Rust in closed tanks
(OP)
What happens to the pressure inside the tank when the oxygen is used in the rusting process. Are the oxygen atoms replaced or does the internal pressure drop? I would imagine the volume change is significant going from 20% down to 5%.

2. It would also require de-aerated water, another rarity.
The only systems that I have ever seen that met those two criteria were inert gas purged to keep the water oxygen free.

Did your test say that there was a flammable gas?
After all with low oxygen it wouldn't be able to burn.
I have seen very low oxygen in closed systems with biological activity, but then it was replaced other gases. Gases such as H2S, CO2, ammonia, and so on.

1. Could the cutting torch have left residule gas as it used LPG and O2 for fuel.
2. Could the atmosphere in the well have had a small amount of combustable gas and with the rust depleting the oxygen level to a explosive range.
3 Could the explosive gas form a pocket and when ths oxygen depleted the pocket came into the explosive range. Meaning will the atoms of explosive gas and remaining oxygen stay in close proxcimity to form an explosion.
I'll have to study basic chemestry again as this has me hooked to find out what happened so we dont blow ourselves up.
