Last winter was rough for nearly everyone in America. It was brutally cold in the north and it wasn't that much warmer in the south. That said, there was one industry that gained while the rest of us were in pain and that's the natural gas industry. In fact, our winter misery was something pure-play natural gas producers like Southwestern Energy (NYSE:SWN), Ultra Petroleum (NASDAQ:UPL), and Cabot Oil & Gas (NYSE:COG) had been hoping to see for a long, long time.

While many of us hope that last winter was an aberration, natural gas producers like Southwestern Energy, Ultra Petroleum, and Cabot Oil & Gas hope it's the norm. That's because the trio is among the three most levered natural gas producers in America. Overall, the production of each company is at least 95% natural gas, which is why these companies want to see its price stay high for the long term.

To give investors a little more detail on each company I've created the following slideshow. It details where Southwestern Energy, Ultra Petroleum, and Cabot Oil & Gas operate as well as what steps, if any, these companies are taking to diversify away from natural gas in cases prices don't move higher in the future.
