El Dorado, Arkansas Refinery
Total throughputs at the El Dorado refinery were 74,765 barrels per day in the fourth quarter 2012 compared to 82,468 barrels per day in the fourth quarter 2011. Net barrels sold, which exclude buy/sell activity of 19,294 barrels per day, was 70,133 barrels per day in the fourth quarter 2012. This compares to 75,694 barrels per day of total sales volume in the fourth quarter 2011.
Delek US operated the refinery at 63,199 barrels per day of crude throughput during the quarter despite the continued suspension of crude oil deliveries from a non-affiliated supplier's pipeline, which has caused reduced throughput rates since May 1, 2012. El Dorado began receiving deliveries again from this pipeline in early March 2013. Delek US was able to maintain this throughput level through a combination of processing approximately 2,744 barrels per day of intermediate products from Tyler, and purchasing 17,174 barrels per day of crude supplied by rail during the fourth quarter 2012.
Direct operating expense was $27.7 million, or $4.30 per net barrel sold, which excludes buy/sell activity, in the fourth quarter 2012, compared to $22.6 million, or $3.24 per barrel sold, during the fourth quarter of 2011. This increase was primarily due to maintenance during the fourth quarter 2012. On a sequential basis, this compares to operating cost of $25.5 million, or $3.98 per net barrel sold in the third quarter 2012.
El Dorado refining margin was $12.80 per net barrel sold in the fourth quarter 2012, which was a significant improvement from $1.35 per barrel sold during the fourth quarter of 2011. This increase was due to less volatility in crude price differentials, better asphalt performance and improved crude supply mix as compared to fourth quarter 2011.
Our logistics segment includes 100 percent of the performance of Delek Logistics. Delek US beneficially owns 62.4 percent (including the 2 percent general partner interest) of all outstanding Delek Logistics units and adjustments for the publicly-held minority interest are made on a consolidated basis. Results for fourth quarter and year ended 2012 include a combination of performance from the predecessor operations, prior to November 7, 2012, and from Delek Logistics following that date.
