Well, my opinion about what the oil price could be is certainly not what the oil price has been. I'm going to guess that we're not likely to get much above $60 in the future and that this is going to be a world price for oil that will reflect the cost of extraction and processing. That may not be sufficient to incent smaller and newer firms to participate. In fact, it probably leans back toward those well-established firms that can afford the investment.
Let me just give you one really short example. Years ago some of the Shell engineers were experimenting with using carbon dioxide as a medium to be able to move petroleum coke in a pipeline. In other words, they were trying to create a slurry using carbon dioxide at such pressure that it created a liquid, to be able to move both of those products to locations farther south, for instance, where they could be injected or neutralized. That didn't come from government incentives, but from their trying to creatively problem-solve how to deal with future constraints on carbon dioxide. I think that's likely to be sponsored very well only by the larger and pre-existing firms.
