Implementing adaptive scaling and dynamic well-tie for quantitative 4-D seismic evaluation of a reservoir subjected to CO2 enhanced oil recovery and associated storage

•Simulated dynamic reservoir properties are less accurate farther away from wells.•4-D seismic can provide interwell estimates of changes in pressure and saturations.•Repeat pulsed-neutron log measurements are tied to 4-D seismic attributes.•Impedance and velocity changes yielded the most robust correlations to dynamic changes.•Pore volume scaled changes in CO2 and brine saturations and pressure are estimated.
