Unconventional hydrocarbons explained.
Discussions about energy and fossil fuels often involve scientific and technical terms, below are some simple definitions of the more complicated or unfamiliar vocabulary relating to unconventional hydrocarbons in energy production:
Unconventional hydrocarbons = This refers to unconventional gas and unconventional oil (see definitions below)
Unconventional gas = This refers to either shale gas, coal bed methane, underground coal gasification or tight gas. All four of which involve the process of fracking.
Unconventional oil = Oil obtained by other methods than drilling a hole in the ground. This means: oil shale, oil sands (often called tar sands), heavy oil, oil produced synthetically from coal and natural gas, natural gas liquids, and lease condensate. Lease condensate is recovered as a liquid bi-product of natural gas extraction at the well (or lease).
