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 (CVE 1.20%)Contango Oil & Gas Company (MCF), and PBF Energy Inc (PBF 1.13%) were the biggest energy movers this week. To learn more about the news that drove these stocks, check out the slideshow below.
