The Wood River Refinery is an oil refinery located in Roxana, Illinois, approximately 15 miles (24 km) north of St. Louis, Missouri, on the east side of the Mississippi River. The refinery is currently owned by Phillips 66 and Cenovus Energy, and operated by the joint-venture company WRB Refining, LLC (WRB). WRB was formed on 1 July 2007, with Encana taking a 49% interest in Wood River and also ConocoPhillips' Borger refinery. Encana subsequently spun off heavy oil producer Cenovus and ConocoPhillips spun-off Phillips 66. In return for a 49% stake in the refinery, ConocoPhillips gained a joint interest in two Alberta oil sands (bitumen) heavy oil projects: Christina_Lake_(Alberta) and Foster Creek. Both are operated by Cenovus using SAGD (steam-assisted gravity drainage) technology.
The complex is capable of refining 306,000 barrels (48,700 m3) of crude oil per day and is the largest refinery operated by ConocoPhillips. Oil is supplied from the Gulf of Mexico, Canada, and domestic sources through pipelines. The facility produces 165,000 barrels per day (26,200 m3/d) of gasoline, 90,000 barrels per day (14,000 m3/d) of diesel and jet fuels, as well as other products including asphalt, propane, and chemical feedstocks.
A new four-drum coker, part of Wood River Refinery's Coker and Refinery Expansion (CORE) was completed in November 2011. The new coker has a capacity of 65,000 barrels per day and is expected to expand the capacity to handle the bitumen from the Alberta oil sands by nearly 700%. The new Wood River coker's processing capacity is approximately 200,000 - 220,000 barrels per day. The CORE project took about three years to build, with a total cost of US $3.8 billion (US $1.9 billion to Cenovus), and has increased clean product yield by 5% to approximately 85%. While the expansion was undertaken specifically to handle heavy oil imported from Alberta, the refined transportation fuels products are destined for the U.S. Midwest market, including St. Louis and Chicago not Canada.
Wood River Refinery was originally built by Shell in 1917. In the late 1990s, Shell and Texaco merged their downstream segments to form the Motiva (with Saudi national oil company Saudi ARAMCO) and Equilon joint ventures. During a prolonged period of low refining profit margins, Equilon sold the refinery to Tosco in 2003. Shortly thereafter, Phillips Petroleum acquired Tosco. When Conoco and Phillips merged, the refinery became an asset of ConocoPhillips. Multiple ownership of refineries is not uncommon in the United States, where many refineries (in original form) predate World War II.
