BISMARCK, N.D. (AP) - North Dakota oil drillers produced a record 152.9 million barrels of crude in 2011, or nearly 40 million more barrels than the previous record set a year earlier.
    
State Industrial Commission records released Wednesday show that North Dakota produced an average of 534,884 barrels daily in December, up from 344,122 in December 2010.
    
State records show the state had 6,565 producing oil wells in December, or 1,210 more wells than in December 2010.
    
December production figures were the latest available, because oil production numbers typically lag at least two months.
