Few things are as polarizing today as the production of oil, and unconventional production (including 'fracking') is even more controversial. Whether you're for it or (more likely) against it, it's well worth knowing what is actually involved in making it happen and where the real risks are. The presenter recently left a long career in the US oil industry and will give you a view into this world without any spin or agenda and instead give you the opportunity to deepen your understanding of what it's really all about. What is 'unconventional oil'? What does the process to produce it look like on the ground? What equipment is used? What are the real environmental impacts (beyond climate change)? Whether you want to geek out about heavy equipment or to become a more-educated protester, you'll learn something new.
