We have simply restated the range we expect for building production. We produce 3.2 million barrels a day of oil equivalent. In the U.S. we're the largest oil producer and the largest natural gas producer as well. But the caveat, as always, is that we only produce it for a positive margin. I would expect so.
People are very concerned about the price spikes.
It depends on where you are in the world. If you take a big world view, there is, in theory, almost an infinite reserve of natural gas. Not all sources have been found and some of them are in very, very difficult places, way away from the market. Gas, on the other hand, which is close to big markets, a lot of it's already been discovered. So a lot depends on the improvement in the technology to recover the reserves.
