That compared with an earlier estimate of 83.28 million bpd this year, rising 1.85 per cent in 2004.
The new forecast, which represents demand growth of 1.65 million bpd, was based on higher expectations for strong economic momentum and firm demand from developed countries and China in the final months of 2004.
The United States and big European countries were showing strong demand for oil while there were signs that booming Chinese demand might not slow as quickly as previously thought.
Nevertheless, Opec voiced confidence that its oil supply would be enough to meet demand in the months ahead.
