What the new 2011 EIA oil supply data shows

The US Energy Information Administration (EIA) recently released full-year 2011 world oil production data. In this post, I would like show some graphs of recent data, and provide some views as to where this leads with respect to future production.

World oil supply is not growing very much

Figure 1. World crude oil and other "liquids" supply has dropped below the 1983-2005 trend line in recent years. Actual data is from EIA International Petroleum Monthly, through December 2011.

The fitted line in Figure 1 suggests a “normal” growth in oil supplies (including substitutes) of 1.6% a year, based on the 1983 to 2005 pattern, or total growth of 10.2% between 2005 and 20011. Instead of 10.2%, actual growth between 2005 and 2010 amounted to only 3.0% including crude oil and substitutes.

The shortfall in oil production relative to what would  have been expected based on the 1983-2005 growth pattern amounted to 4.7 million barrels in 2011. This is far more than any country claims as spare capacity. This is no doubt one of the reasons why oil prices are as high they are now. These high oil prices tend to interfere with economic growth of oil importing nations.

The shortfall in growth especially occurred in crude oil. Figure 2, below, shows crude oil production separately from substitutes.

Between 2005 and 2011, crude oil production rose only 0.5%. It was mostly the substitutes that grew.

Why oil prices are so high: Production shortfall, Iran concerns, and low interest rates

Rising oil and gasoline prices are of concern to many people today. I see three basic issues involved:

  1. “Stalled out” growth in world oil supply
  2. Concerns about Iran
  3. Artificially low interest rates

Stalled Out Oil Supply Leads to Five Million Barrel a Day Shortfall in 2011

In my view, the biggest contributor to high oil prices is the first one–stalled out oil supply.  At this point, the interaction between oil demand and oil supply does not work in the way most people expect it would. Even if the price of oil rises, world oil production doesn’t increase by very much (Figure 1), if at all.

Figure 1. Brent oil spot price and world oil supply (broadly defined), based on EIA data.

In the words of economists, world oil supply is relatively inelastic. This is true, even though the oil supply shown in Figure 1 is what is sometimes called “All Liquids,” so includes substitutes for crude oil, such as biofuels, natural gas liquids, “refinery gain,”  and any fuels from coal-to-liquid and gas-to-liquid processes. These substitutes are not growing by enough to make up for the shortfall in crude oil growth.

If we compare recent oil production with that in the 1980s and 1990s, we see that about 2005, growth in world oil supply suddenly slowed down (Figure 2).
