Time-Lapse Seismic Data Inversion Constrained by a Fluid-Flow Simulator for Reservoir Monitoring Applications

We present a fluid-flow constrained inversion approach for joint interpretation of time-lapse seismic data and production data. In this approach, the full-waveform seismic inversion is integrated into the conventional history matching process. Therefore, the interpretation of time-lapse seismic data is constrained by the fluid flow simulation in the reservoir, and it automatically takes into account both saturation and pressure effects. We use a synthetic crosswell example to demonstrate the advantage of this approach.
