SPS doubts

The Saudis do have hundreds of years of their own oil. But other
extractors have at most a few decades left; when they're through, the
Saudis will have to increase production ten-fold to meet world needs,
and then will have only a few decades left of their own oil.

Though the whole business is somewhat shrouded in secrecy. Somebody
pointed to the Hubbert's Peak stuff which is probably a little on the
alarmist side, but the truth can't be too far from it, as far as oil is
concerned.
