Abstract:The applications of time lapse seismic methods in reservoir monitoring are introduced in this paper, based on an analysis of the articles presented to the 65th EAGE annual meeting. Firstly, advances in time lapse seismic technology are briefly introduced in terms of data acquisition, processing and interpretation. The improvement of acquisition instruments and equipment, source inconsistency correction, time lapse signal decomposition and reservoir property analysis are discussed. Secondly, two real data examples are analyzed. One is reservoir pressure monitoring by time lapse seismic method. The other is multicomponent time lapse seismic monitoring of a miscible CO2 flooding. The advances in microseismicity for reservoir monitoring are also introduced.
Keywords:reservoir monitoring  time lapse seismic  data repeatability  warping  cross equalization processing
