Micro-seismicity induced by fluid migration can be used to monitor the migration of fluids during reservoir production and hydro-fracturing operations. The seismicity is usually monitored with sparse networks of seismic sensors. The sparsity of the sensor networks degrades the accuracy of the estimated event locations. This inaccuracy often makes it impossible to infer the fluid pathways at the...

We investigate the relative importance of injection and production on spatial-temporal distribution induced seismicity at Raft River geothermal field. use time-series InSAR measurements to document surface deformation calibrate a hydro-mechanical model estimate effective stress changes imparted by production. Seismicity, located predominantly in basement, is primarily poroelastic stresses from ...

Hydroseismicity was proposed to explain the occurrence of intraplate earthquakes in regions. Koyna Warna region one of the reservoir triggered seismicity zone in India, which is an example of intraplate earthquake region. The seismicity is continuing after 45 years of impoundment of the Koyna reservoir in 1961 and 25 years of impoundment of Warna reservoir in 1985. The excess of previous maximu...

This paper aims at presenting what induced microseismicity is and how it is useful to produce source rock and tight formations. We use our 30-year experience in the field to discuss on data acquisition, processing and interpretation issues. In particular, we establish the difference between hydraulic fracture mapping and long-term monitoring of reservoir mechanical behavior. We comment on advan...

masjed soleyman dam site is located in the zagros mountain of western iran, which is one of the most seismically active zones of the alpe-himalayan belt. after impounding of dam, the seismicity of area increased considerably, showing the impact of reservoir (177 m height, 261 million m3) in changing the rate of seismicity in the area. we have analyzed the seismicity of area in terms of the spat...
