This week was one of the quietest weeks in the energy sector this year. With earnings season over, and summer vacations upon us, there wasn't a whole lot of news. That said, the news we did have led to some pretty big moves from a small handful of oil stocks.

According to S&P Capital IQ data, Cenovus Energy Inc (NYSE:CVE)Contango Oil & Gas Company (NYSEMKT:MCF), and PBF Energy Inc (NYSE:PBF) were the biggest energy movers this week. To learn more about the news that drove these stocks, check out the slideshow below.
