f Induced Seismicity In The Oil & Gas Reservoirs Of The South & South Western Iran

Zagros Basin, extending from south to south west of Iran, is one of those large sedimentary<br>basins of the world that shows high seismicity rate (Figure 1). The purpose of this research is to<br>model and acquire the induced seismicity in the oil and gas reservoirs of this basin, resulted from<br>extraction or injection of fluids in the reservoirs.<br>A catalogue of small magnitude earthquakes in the region has been compiled based on the<br>data recorded in the period of 1990 to 2005. Small magnitude earthquakes which were recorded at<br>one, two or more stations were considered. All the data was processed, the moment magnitudes<br>were estimated and the foci of the earthquakes were allocated. One of our main interests was to<br>assess the focal depths. The data was divided to several groups according to the number of stations<br>that recorded the data or based on their level of uncertainty.
