Maybe you don't understand STO, It has production in Iran, Venazuela, and Algeria. In the North sea as well. It's reserves have been declining and as a result it is venturing into politically risky areas. Eca has continually increased reserves in North America and seeking to sell it's holdings where there is political risk. And thats just the ng acreage. Throw in the sands and reserves are potentially enourmous without exploration cost and risk.
