It's about time a major columnist writes about the Gold Theory of Hydrocarbon Formation.
The jury's still out on this, of course, but there is more evidence for oil replenishment than for several other late-20th Century scientific theories, such as species extinctions and global warming.
A nit, which does not in any way discredit the author's otherwise excellent article: All the oil discovered to date has been within the earth's crust. The core, last I checked, is too far down and too hot to reach with a conventional drill bit. Consequently, it's unlikely to be explored except in the realm of SciFi in the near future.
It's a good thing, too. Successfully drilling to those depths would result in the world's first man-made volcano.
