But it hasn't. *the rate of discovery has FALLEN steadily over the
last 50 years and rate of consumption has increased.

If you take only the discovery of entirely new fields, that is correct. If
you count all new discoveries, including the extension of existing fields,
oil reserves have been consistently growing faster than the rate of increase
of consumption. Oddly enough, it is easier to find oil where you already
know it exists than in entirely new areas.

My understanding was that those figures for discoveries were for "all
known reserveves" and did include extensions to existing oilfields. I
mean the ones used he http://www.oilposter.org/ Do you have a
reference for total reserves growing faster than consumption? I'd like
to take a look. I

Of course, there is a big problem getting reliable figures, especially
from national oil companies, about what their reserves are, but that's
a different matter.
