Abstract
Abstract. Hydraulic fracturing for natural gas extraction from unconventional
reservoirs has not only impacted the global energy landscape but has also
raised concerns over its potential environmental impacts. The concept of
“features, events and processes” (FEP) refers to identifying and selecting
the most relevant factors for safety assessment studies. In the context of
hydraulic fracturing we constructed a comprehensive FEP database and applied
it to six key focused scenarios defined under the scope of FracRisk project
(http://www.fracrisk.eu, last access: 17 August 2018). The FEP database is ranked to show the relevance of each
item in the FEP list per scenario. The main goal of the work is to illustrate
the FEP database applicability to develop a conceptual model for
regional-scale stray gas migration.
