One of the challenges of understanding and investing in refiners such as Western Refining (NYSE:WNR) and HollyFrontier (NYSE:HFC) is that the recent boom in oil production has made regional oil prices in North America jump all over the place from quarter to quarter. Since these players, as well as Northern Tier Refining (NYSE:NTI), are each situated in distinct regions of the U.S., one can benefit immensely from a particular price discrepancy while another may suffer. That doesn't necessarily mean they are bad investments, though. 

Not only are these refiners all increasing their crude capacity and generating more high value products, but there is one other benefit of the oil boom that should encourage investors in this sector. Find out what that is by tuning into the video below.
