In the following video, Motley Fool energy analysts Joel South and Taylor Muckerman take a look at Western Refining (WNR), a refiner in the mid-continent region that blew analyst expectations out of the water this quarter. The company had an incredibly solid 2012, as well, with the stock up around 100% in the last year, all due to the availability in that region of advantaged crude feedstock from the oil production boom in the U.S. Joel tells us just how good the numbers were with this company this quarter, and what we can expect from them in the future.
