Abstract
The pressure dependence of the velocity and absorption coefficient of seismic/acoustic waves in rock is an extensively explored rock physical problem. Based on simple physical assumptions, a new petrophysical model is developed, through which a relationship between velocity and pressure is set up and explained. The material parameters of the model are determined by using laboratory measurements data and linearized inversion method.
