What input data do i need to perform acoustic impedance inversion. I have 2D seismic data and logs, but no sonic or density logs... I know that I can calculate sonic log from resistivity using Faust's equation, and from that density and AI, but is that a good practice, will it give me correct results?
Note: the logs i have are
SP,
GR, Neutron Gamma-ray, resistivity and caliper
