Title: Pressure and saturation change nonlinear inversion method using time-lapse seismic data
Abstract: A new pressure and saturation change nonlinear inversion method is proposed using time-lapse seismic data,which is based on hybrid optimization method and rock-physics model.The hybrid optimization method and rock-physics model used in this paper are discussed.The nonlinear inversion process is given.The new method is tested with rock-physics model calibrated with real field logging data.The sensitivity and inversion results are compared for three kinds of seismic attributes combinations.It shows that the inversion method is stable and robust and inversion precision is higher than linear inversion method.
