Because Shale gas is normally exploited through hydraulic fracturing, its viability is still largely driven by economics. Prevailing cost of Oil/gas, and production cost drive investment decisions.
However, environmental risks such as air pollution, surface/groundwater pollution, impact on biodiversity and its potential generation of seismic activity, are increasingly becoming a cause of concern.
In addition to Joseph Nyangon paper, you can get more information on this by going through the following conference papers:
Shale/tight gas is most definitely a real alternative.
In my own investigation, I have found that worker safety during project development could be perceived as a risk. Rapid production decline, the infrastructure to deliver products and development impacts are risks as well.
