The only thing that makes these new “discoveries” viable is $100 a barrel oil. The wells are very expensive and are characterized with high decline rates. The same goes for the tar sands in Canada, i.e. Keystone XL pipeline. It doesn’t fly with $30 oil. The world is running out of “easy” oil. The bulk of it is either in unconventional reservoirs (Bakken, Eagle Ford, etc.,) in 7,000’ of water or greater (i.e. deepwater Gulf of Mexico and Brazil,)or in countries that don’t like dealing with the infidels. There is no longer a free oil lunch like our parents and grandparents.
