oil prices 2013 fixed through various price swaps , devon has fixed the price it will receive in 2005 on a portion of its oil production . the following table includes information on this fixed-price production by area . where necessary , the prices have been adjusted for certain transportation costs that are netted against the prices recorded by devon. .

Question: how much of the oil production is estimated to be produced from unproved reserves at dec 31 , 2004 , in mmbbls?
