Well no matter how it gets stored it has to go somewhere. And I would think the volume of some synthetic polymer would approximate the polymers it came from, so it wouldn't take much more space if any as the oil it came from. Maybe it could even be pumped back into the wells. If bacteria get at them, they were going to get at the oil anyway. And their process might be slow enough to not cause a disruption, so it might not be a big deal.

I wonder how fast the carbon was sequestered to produce oil in the natural process. We don't know how much oil there is in the ground, so we really can't tell how much faster we are releasing it than it was captured. I wonder if there's data on the effect on the biosphere from that process and some other way to gauge the speed and also total carbon that has been sequestered naturally to create oil and gas.
