Estonian oil shale reserves have been estimated proceeding from the require­ments of power plants. Today, when the possibility of selling shale oil in larger amounts is becoming a reality, the oil shale reserve has to be evaluated according to the criteria of oil production. The solid-energy-carrier method of processing as a relatively new way of oil generation has economical advantages and has therefore to be considered at calculating cut-off grade for mining. The basis for using this approach has been worked out by GIS modelling. Preliminary calculations showed that the cut-off grade of oil shale could be lower than today’s 35 GJ/m2.. This could increase the mineable resource of Estonian oil shale.
