The GasFrac earnings call had a lot of interesting info.  For one, they have significantly cut their costs and are closer in costs to other techniques. 

And this quote may be of interest to out friens in the western Utica where the secret to oil extraction has yet to be deciphered;

A significant event in the quarter is that we completed a fracture or a terrace in the oil window on the Northwest section of the Eagleford that’s a relatively low pressured shallow section where economic success of alternative fracturing techniques hadn’t been viable and terrace is able to get commercial production in their well with our service.

I believe in that quote the Terrace is an E & P company but was not capitalized by the automated transcription service.
