Oil, first produced in 1863, is found both in Upper Austria, near Wolfsegg am Hausruck, and in Lower Austria, in the vicinity of Vienna. After reaching a peak of about 3,700,000 tons in 1955, oil production gradually declined to 22,000 barrels per day in 2000. Natural gas production was 1.698 billion cubic metres in 1998, far short of domestic needs; consumption amounted to 6.862 billion cubic metres in that year.
