Abstract

Time-lapse seismic technique is an effective method for dynamic monitoring and management of reservoir. It monitors dynamic changes of reservoirs with time by means of multiple seismic surveys. Application of this technique in thin interbed reservoir of land facies basin is an important research subject. In this paper, we introduce the time-lapse seismic monitoring of thin interbed reservoir in the Eastern China. The feasibility of time-lapse seismic monitoring is studied by rock-physics analysis and seismic modeling. After the equalization processing of time-lapse seismic data, the amplitude difference is obvious and thus the residual oil distribution is predicted.
