The recent price crash in crude oil, if it lasts for any length of time, will certainly affect oil production. The question is, just how great an effect will it have an how soon? But in this post I want to concentrate on what is, or was, happening to world oil production even before the price crash. Russia, the largest producer of crude oil in the world, will peak in 2014. There are various estimates of how fast their production will decline but best case, for Russia, puts their decline at about 2% per year. They say they are depending on the Bazhenov Shale and Arctic offshore just to keep production flat in 2015. Well that is not going to happen, not in the next few years anyway. And if prices stay in the current range it is unlikely to ever happen. OPEC is a wild card but there is little doubt that they are producing flat out right now. Only Iran has any real any real chance of increasing production very much and that only if sanctions are lifted. Libya has already increased production significantly and could increase more but very little. With the violence still going on in Libya, there is a greater chance that their production will decline.
