Abstract

Well log and seismic data obtained from Daman formation of late Oligocene formation of South Tapti field are used to evaluate petrophysical properties of reservoir. This paper follows the integrated approach to petrophysical evaluation. From the log data analysis the hydrocarbon bearing zone is in the depth range of 1865 - 1875m. The water saturation varies between 10% - 30%. The correlation of synthetic seismogram with stacked seismic section confirms the presence of hydrocarbon and appears to be of Daman Formation age. The pre-stack synthetic gather shows the amplitude decrease with offset. Since the amplitude decreased with offset, plots of P-wave, S-wave, Acoustic Impedance, Poisson ratio suggests hydrocarbon (gas) bearing reservoir and verified the class I AVO anomaly.
