Oil reserves in Iraq

[1][2] As a result of military occupation and civil unrest, the official statistics have not been revised since 2001 and are largely based on 2-D seismic data from three decades ago.

The source of the uncertainty is that due to decades of war and unrest, many of Iraq's oil wells are run down and unkept.

Iraq may prove to contain the largest extractable deposits of oil in the entire Middle East once these upgrading and facility improvements have advanced.

Long-term Iraq reconstruction costs could reach $100 billion or higher, of which more than a third will go to the oil, gas and electricity sectors.

Which seems to well become a new all-time peak year for Iraq if OPEC talks about freezing or reduce production held in April 2016 will not lead to a reduction.
