A poro-elastic model for triggering of production-induced earthquakes in the Groningen natural gas field by abrupt changes in well rates

Over the past decade, a steep increase in the number of seismic events has been observed in the Groningen gas producing region of the Northern Netherlands. It is generally accepted that these are induced by compaction of the reservoir rock due to extensive field depletion, causing a buildup of strain energy which may be released seismically when...
