Industry committee  Research is going on to improve the ability to take a higher percentage. I think I mentioned before, we're probably taking in the order of something under 60% of the ethane that's in the natural gas right now, and we're improving the technology to make deeper cuts, also to extract ethane from other areas, such as the off-gases from the tar sands.

Industry committee  In the case of natural gas, a little over half of the petrochemical feedstocks are being extracted from natural gas to make petrochemical products in Canada. We can do better. There are things happening at provincial levels to improve our access to the liquids for upgrading. In the case of oil, I'm guessing you're referring to the tar sands and the movement of bitumen—

Industry committee  Okay. In the case of natural gas, we can do better with what we are exporting, consuming, and burning. There is work under way. Our companies are working on better technologies for deeper cuts of the natural gas liquids from the natural gas. We're also working with some of the companies that pipeline product down to the United States to establish straddle plants, so that we can extract the liquids and then put the rest of the gas back into the system and continue it to markets.

Industry committee  The main value would be to go after certain of the liquids that are entrained in natural gas. I mean, natural gas is also a good home heating fuel. It's very efficient, and there is a definite use as an energy product. We use some natural gas as an energy product. Between about 2% and 4% of the content is natural gas liquids, specifically ethane, and that's the product we extract from it.
