You have noted the sour gases and the process to clean it is tough. Has anyone ever thought of a unit to do so that is small, for each well, that would fit in a tractor trailer that would be portable to each well?
As always, I look forward to your wisdom or alternatives to keep this fuel from being wasted...
In my opinion, it is not tough but an expense. The problem with the small unit is each field is different and you are still producing products that have to go somewhere.
It is cheaper to bring the individual well gas production together into a common gas treat plant as is done all over the world.
The problem at the Bakken, the relative production of gas to oil is so low, it may be a near economic loss of the installation of piping and equipment to the volume of cheap gas produced. This would be even worse if you tried to make individual sized custom units to fit each well profile along with loosing the economy of scale for a large plant.
