De Margerie understood like few that resource constraints are as much an opportunity as they are a challenge to the petroleum industry. Petroleum is not running out, rather the easier to extract reserves. This understanding is best reflected in how well the company he lead fared the past decade, par rapport to other multi-nationals.
No wonder then the posthumous praise de Margerie received from most sectors he had been involved with: politics, business, even sports. A real loss in many ways.
