What county is that and I can tell you whether the gas is sour or not? If they are burning a flare or have a wind sock, it is sour. They will have signs at the gate saying so as well.
Dayum you’re quick! This particular one is located in Tyler County; had no flare or wind sock. I’ve not really researched it but it’s just sortof my impression that most of the wells around here are what would be considered “sour”. The gate of course was open and the only sign of any significance I remember seeing was one identifying the operator(?) - Anadarko. BTW, these generator/compressors are HUGE! A site this small surely wouldn’t need that kind of power so it must be necessary for the pressure required to do whatever it does.
