There is the case of Poland ,
fracking was pushed by the government but ultimately they had to give it up ,
the gas was there but the geology wasn't

I've commented on this situation several times in the past, having had direct experience with projects there. That being said it is challenging because the fracs are not as effective due to lack of brittle characteristics in the Ordovician and Silurian shales. They get gas, just not at the rates required to make it currently economic. That being said Poland does see gas spikes in the winter and have experienced supply interruptions so they have some pressures not experienced elsewhere. Chevron along with the Polish government company are currently exploring for shale gas further south (likely in the Permian) so the fat lady hasn't finished singing yet.
