The present and future of wave impedance inversion technique

Zhang Yonggang (SINOPEC Science and Technology Development Department, Beijing 100029, China)  
Geophysical inversion is a computational process to restore subsurface geological structures and petrophysical properties from observed geophysical data.This paper outlined the evolution of seismic inversion technologies, from direct inversion to model based inversion, from linear inversion to nonlinear inversion, and from poststack inversion to prestack inversion. The inversion of elastic impedance will be one of directions of inversion development.Seismic inversion is on the way of integrating acoustic impedance with elastic impedance.
