RELATIONSHIP BETWEEN SEISMIC VELOCITY AND PORE PRESSURE: A CASE STUDY FROM DENIZLI BASIN, TURKIYE

The Aegean region and Denizli basin have high seismic activity and rich geothermal fields.Furthermore, a remarkable earthquake activity is also observed in the region.The pore pressure calculation for oil, gas and geothermal exploration and production in the region can be computed from the 1-D and 3-D seismic velocities determined by the analysis of seismologic data.In the frame of this study, the pore pressure of Denizli Basin was calculated using Vp velocities obtained from available literature.Obtained results were compared with geothermal wells and hot water springs in the field.We report that the information obtained from the comparison is coherent with the well data.As a result, this technique can be used to determine the pore pressure zones for the drill in geothermal areas, and can be considered as an additional information in the well location.
