be blamed for the underinvestment.
"You cannot ask those countries who are also facing a crisis to continue to invest for a potential recovery of demand, and to do this for the benefit of the world."
Instead, he called on heads of government to get involved.
"I think it is our role to... force people in charge of our countries to think about this concern we have."
