Document Summary

Source rock is often organic-rich, black shale: overlying porous rock allows upward migration of liquid and gaseous hydrocarbons sandstone and limestone. The porous rock has to be overlain by an impermeable layer to seal the trap: shale. 70% of oil deposits are mesozoic in age. Crude oil is a mixture of hydrocarbons (paraffins, naphthenes, aromatics, asphalitics) that is sent to refineries for further distillation into other products. Proven reserves- the estimated quantities of oil based on geological and engineering data that are considered to be recoverable in future years under current economic and operating conditions. Undiscovered resources- likely to be there given the geological setting and anticipated technology and economy. Some of the infrared radiation passes through the atmosphere but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. Nearly all the energy that is available at earth"s surface comes from the sun.
