Mike, I thought NE was thinking aloud and hoping somebody had an answer to a few thoughts.
It is clear nobody does at the moment.
Before I was put on Sertraline, I could not listen to any news of the Thai boys football team and coach who were trapped in a cave. But I have pondered their plight at length and compared it with #3 .
The parallels are a very easy way to describe what I think could be happening with gas flows.
They were trapped by rainwater flooding into the passage behind them.
No landslip afaik!
Now, suppose there was a landslip in #3's lateral well. The water would back up blocking the gas.
Clearly, water is still getting over the top of the blockage along with patches of gas, causing the fluctuations?
Assuming there is no aquifer (as NE considered) , and it is a desert around there, the water will become a trickle one day. At that point the gap above the blockage will be open and bingo, the gas won't back up like water does!
If this is what has happened, there is a case for turning up the pumps. And there is the rub!
Turn up the pumps and risk blocking #4 with coal fines?
This makes perfect sense to me , and if there is such a dilemma , I'd side with TG's approach, as usual.
