Eestimaa Õlikonsortsium (Swedish: Estländska Oljeskifferkonsortiet; English: Estonian Oil Consortium) was an oil shale company located in Sillamäe, Estonia.
However, due to recession, production halted in 1930 and was not restarted until 1936, when it was reorganized as Baltic Oil Company.
[3] In July 1938, Eestimaa Õlikonsortsium concluded a contract with the German Kriegsmarine to supply shale oil as a ship fuel.
[7] After occupation of Estonia by the Soviet Union, the company was nationalized in 1940.
[8] According to Soviet-Swedish agreement of 1941, the Soviet Union made a one-time payment in 1947, covering only part of the company's value.
