Non-conventional oil is produced by using techniques other then the traditonal oil well methods.  Non-conventional oil production has a larger impact on the surrounding environment, more then using traditional extraction methods.

Some non-conventional oil production types includes: heavy oil, oil shale, biofuels, thermal depolymerization of organic matter, tar sands, and conversion of coal or natural gas to liquid hydrocarbons.

Some of the oils, will more then likely replace petro motor fuel one day as petro fuel becomes depleted and more costly to produce. The reason we do not currently replace petro fuel is because of the energy required to extract these non-conventional oils is greater then the energy we are able to produce from them.

We are currently working on methods that will increase the output of energy from these non-conventional oil methods that will increase their effieciency and increase thier value
