And that's perfectly OK.  Give it a read, consider what the author says, and go ahead and disagree by all means, but please be helpful to others and provide counter-evidence to refute the evidence presented in the article. Side note, @shaleprofile aka Enno Peters' site is referenced in the article. THE SHALE OIL PONZI SCHEME EXPLAINED: How Lousy Shale Economics Will Pull
