 What areas of shale energy research do you feel need more study? I think one of the major questions is still what is the impact to human health on the industrialization that comes along with gas shale production. And there has been some statistical studies that suggest that there are slight changes to human health in the presence of such industrialization. Now we know, for example, that the presence of highways, the presence of factories and a bunch of other manufacturing facilities do impact human health, so that hydraulic fracturing is going to be no exception to that. Another area of research that is going to affect the industry a great deal concerns the issue of fracture stages in well bores. It's known that most of the economic value of a particular well comes from about one-third of the fracture stages. The most expensive part of hydraulic fracturing is not the drilling of the well, but rather the stimulation of that well. And if an operator can eliminate two-thirds of the stages for fracturing and benefit from those one-thirds of the stages that produce a lot of gas, then a lot of money will be saved. And so I've named two of what I think may be the most significant areas for research and there obviously are others that are less pressing.
