I am wondering how much is actually left in the system with pressures so low.

I would vent the gas to atmosphere, based on your pressure. However that in itself does not really get you anywhere. You will need to fill it with something, to find leaks. When you find a leak, you will then have enough gas that you actually will need to recover it properly and then fix the leak.
Good luck,
