Do you have a link?
My knowledge about the methane deposits came about when we were having methane leak into water supplies in Texas a while back and deposits exploding willy nilly in Texas and Oklahoma. Common knowedge from the industry was that if they filled mined cavities with water, it would preclude oxygen from seeping in, mixing with the methane and causing unhappy explosions. It turned out the water pumped into the “sealed” methane gas cavities flowed out and was replaced with air that mixed with the methane and resulted in willy nilly explosions. From that, researchers determined the methane cavities are not sealed or isolated as claimed by the oil and gas “experts.”
It was a long term research event...I am not going to go back and research it all again to give you links. Smokin’joe apparently is an expert on methane deposits in North America and all this so I asked him to give us links to his research in the area.
