Vero it is hard to say exactly what the break even is for GSX as I haven't evaluated their holdings or related expenses close enough however there is some general comparisons to consider.
The cost benefits of NGLs in the shale production process have reduced the break-even price point for natural gas producers because NGLs are stripped away, priced in conjunction with crude oil prices, and then sold independently of the natural gas.
Liquid-rich regions of the Marcellus Shale region can be profitable even when the price of natural gas is near $3 per MMBtu.
Similarly, the Eagle Ford Shale, which is considered one of the most liquid-rich plays in the nation, has an estimated break-even price point for natural gas that is below $2 per MMBtu.
