The British energy giant is spending a lot of money to explore its natural oil reserves, in order to ensure production of at least 4 million barrels per day out to 2020.

While this may cost BP in the short term, analysts seem to think the investment is worth it. Given the ever-increasing global demand for oil and natural gas - and a low price-to-earnings ratio of nine times this year's estimates - BP seems like a safe way to play the continuing energy boom. Plus, the company is among the most committed of big oil firms to developing alternative energies, which could give BP a leg up in this emerging field.
