The Oil Drum has a great concise piece on oil production available on its site right now. It's also available in .pdf format or in Power Point for presentations. It covers the US history of oil, world history of oil, as well as the most recent data showing the current (and projected) state of affairs in terms of supply / production. It also addresses some of the current myths being circulated about how the Alberta oil sands (aka tar sands), Alaskan Wildlife National Refuge or biofuels will turn things around. It's a must-read, especially for anyone new to the idea of Peak Oil.
