How to model CO2 properties such as velocity at deeper depth say 30 Km? Is there any equation to model CO2 velocity?
Continous wavelet transform Theory will help you model CO2 properties in deeper areas.
You can compute the CO2 properties depending on pressure and temperature using Span and Wagner equations. From CO2 bulk modulus and density you can compute the P-wave velocity of CO2. If you want to compute the velocity of a saturated or partially saturated rock with CO2, you need to plug the CO2 properties (bulk modulus, density and viscosity) in Biot-Gassmann theory (or variants) and you will be able to derive viscoelastic properties.
Thanks Bastien
Infact I was using the empirical equations by Span & Wagner 1996, but I could not manage to obtain the bulk modulus. Coul you please tell me how to get bulk modulus using Span & Wagner ?
