In that case, maybe it'd be more effective to just drill for natural gas in the area and get it out of the ground before it has a chance to escape into the atmosphere? Might even turn out to be a profitable venture depending on how difficult it is to extract the gas in that area.
It's not a trapped gas deposit, it's methane in a solid form spread across vast areas of the world so there's nothing to contain it and nothing to drill into. It's unlikely to have any concentrations for high enough and long enough to ever be worth extracting.
