World field production of crude oil increased 2.9 million barrels a day in the 12 months ended last July. That compares with a 3.6 mb/d increase over the entire nine years from Jan 2005 to Dec 2013.
The biggest single factor is Iraq, where production is up almost 1.1 mb/d over the last year. Although ISIS has managed to bring cruelty to much of the rest of the world, so far they have not disrupted Iraqi oil production.
The second biggest factor in the 2.9 mb/d gain was the United States, where production increased 0.6 mb/d July 2014 to July 2015, thanks to the tremendous success of shale oil, or production based on horizontal fracturing of tight geologic formations.
