| | Abstract | | We proposed a method for predicting permeability of soils using the Kozeny-Carman equation and rock physics models where the porosity and grain size of the soil are estimated from S-wave velocity and resistivity with the unconsolidated sand model and Glover equation, respectively. In this study, we apply this method to S-wave velocity and resistivity data measured on hard sandstone core samples in the laboratory to estimate permeability of the rock. In this modeling, the shaly sand model and Archie equation are employed for modeling S-wave velocity and resistivity, respectively to estimate porosity and grain size of the rock. Comparison of estimated and measured permeability reveals that most (75%) of compared data agrees each other within the accuracy of one order of magnitude. This result indicates that the proposed method can be applicable to sedimentary rocks such as sandstone as well as soils. |
