why is fracking called unconventional
They are also known as unconventional because of the novel techniques â like fracking and horizontal drilling â used to extract the gas. Unlike shale gas, coalbed methane extraction doesnât always involve fracking â at least not in the early years of a development.hale gas and coalbed methane are known as 'unconventional' because unlike conventional sources which are found in larger, easier to access reservoirs, the gas is trapped in tiny little pockets in the shale rock or coal seams.
