Here's some proven reserve info from today off the net:
"The Oil Sands of Canada hold recoverable reserves of 175 billion barrels with a proven reserve life of 480 years and another 130 billion barrels of
potential reserves, which is second only to Saudi Arabia's 262 billion barrels."

And that's just the Oil Sands that we currently have the tech to exploit.
Some folks feel this is a conservative estimate, others don't.
