In pore pressure prediction using Poisson ratio, is it possible to use estimated shear wave velocity utilized by wire line logs and then use Vs & Vp to do PPP?

As you know pore pressure prediction using Poisson ratio needs Vs & Vp . In old wells that we don’t have shear wave velocity log; we can estimate shear wave velocity utilizing wire line logs (NPHI, RHOB, GR, LLD, DT). Now, by this method we have Vs and Vp. Is it possible to use Vp (sonic log) and this estimated Vs to do Pore Pressure Prediction using Poisson ratio method? What are the influential problems?
