Fracking under the radar? is a new leaflet about acidising from The Weald Action Group (WAG).
The leaflet explains the oil or gas extraction method known as ‘acidisation’ or ‘acidising’, which, like fracking, is a ‘stimulation technique’ designed to release oil or gas tightly trapped inside the pores of rocks. While fracking is used to crack open shale, acidising is used to dissolve passageways through limestone or sandstone. Acidising uses far higher concentrations of chemicals than fracking, and brings similar risks for local people, animals and the environment.
