Though USA is working alot to get its hands on shale gas/oil, but in Denmark and most other european countries there have been quite a lot resistance against it. I haven't followed the cases, just read the headlines, and its something about environmental damages are huge. That is something EU cares about, USA dont, and that's why, Denmark fx have decided not to get it's shale gas up.
Regarding Pakistan, I think that first of all the environmental factors must be considered first. We cannot get the gas/oil up and 50 years later, all these shale gas/oil rich fields are completely destroyed.
If a survey conclude, it is safe to extract, I hope Pak government doesn't give away all the rights to drilling etc. to a foregin company, and in the end, only gets 20, 30 % in royalties.... like KSA.
