World Petroleum Resources
• Light Crude Oil 300 – 500
• Heavy Crude Oil 500 – 700
• Tar Sand Bitumen – Primarily 2000 - 6000Located in Venezuela and Canada
• Oil Shale – Located in the USA, 2000 – 4000Russia, China, Estonia, Australia,Brazil and About 20 Other Countries

Major Oil Shale Technologies
• Mining and Surface Retorting
• In-Situ Retorting
• In-Situ Conversion
In-Situ Conversion Process (ICP) What is it? • Enhancement of natural maturation of kerogen by slow heating• Results in:
• thermal cracking • in-situ hydrogenation• high sweep vapor phase production • high API oil
• Temperature limited to boiling point of diesel, i.e. essentially no bottoms
Current target resources:• Oil Shale • Heavy Oil / Tar Sands
How is it done?• Electric resistance•Conductive heat transport
