The extraction of shale gas both in the UK and globally is currently one of the hot topics of environmental science. A vigorous debate exists between industrial companies who wish to pursue extraction of methane through a process of hydraulic fracturing (‘fracking’) and environmental groups who are insistent that methane extraction will be detrimental to the environment in numerous ways. This debate is largely fuelled by the persistent coverage of the negative aspects of fracking, as well as perhaps a sense of distrust towards the hydrocarbon industry. However, what is ubiquitous in these debates is a general lack of understanding of the core geoscience and technical aspects of extraction. This information is required, not just for governing bodies and industrial organisations to have an empirical foundation for actions, but also to engender a sense of public confidence through transparency and recognition of a scientifically rigorous basis.
