Also, I can't imagine the seller would be like "hmm, this guy wants to buy gas rights on 87,000 hectares of land for $1. Sounds like a good deal!" without thinking maybe there was something special and investigated for themselves first.
I suspect it is tax evasion or a nepotism deal.

Other way around.
They bought gas rights - specifically they were interested in natural gas, but evidently the rights extend to any gas (I suppose there's an 'at room temperature' caveat in there, or this kind of right may set up some unexpected and highly unpleasant incentives).
It sounds like this was a highly speculative purchase, on land not considered hugely viable for extracting natural gas. There is, after all, the non-trivial problems & expenses around actually extracting, processing, shipping, and selling the gas(es).
