Certainly you would see the types of chemicals we use and the purpose. We're pumping large volumes of water and sand, principally, in fracturing operations. In doing so, you want to minimize the energy required to do that. So you put in, for example, trace amounts of chemicals that are friction reducers that will slick up the water. That will be mentioned on there.
As well there might be.... Oftentimes the water comes from subsurface, as I mentioned in my talk, but when you're just starting out a development, you'll oftentimes get water from surface water supplies, assuming the capacity is there. This water tends to have bacteria in it that could foul your formation, so you'll add in a biocide to take care of the bacteria.
The chemicals would be listed on that form, and the purpose, as I mentioned, as gelling agent or biocide. Furthermore, it would have information that.... It's all transparent and available to the public on a location-by-location basis in terms of the actual chemical names, the company, the supplier, the components, and the chemical abstract number. So it's very detailed information.
