In this work laboratory ultrasonic measurements are performed on the 10 carbonate samples and waveforms are recorded under different conditions including varying pore-fluid type, confining and pore pressure and partial saturation. P- and S-wave velocities are measured on the basis of the first arrivals and the attenuation of P-waves is estimated by use of the spectrum-ratio method on the transmitted signals. The sensitivity analysis based on the experimental results show that P-wave attenuation is one of the most sensitive indicators for rock porosity and permeability, especially for low porosity rocks. P-wave attenuation is then used to identify the high quality carbonate reservoirs from the actual stratum on the basis of the post-stack seismic data. The prediction results are in good agreement with the well log production reports, validating P-wave attenuation as an effective indicator for directly identifying in-situ carbonate reservoirs.
