Fracking - outside the U.S and Canada pretty much ... ... a failure!
Let's put aside the political, environmental, and feasibility issues - all major obstacles in their own right.
Fraking has been around in the US for a long time but was not widely employed till the last twenty years or so.
In Poland and other countries it has been pretty much been a big bust. Why? It is more an art form than a science. I think many more wildcatters do better at it than larger corporations. And here is another huge impediment.
At the turn of the century in lived in Western Michigan where the "sand wars" erupted into violence as sand mining trucks came under gun fire. There were also visicipus court battles - especially pitting GM and others against Ford. Even Stewart Mott, a GM heir was adamantly against sand mining and GM.
At the time no one could really understand why the sand miners and in particular the now absorbed infamous Technisand company would go through so much time, cost, and effort for something as abundant and common such as sand.
Well eventually we discovered it was for fraking! It is of the secret sauces/ingredients for fraking. And here is the kicker - not all sand is created equal! Northern White is in particular demand for molding, fraking, etc. And for some reason I don't understand Saudi sand may not be feasible.
So I think we can pretty much rule out fraking outside North America at present just on this basis.
