Jon Utley has an excellent piece over at Reason about the argument that offshore and ANWR drilling can’t be helpful for many years in easing pressure on world oil prices. The biggest elements of the delay, it seems, are not the technical challenges but the political and environmental barriers:

In fact, the world oil shortage is political, not geological. In the U.S., the government prohibits drilling offshore. In Nigeria, civil strife has shut down major production. In Libya and Iran, Washington effectively blockaded and isolated the nations for years to inhibit new production. In Iraq, of course, the U.S. destroyed much of the infrastructure since the first Gulf war in 1991 and then blockaded reconstruction. In nations such as Russia and Mexico nationalism and corruption curtail increased production.

Outside of developed Western countries, the single largest reason for oil “shortages” is government incompetence and ownership of the subsoil rights so that landowners don’t benefit from oil discoveries. In Patagonia, Argentina (a nation with abundant oil), I was told how it was common for landowners to try to hide any evidence of oil seepages from underground, lest the government oil company come in and ruin their lands with no benefit to themselves. Private mineral rights ownership is the reason some 90 percent of all oil wells drilled have been in the U.S. Scientific advances and innovative engineers keep coming up with ways to both discover new fields and keep old ones in production almost indefinitely.
