Two different studies with each other at approx try to fix the date of reaching the peak of oil production. Besides not being now more sustainable from an environmental point of view, when it will begin to dry up the black gold will not even be an economic point of view: the business models will have to adapt or find alternatives to the ever-increasing cost.

The first, published in the journal "Energy & Fuels", is aimed at developing a more accurate predictive model of the Hubbert model, which document is based. Researchers at Kuwait University and the Kuwaiti Oil Company have suggested 2014 as the date after which begins the decline in oil production in anticipation of ten years before the date fixed so far.
