I bought that book "Profit from the peak" Peak oil that is, Texas tea, black gold.
$3.99 and supersaver shipping from Amazon
I'll be doing some more investing in direct ownership of oil wells, but making the right choice of what companies to buy into as General Partner is very important.
Lots of hucksters in the business, snake oil salesmen. Everyone has their hand in the till, get to many administrators and the profits to you go from spectacular, to being happy to just get your money back at all.
But the moral of this chart from EIA data is that we haven't hit peak oil. And some of the Deep Bakkan US field with horizontal drilling could be a game changer. Direct ownership of energy producing assets is better than "money in the bank" IMHO.
