Estimates of petroleum reserves come and go. There are so many new discoveries popping up, I am afraid to trust those estimates. We were surprised to find out that the shale deposits could be worked by lateral drilling to become so productive. Of course this takes a lot of water to fracture the wells, but can you think of a better use for processed sewage water?
Some governments withhold their information, so it is really impossible to get a good idea of what is out there to be exploited. I see where it is now thought that the Brazilian Tupi off shore field has twice the reserves that the government said it did.
Who knows how much the Bohai Bay deposits off the China coast hold? China isn't saying. Maybe they don't know.
It looks like the world will depend upon coal, oil and natural gas for a long time. The Japanese reactor problem has set the future of nuclear energy back another generation. Maybe that is for the best.
