Specification 3.2.3.4 · Paper 2
Natural gas held within shale, a type of sedimentary rock.
Revise: Strategies for Increasing Energy Supply and Fossil FuelsShale gas extraction in the USA shows how increasing fossil-fuel supply can bring both advantages and disadvantages. Fracking has taken place in more than 30 US states, making it a widespread extraction strategy rather than a single small project.
Specification 6.5 · Paper 2

Domestic shale gas production can increase energy supply and reduce reliance on imported gas. This can improve energy security, because a country depends less on supplies from elsewhere. Development also creates employment.
Paper 3
Gas trapped in shale rock that does not readily flow towards a well without additional extraction techniques.
Revise: New exploitation areasUnconventional sources, including tar sands and shale gas, require additional techniques to separate the oil or release the trapped gas. Neither type is necessarily cheap or harmless to develop.
