Abstract

Summary

In this paper, we extend previous studies of time-lapse seismic analysis via incorporating lab measurements for a realistic physical model to investigate the effects of reservoir fluid substitution on time-lapse seismic assessments both inside and outside the reservoir. A three-layered physical model is formed of laterally heterogeneous reservoirs having a large thickness interval that may produce significant elastic wave scattering phenomenon and hence attenuation, and filled with oil, gas and water. The modelled 4D seismic responses with high repeatability and good quality for time-lapse surveys and strengthened time-lapse seismic data processing, lead to improved understanding of reservoir fluid property evolutions. Specifically, time-lapse differences of 3D surveys in reflection amplitude signatures, travel-time and frequency-dependent characteristics are strong between the oil-water substitution surveys having weak contrast of elastic properties and significant between the oil-gas substitution surveys having large perturbation of elastic properties. Seismic surveys regardless of oil-water or oil-gas substitution produce significant 4D seismic amplitude anomalies complicated by reservoirs with strong heterogeneities. The results indicate that the time-lapse seismic technique can be used as a valuable reservoir management tool for accurate identification, both qualitatively and semi-quantitatively, of fluid variations of oil production by water or gas injection in heterogeneous reservoirs.
