2 Expected Oil Sands Projects Current production: ~1,000 barrels bitumen per day Recoverable reserves: ~185 billion barrels Asphaltenes: 12 to 20% - 22 to 36 billion barrels Current hydrogen consumption: 900 million standard cubic feet per day 2

3 Projected Natural Gas Supply, North America and Western Canadian Sedimentary Basin 3

4 Projected Natural Gas Pricing, North America 4

5 Cost Challenge Development & Operating The rise in energy prices has been the most dominant factor influencing project economics in the oil sands development drive. Total Purchased Gas Requirement Billion cubic feet per day Actual Projected Mining & Upgrading In Situ Source: Canada National Energy Board Canada s Oil Sands Opportunities and Challenges to 2015: An Update An Energy Market Assessment June

6 Water Challenge Oil sands operations consume large amounts of water billion barrels fresh water withdrawn from Athabasca River per year Increased fresh water demand for both current and planned projects billion barrels withdrawal per year planned Insufficient fresh water to meet demand Alberta is developing water conservation and allocation policies 6

7 Low Value Residuals Challenge Residuals Petroleum coke Deasphalted bottoms Vacuum residuals Asphalt/Asphaltenes Challenges Unused energy potential Distillate consumption for blending 30 to 50% diluent Landfilling/disposal 7

8 Gasification Helps Address the Challenges of Oil Sands Oil Sands Challenges Natural gas consumption Operating costs Water Low-value residuals generation The Gasification Solution Low value feedstocks replace need for natural gas H2 demand 1000 to 1800 std.cu.ft/barrel 7 barrels asphaltenes = 100,000 std.cu.ft/day H 2 Reduced waste management & landfilling costs Reduced freshwater usage Recycle & recovery programs
