It is H2S, not HS2. The rule of thumb is as long as you can smell it, you are OK. In higher concentrations, it knocks out your sense of smell and you don't know the danger you are in. There are several H2S wells in and around school campuses, like Hallettsville. Just look for the wind sock.

The transmission pipeline typically has higher pressure than that of the well so the compressor is used to "force" the gas into the truckline. The tank batteries are there to store the oil and saltwater until a truck can come by and unload it. Most fields don't have pipelines to the individual wells but instead have a central tank battery. There is really nothing to fear around a well unless you are smoking and stick your head inside the tanks to see its contents. That happened around here the other day and they found the two people about two hundred yards away. Also, kids getting electrocuted or mangled from hanging around pump jacks every year. They run on timers.

I should have read on before posting my reply to KT rider. I could have killed two birds wit one shoot and saved some bits or bytes or something.

Apparently there's some confusion here on my part and maybe KT rider's re the hydrogen sulfide gas. H₂S(hydrogen sulfide) is a naturally occurring gas; H₂S₂(hydrogen disulfide) is a stinky inorganic compound that quickly decomposes to H₂S and free sulfur I suppose.

In any case, you're submitting these sites all around us may in fact be hydrogen sulfide wells. Could be. I've not looked into it any further to determine that. I just assumed this was being extracted from sour gas/oil.

I decided to do a screen grab from Google Earth of the site I checked out for grins and purposes of discussion:

Thanks for the info.
