I have just read a book from Eric Laurent,a well documented investigation journalist (french) who even declares that the famous "production peak" is already far behind, and that, even with the latest big discoveries the worldwide rise in demand doesn't match with the actual and future production forecast.
According to him, a colapse in energy supply, with all it's consequences is closer than we may think.
For many different reasons,these figures are difficult to check, and are said to be shaded by "majors" since they don't serve their interests.
Just a point of view....
