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.
These are my notes from a seminar I attended last night. Anyone interested in shale gas and fracking should find them of interest. The event was recorded, and will hopefully arrive online in the near future.

Title: Risks and realities: shale gas, geology, and public opinion
‘Fracking’ is the process of induced hydraulic fracturing to extract methane gas from sub-surface shales. Recently, this process has been adopted by companies in the UK such as Cuadrilla, but the techniques have been met by public, media, and professional opposition. This is partly due to previous issues such as groundwater contamination in the US, and microseismicity induced by Cuadrilla in Lancashire when conducting a pilot test. What has become apparent is the lack of effective regulatory regimes, and their management, as well as a general paucity in empirical backing to the processes and risks. These issues need to be addressed before further shale gas exploration and extraction is conducted.
