| | Abstract | | The ultrasonic wave experiments conducted in partially frozen brine, unconsolidated sands, consolidated porous materials within a temperature range of -15 to 25. Measurements of velocity and attenuation of compressional and shear waves calculated based on the recorded first arrive pulse waveform. In addition to the estimation of velocity and attenuation through experiment data, different rock physics models has been applied to related velocity and attenuation of P- wave and S-wave, extent of freezing, elastic modules of matrix and inclusion in porous medium to porosity. To test the validity of different rock physics models in different rock types, laboratory results compared to these theoretical prediction results. |
