摘      要：Injection of large volumes of carbon dioxide(CO) for the purposes of greenhouse-gas emissions reduction has the potential to induce *** of proposed projects must therefore take steps to reduce the risks posed by this induced *** this paper,we examine the causes of injection-induced seismicity(IIS),and how it should be monitored and modelled,and thereby *** US case studies are found where fluids are injected into layers that are in close proximity to crystalline basement *** investigate this issue further by comparing injection and seismicity in two areas where oilfield wastewater is injected in significant volumes:Oklahoma,where fluids are injected into a basal layer,and Saskatchewan,where fluids are injected into a much shallower *** suggest that the different induced seismicity responses in these two areas are at least in part due to these different injection *** go on to outline two different approaches for modelling IIS:a statistics based approach and a physical,numerical modelling based *** modelling types have advantages and disadvantages,but share a need to be calibrated with good quality seismic monitoring data if they are to be used with any degree of *** therefore encourage the use of seismic monitoring networks at all future carbon capture and storage(CCS) sites.
