The term reservoir triggered seismicity rts is now the accepted term used to describe the phenomena of earthquakes occurring in the vicinity of manmade water reservoirs. Pdf reservoir induced seismicitya new model metin ger. Building robust models to forecast the induced seismicity. Induced seismicity refers to typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the earths crust. A detailed view of the injectioninduced seismicity in a. Abstractin most cases of reservoirinduced seismicity, seismicity follows the impoundment, large lakelevel changes, or. Hydraulic fracturing and cyclic steaming are capable of generating thousands of microearthquakes with magnitudes typically ranging from mw4 to mw1. Tno 2014 r11761 3 46 1 introduction pressure maintenance by injection of nitrogen into a reservoir is considered to be one of the potential options to mitigate induced seismicity during gas production. At some reservoirs, seismicity begins almost immediately following the first filling of the reservoir. Because of the large areal extent of the reservoir, the long history of depletion, and the available data sets which exist as a result of consequences and public unrest caused by induced seismicity, the. This initial seismicity is ascribable to the coupled poroelastic response of the. A detailed understanding of the physical processes associated with reservoir induced seismicity is required for assessing and eventually mitigating the seismic risk. In some cases, the isolation of a single mechanism is simple e.
