Actually that isn't true. ANWR is about the only one that is relevant the others are far more expensive to drill than the old reserves were.
Untrue...
I was looking for something about the oil off the coast of California and found this gem:

One of my grandpa's pet topics actually.... more oil seeps out of the ocean floor up there now then when we were drilling heavily, Rincon and all the good breaks up there have regained their trademark sludgy surfline and people are still going nuts about one barrel spilling. The headline of that article seems a bit bold for the content.
If we were drilling there and capturing the oil, the natural seepage disappears and we get the resource, it's so win/win it's absurdity to keep acting in this manner.
