Vp/Vs/Den Inversion (seisInversion)

Vp/Vs/Den Inversion (seisInversion): There are two methods for seismic inversion. The first method is (non-)Linear Conjugate Gradient method to estimate the Vp, Vs and density. Another method is Bayesian-based Support Vector Machine method to incorporate the petrophysical property and seismic attributes, which has high resolution with similar to well logs. The Vp/Vs/Den can be used to calculate the Young's modulus, Poisson Ratio, UCS, Pore Pressure and minimum horizontal stress, which will be useful to wellbore stability analysis and shale gas reservoir evaluation.
