In case you forgot after EXCO Resources (NYSE: XCO) made the deal to buy acreage in the Eagle Ford Shale to then sell part of it back to investment group KKR (KKR 2.00%), EXCO is very good at producing natural gas on the cheap, and it showed this past quarter. It's not that the company produced more oil and gas than expected -- it was how cheap it was able to do it. So while overall earnings numbers were a little discouraging, EXCO's ability to translate efficient operations from its core in the Haynesville to the Eagle Ford could mean good things.

For those investors who saw this recent quarterly result and put EXCO back on their radars, remember that there are still a few concerns to look at before making an investment decision. Find out what they are by tuning into the video below.
