The U.S. Energy Information Administration said on Tuesday oil production in the United States will reach a 43-year high in 2015 as output grows from shale fields.

The United States will produce 9.3 million barrels per day next year, up from a forecasted 8.5 million bpd this year, EIA said in its monthly short-term energy outlook report.

The administration also revised non-OPEC oil production for 2014 up 140,000 bpd from previous forecasts, to 56.1 million bpd. The forecast for OPEC output was revised 150,000 bpd higher to 35.4 million bpd.
