 When oil shale rocks are heated (pyrolysed) in absence of oxygen it produces shale oil. The shale oil available technologies and production capacities in million bbl/year are the Enefit280, (1.7) VKG Petroter, (0.63), (while total Estonian companies production is 1.6) Brazilian Petrosix, (1.0) Fushun retorts processes, (0.9) and the newly installed ATP process in China in testing stage. The shale oil produced by these technologies is used as heavy fuel oil for heating purposes or ships fuels due to its physical properties and contaminants. The contribution of shale oil in the energy mix is increasing but up to now is insignificant.
