$17 billion integrated oil stock Hess ( HES) may not get the attention of the supermajors, but that doesn't mean that you should eschew this energy firm. Hess may be best known for more than 1,360 gas stations spread across the Eastern U.S., but the firm's bread and butter is oil production. Hess has a portfolio of oil and gas projects throughout North America, Australia, North Africa and the Middle East that flow through to Hess' refinery capacity of more than 280,000 barrels a day. The firm's total proven reserves currently stand at 1.5 billion barrels of oil equivalent. >>9 Oil Stocks With Hot Prospects Hess has been transitioning in a big way in the last few years.

Hess is also one of David Einhorn's Greenlight Capital holdings.
