Injection Related Induced Seismicity and its relevance to Nitrogen Injection: Main findings, recommendations and general guidelines.

Pressure maintenance by injection of nitrogen into a reservoir is considered as one of the potential options to mitigate induced seismicity during gas production. As seismicity in producing gas reservoirs is a consequence of stress changes caused by the decline in pore pressures and ongoing (differential) compaction of the reservoir rocks, it is expected that seismicity and the seismic hazard can be reduced by decreasing these stress changes and the compaction by maintaining the pore pressure in the reservoir rocks.
