If you're using a stock screener, you've probably got the wrong idea
Stocks are dynamic, not static. There are many variables that are not in the numbers that come up on a screener. The chart, the management, analysis of the sector, analysis of the economy, guidance, earnings history, investor sentiment, comparative companies, news, etc. When people use stock screeners, they are trying to find a company that fits some form of magic formula. There really isn't a formula. There is a reason some companies trade at low P/E's. If there was a magic formula, it would be exploited too easily. Also if you are bullish on oil, read oil articles books and websites...no need to screen for companies.
I am athiest and anarchist, and the last person to ever suggest using feeling and guesswork and experience over numbers and science, but I do see investing as much more of an art than a science. I don't mean to come across harsh, but I used to use screeners. I think Buffetts advice, "read everything in sight", is a lot more helpful than screeners.
