Shares of Western Refining (NYSE: WNR) soared after the company acquired the general partner interest and 38.7% of the limited partnership of Northern Tier Energy LP (UNKNOWN:NTI.DL). The move was beneficial in two ways. First, Western Refining is diversifying its business, adding a new geographic area to its portfolio and significantly increasing its total refining capacity. Second, while Northern Tier is still a one-trick pony with one Minnesota refinery, Western will be adding capacity that is strategically located to access cheap crude oil from the Williston Basin in nearby North Dakota.
