How Changing The Definition Of Oil Has Deceived Policy Makers

Everyone knows that world oil production has been running In North America it would take 1.8 billion acres to grow enough corn to supply enough ethanol to run the North American vehicle fleet. That's four and one-half times the amount of arable land available. And besides, corn ethanol takes more energy to produce than it provides. It's not an energy source so much as an energy carrier. Similar limitations apply to biodiesel which is made from vegetable oil.

The remaining volume of total liquids production, about 2 mbpd, is what is called refinery gain. Simply put, the total volume of crude oil increases once it is separated into its various fractions. This is not a source of oil so much as a consequence of spending energy to refine it.

Even when non-oil products are considered, total liquids have barely budged, up just 3.5 percent for the entire period from 2005 to 2011. Even if these liquids were interchangeable with oil, they would be making very little headway in substituting for it.

But because few of the non-oil products now being lumped in with oil supplies are genuine substitutes and the ones that are have serious limitations on the volume they could provide, we should consider the truth about oil. Its supply is stagnant which accounts for the record prices of recent years. And, the promise that high prices would bring on copious new supplies has proven to be nothing more than wishful thinking.

The limitations on oil supplies are now upon us. The salient issue is the rate of production, not the supposedly huge resources that optimists may conjure up in their imaginations. How much oil you can get out out of the ground on a daily basis is what counts, and it's getting harder and harder to extract the amount of oil we desire from the Earth's crust each day. We extracted the easy stuff first. We cannot now expect to extract the difficult stuff at the same high rates as the easy stuff. And, we cannot expect that total percentage recoveries from the smaller, more complex and challenging reservoirs which we are now forced to exploit will be as high as those we've gotten from large, simple, straightforward reservoirs in the past.

Facing up to this reality will be difficult because it will require so many changes in our thinking and our society. And, it would require the immediate markdown of the value of one of the world's largest and most powerful industries because it now faces contraction in the not-too-distant future. No wonder the powers that be decided to change the definition oil instead of accepting reality.
