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.
