They needed an outsider to investigate this like they need a hole in their head...Let me ponder that for a moment.
Gas is all over the place....It's all about depth.
“In this case, though, the rocks that feed the flame are only warm — “like a cup of tea” — as well as geologically younger than expected, and shallow, Schimmelmann said. Those findings suggest the gas is being produced by a different process, whereby some sort of catalyst is creating gas from organic molecules in the shale, he said.
“This mechanism has been proposed for many years, but it was a curiosity that nobody believed in,” Schimmelmann said. “We think there’s a different pathway of gas generation in this location and that there probably is elsewhere as well.” If that’s true, and gas is naturally produced this way in other locations, “we have much more shale-gas resources than we thought,” he added.”
Clearly you have not received the memo. It’s all been caused quite recently by that evil fracking—doncha know?
