Where exactly is this "stripping" being done? I have two natural gas wells on my property the gas comes from the wells to a water separator through a measuring devise, then directly into the city gas line then into houses around me. So where is the "striping of other gases done"? All of the gas wells in the area do it the same way as the ones on my property.
have you had your gas analyzed? it's possible the content of your gas well is pretty close to commercial grade gas, and you don't need to have it fractioned. on the other hand, if your gas well also contains useful amounts of helium, fractioning it might be a good idea, as helium is very expensive these days
