The fracking industry is under fire. So we rounded up 5 fracking stocks showing positive accounts receivable trends. It's been a really bad week for the oil and gas refining industry. A damning new report released by the Center for Public Integrity and The Weather Channel, have called out Texas regulators, saying that they don't, well, regulate the natural gas industry.

And yet, that's not nearly as bad as the firestorm of controversy that Chevron (CVX) brought on itself. After one of their hydraulic fracturing wells in Pennsylvania exploded killing a worker, the firm (the 11th most profitable in the world) apologized to the town by buying everyone a free pizza. Aaron Task, Yahoo! Finance's Editor in Chief, said the decision "turns tragedy into farce." Popular opinion still seems very split on the practice of hydraulic fracturing, commonly known as fracking. There are plenty of critics on the left who argue that fracking pollutes groundwater and causes a number of health problems for the people that live near wells. Industry experts and geologists argue that the vast majority of wells are completely sound. Methane emissions offer another argument against fracking. A recent study published in Science suggests that the benefits of natural gas, and the fact that it emits less carbon dioxide than other fossil fuels, are offset by widespread methane leaks. We decided to build a list of some of the companies that work in hydraulic fracturing and shale. We started with the holdings in the Unconventional Oil and Gas ETF (FRAK) and screened for companies that had encouraging accounts receivable trends. Accounts receivable is money that a company is owed but doesn't have yet. For receivables to decrease while revenue climbs means that the company is doing a better job of increasing its profitability.
