Shear Wave Velocity Estimation Utilizing Wire-Line Logs for a Carbonate Reservoir, South-West Iran

Estimation of shear wave (Vs) velocity using log data is an important approach in the seismic exploration and development of a reservoir. The velocity dispersion due to frequency difference between ultrasonic laboratory measurement on cores and low frequency is about 3.5%, and thus laboratory measur...

description Estimation of shear wave (Vs) velocity using log data is an important approach in the seismic exploration and development of a reservoir. The velocity dispersion due to frequency difference between ultrasonic laboratory measurement on cores and low frequency is about 3.5%, and thus laboratory measurement velocities are more than sonic log in this study. Therefore, we used compressional wave velocity from sonic log to predicate shear wave velocity.In this study, a new statistical method is presented to predict Vs from wireline log data. The model can predict shear wave velocity from petrophysical parameters and any pair of compressional wave velocity, porosity and density in carbonate rocks. The established method can estimate shear wave velocity in carbonate rocks with correlation coefficient of about 0.94.
