Joint inversion of porosity for establishing velocity-conductivity relationship by using Levenberg-Marquardt and singular value decomposition

The velocity information is very crucial in seismic processing particularly to generate seismogram synthetic and fluid type analysis. Pseudo velocity log can be constructed by using conductivity log (reverse of resistivity). The relationship of velocity and conductivity in this paper is developed by...
