Ha ha funny....
My back of the envelope calculations shows they have produced about the same amount of gas as a large dairy farm!
Probably could have bought one of those for about the same cost as one well.
Connection to the pipeline admittedly is a little more tricky...
Mind you they would have produced about 20,000,000 litres of milk as a bi-product over 4 years worth $8M, and $600K of gas...
