Reservoir Pressure Prediction Using Time-Lapse Seismic Prestack Elastic Parameter Inversion Method

In this article, the author introduces a time-lapse seismic inversion method based on the difference of seismic data at different<br>times. Based on the synthetic model bSuilt from the real data, pore pressure change SSSSin a gas reservoir is computed. Also<br>we predicted the reservoir pressure variation for a China offshore gas field as a real case study. Model experiment and real<br>data application to describe the gas pressure variation show that this method is practical and efficient.
