Unconventional gas

Unconventional gas is natural gas obtained from sources of production that are, in a given era and location, considered to be new and different. Sources that are at times considered to be unconventional include the following:

Coalbed methane^{[citation needed]}
Methane clathrate (gas hydrate)^{[citation needed]}
Shale gas^{[citation needed]}
Synthetic natural gas, such as oil shale gas
Tight gas^{[citation needed]}

As noted by the International Energy Agency (IEA) in 2013 regarding unconventional oil, what is conventional vs. unconventional changes over time as technologies and economies change.^[1] Certainly, this applies to unconventional gas as well.

Natural gas, whether conventionally produced or not, has been considered to be an unconventional source for oil production.

Crude oil production in 2011 stood at approximately 70 million barrels per day. Unconventional oil consists of a wider variety of liquid sources including oil sands, extra heavy oil, gas to liquids and other liquids. In general conventional oil is easier and cheaper to produce than unconventional oil. However, the categories "conventional" and "unconventional" do not remain fixed, and over time, as economic and technological conditions evolve, resources hitherto considered unconventional can migrate into the conventional category.
