I rarely post a link to a company presentation, but I suggest you look at pages 9-12 of the recent Pioneer Natural Resources investor presentation. I have NO idea whether the stock is a buy or a sell at whatever the current price is, but if they are even close to right on the amount of oil that is in the Midland, Texas area, it is a huge win for the US. I am seeing less-well-documented work of another play in deep south Texas that seems to be touted as another Eagle Ford or Bakken, and yet another elephant field in Oklahoma. If the Obama administration gets out of its enthrallment to radical environmentalists and approves LNG export terminals, which the just-appointed Energy Secretary put on hold (a very bad start to his administration), the US will see a million high-paying jobs and the trade deficit will turn positive within ten years. LNG will help the environment and break us out of the grip of far-dirtier coal.
