They do capture it; coalbed methane is a great source of natural gas in San Juan Basin. Mostly it's shallow and doesn't contain the other harmful constituents found in gas associated with crude oil (such as benzene). The irony is that without pumping out the water, the gas remains trapped in the core pores. Once that water is removed, gas can migrate through any penetration of the formation, man-made and natural.
My comment was meant to address the methane hanging around over the 4 Corners area. Why not tap that if they can do it?
Use it as an energy source.
I believe you’re addressing methane trapped in the earth.
