Hydraulic fracturing (fracking) is a technique used to extract hydrocarbons trapped in certain types of rock. In particular the widespread use of fracking is being driven by the expansion in shale gas extraction.

How does hydraulic fracturing work?

Hydraulic fracturing uses pressurised fluid to free trapped gas. Wells are drilled and the fracking fluid injected into them under high pressure to crack the rock. The fracking fluid consists of water, sand and a massive amount of chemicals. Millions of gallons of water (and hundreds of tons of chemicals) are used to frack a well.

How can I find out more?

This page is a very brief overview. Please visit the resources section of this website to find out more and read technical reports related to fracking. We also have links to a number of videos that can explain the issues and demonstrate the points above.
