[R-G] Arctic Holds 90bn Barrels of Oil and Gas Equal to Russia's Reserves

That natural gas is the equivalent of 287 billion barrels of oil.
One barrel of oil equals 5800 or so cubic feet of gas.
I'd like to read some articles on the category of undiscovered oil
and gas. Historically, how have past predictions of undiscovered
reserves panned out?
The oil amounts to, if all recoverable (not at all even close to
likely), just under three years of world supply.
energy bulletin comments as follows:
Energy Bulletin editor emeritus Adam G. writes:
This article presents the 90 billion barrels (the equivalent of just
under three years' global supply) as a "find" which the press release
does not. The USGS makes estimates of undiscovered oil based
primarily on the type of geology present rather than drilling data,
which is often unavailable. Their past methods and overestimates of
future oil discoveries have repeatedly been called into question .
The authors themselves stress in their official podcast that "these
are probabilistic estimates with a great deal of uncertainty in them"
and that the assessment includes all areas "irregardless of sea ice
or water depth".
Much of this oil can't actually be "tapped" insofar as that implies
ease of extraction. It is a cold, thick and sticky fluid which will
not move easily though the pore spaces of the rocks which hold it,
and may require heating or other high energy extraction techniques.
Such marginal resources can not be developed quickly or cheaply and
will have minimal impact on the timing of peak oil or the rate of
They (U.S.G.S) claim the oil is 13 % of undiscovered reserves. This
means undiscovered reserves come to around 692 billion barrels.
Oil terminology is extremely confusing to the point that it makes it
hard to draw conclusions from articles like this. Below is a site
that gets into the different categories.
Another article I read stated that proven reserves are at a record
1.24 trillion barrels. (there are proven, probable and possible
reserves: Proven means 90 % chance the reserves are actually there
and technically producible; probable means 50 percent chance;
possible means 10 percent chance].
But proven reserves have been also criticized as unreliable, with
many so called proven reserves deemed "political reserves."
The USGS conservative number (95% probability) for ultimately
recoverable reserves back in 2000 was 2.2 trillion barrels.
if people take undiscovered reserves to be real and buy the proven
reserves number, we're not at peak for quite a while (20 or so
years). but that's what the whole debate is about.
