In this work, we present a rock physics modelling workflow for seismic reservoir characterization and monitoring feasibility analysis and its application to a carbon dioxide sequestration study in the Rock Springs Uplift, a potential storage site in Southwestern Wyoming. The study includes the calibration of a facies-dependent rock physics model using well log data and core samples in two potential reservoirs, and the application of the model to a 3D volume of seismic attributes through a Bayesian rock physics inversion method for the pre-injection reservoir characterization. The study also focuses on the derivation of a rock physics model to predict the changes in the seismic response due to saturation and pressure variations during injection for the reservoir monitoring feasibility study based on time-lapse seismic data.
