abstract = "Characterizing physical properties of near surface chalk formations is always a challenging topic. Although acoustic and electromagnetic measurements can independently provide information on different properties, little research has combined them to characterize chalk rocks. Since both EM and acoustic properties are related to the porosity, saturation, and mineral composition of the rock, we develop rock physics templates to predict P-wave velocity (Vp), S-wave velocity (Vs), and permittivity from porosity and saturation. In this work, we first estimate the IF value of the IF model independently from field P-wave velocity and porosity measurements. Then, by combining crosshole ground-penetrating radar (GPR) velocity and porosity, we also estimate the value of the cementation index. Finally, given that the IF value and cementation index are independent of porosity and water saturation, we develop three rock physics templates to link Vp, Vs, and permittivity to porosity and saturation.",
