CVR Refining, LP and, unless the context otherwise requires, its subsidiaries ("CVR Refining," the "Partnership," "we," "us," or "our") is an independent downstream energy limited partnership with refining and related logistics assets that operates in the mid-continent region. Our common units are listed on the New York Stock Exchange ("NYSE") under the symbol "CVRR."
We are a petroleum refiner and own two of only seven refineries in Group 3 of the PADD II region of the United States. We own and operate a complex full coking medium-sour crude oil refinery in Coffeyville, Kansas with a rated capacity of 115,000 bpcd and a complex crude oil refinery in Wynnewood, Oklahoma with a rated capacity of 70,000 bpcd capable of processing 20,000 bpcd of light sour crude oil (within its rated capacity of 70,000 bpcd). The combined crude capacity represents approximately 23% of the region's refining capacity. In addition, we also control and operate supporting logistics assets including (i) approximately 570 miles of active owned, leased and joint venture pipelines, (ii) approximately 130 crude oil transports, (iii) a network of strategically located crude oil gathering tank farms, (iv) approximately 6.4 million barrels of owned and leased crude oil storage, and (v) over 4.6 million barrels of combined refined products and feedstocks storage capacity. The strategic location of our refineries, combined with our supporting logistics assets, provide us with a significant crude oil cost advantage relative to our competitors. Furthermore, our Coffeyville refinery located in southeast Kansas and the Wynnewood refinery located 65 miles south of Oklahoma City, Oklahoma, are approximately 100 miles and 130 miles, respectively, from the crude oil hub at Cushing, Oklahoma ("Cushing"), and have access to inland domestic and Canadian crude oils that are priced based on the price of WTI. During the year ended December 31, 2017, the crude oil consumed at the refineries was price advantaged to WTI.
During the fourth quarter of 2017, we entered into a joint venture, Midway Pipeline LLC ("Midway"), with a subsidiary of Plains All American Pipeline, L.P. ("Plains"), which acquired the approximately 100-mile, 16-inch pipeline that connects our Coffeyville refinery to the Cushing oil hub, and we separately acquired from Plains the approximately 100-mile, 8- and 10-inch pipeline system connecting our Wynnewood refinery to Cushing. Refer to Part II, Item 8, Note 6 ("Equity Method Investments") of this Report for a discussion of the joint venture transaction.
