This paper briefly introduced the progress in time-lapse seismic as shown from the 76th SEG annual meeting. Topics include the repeatability of time-lapse seismic, in which we discussed the effects of shooting and receiving environments on repeatability, the effects of the cable length and its positioning accuracy and stability on repeatability, and the data processing techniques to improve repeatability, new insights into time-lapse seismic, in which we described tube wave time-lapse response, spectral decomposition, and time-lapse VSP monitoring, and problems related to application of time-lapse seismic technology. The comprehensive applications of time-lapse seismic and other geophysical data were demonstrated with the real data from an oilfield.
