Alternative fossil fuels, or  ‘unconventional hydrocarbons’, are thought to present a viable partial replacement for the declining production of natural gas (methane) from conventional gas reservoirs located both onshore and offshore in rocks such as sandstone and limestone. These alternative fossil fuels are obtained from three distinct sources and employ extraction technologies which are very different to those used to extract conventional hydrocarbons.

Methane from coal includes gas recovered from active (coal mine methane or CMM) and abandoned mines (abandoned mine methane or AMM), as well as methane recovered from undisturbed coal seams (usually known as coalbed methane or CBM).

Shale gas comprises methane recovered from mudrocks and shales which have previously been considered too impermeable (‘tight’) to allow economic recovery of gas.

The third unconventional source of gas involves combustion of underground coal seams in situ to produce synthetic gas (‘syngas’).This process is usually known as ‘underground coal gasification’ (UCG).

Where would methane extraction take place in Shropshire?

We are currently compiling our pages related specifically to Dudleston and potential CBM in Shropshire. These are the sites in and around Shropshire we know of.

How can I find out more?

This page is a very brief overview of what is trying to be extracted and why. 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.
