When oil sells for $20&amp;#x2F;bb, oil that costs more than that to extract doesn&amp;#x27;t count towards the reserves.  As the price goes up, the reserves increase, because you can extract oil from more challenging circumstances.  This is why we&amp;#x27;ve had 20-30 years of oil reserves for the last 50 years.</text><parent_chain><item><author>tomxor</author><text>&amp;gt; The next dozen years will drain less than 1 percent of the reserves in the ground&lt;p&gt;That&amp;#x27;s actually an extremely large portion for such a short length of time (this is the entire planet we are talking about).
