United States oil production is on the rise. In the first quarter of 2012, average domestic crude oil production topped 6 million barrels per day (bbl/day). This is the first time that U.S. quarterly oil production has been above the 6 million bbl/day mark since 1998.

According to the U.S. Energy Information Administration, this production growth is primarily the result of increases in output in North Dakota, Texas, and the Gulf of Mexico. In particular, North Dakota, as of March 2012, topped Alaska as the second largest oil producing state in the United States. This state had just surpassed California in average daily production last December. Both of these ranking changes are with respect to average daily production.

Combined, the top five oil-producing states in the U.S. (Texas, North Dakota, Alaska, California, and Oklahoma) account for more than 50% of total domestic production. The graph below shows how North Dakota’s production has been on a sharp rise since 2007. Note that this graphic reflects annual production levels, and so includes data through the end of 2011.

If North Dakota keeps up its currently production levels, it could surpass California and Alaska in total annual production for 2012.
