Sorry I am not into these ETF's although I am a long term oil bull believer. Reserves are running out and as Don Coxe pointed out we will not get the full story on the reserves the big oil actually has due to the SEC's rule that allows the natural gas reserves on a ration of 6:1 to be counted as oil reserves. That is probably one of the reasons you are seeing companies like Exxon moving big time into natural gas - their oil is just not there or where it needs to be. As for me I am holding some Candian Oil trusts (e.g. BTE) that pay a monthly dividend altho the Canadian govenment is making them change over to corporations in 2010. If you are interested in oil company investments, I periodically check this site to hear what this guru has to say about them. http://www.mcdep.com/
