This Is What Has Caused the Explosion in US Oil Production

Mark P.Mills writes at Forbes:

Drilling into conventional sources is like sticking a straw in a jelly donut – the petroleum is trapped in a large single formation that just flows out under pressure. Drilling into unconventional sources like oil and gas shale is quite different, more like tiramisu – the petroleum is in many layers that have to be individually tapped using horizontal drilling and fracking methods to open up the rock. Saudi Arabia has a bunch of really big jelly donuts. The United States has lots of tiramisu, plus some pretty good jelly donuts as well...

[D]evelopment of mature fracking technologies for oil and gas shale that have made previously uneconomic reserves economic, and development of other unconventional sources like tar sands and heavy oils.
