The lecture slides for my York Lifelong Learning class on Shales & Fracking can be downloaded here: 2016_intro_shalesfracking_sml
Most of the references I discussed can be found on the website for the 2015 version of this site, here.
The new British Geological Survey appraisal of the shale gas/shale oil potential of the Wessex Basin (Oct 2016) can be found here.
The new ReFINE study (Dec 2016) on how much methane is escaping through natural fault zones in the UK can be read here.
Last but not least, a new study I have been involved with, trying to understand how climate change in the Jurassic led to the formation of organic-rich shales, can be read here. A less technical article on the study can be found here.
