Feasibility analysis and evaluation technology of time-lapse seismic reservoir monitoring

Feasibility analysis and evaluation technology of time-lapse seismic reservoir monitoring can identify the feasibility of dynamic monitoring and the reliability of result,as well as designing the solution scheme in advance aiming at the technical problems and key points. Based on the feasibility analysis and evaluation for an oilfield,combined with development status and trend of time-lapse seismic reservoir monitoring,the feasibility was evaluated comprehensively in terms of geological conditions,reservoir conditions and seismic conditions by using real field data and modeling data. Meanwhile,rock physics model and pre-stack seismic simulation was combined for quantitative interpretation feasibility analysis and evaluation on the variation of reservoir parameters. The systematic feasibility analysis provides evidences for time-lapse seismic reservoir monitoring research progress from post-stack to pre-stack seismic data,improving interpretation precision,decreasing engineering risk and ensuring the project runs smoothly.
