摘要： Method of marine time-lapse seismic surveying the subsurface using a seismic source and a seismic receiver (11,12) at a predetermined position, which method comprises positioning the seismic source (13) at position (15); recording for this position (15) for each seismic receiver (11,12) a set of at least two repeat signals at different sea states; recording for each seismic receiver (11,12) a monitor signal assuming a model for the signal that includes the subsurface signal, differences in the subsurface signals due to changes in the subsurface, and the contributions of surface multiple reflections; determining a set of filter functions that enable eliminating the surface multiple reflections; calculating for each receiver (11,12) the estimated differences in the subsurface signals which estimated difference is a measure of changes in the subsurface signal caused by changes in the target layer in the time elapsed between recording the repeat signals and recording the monitor signal.
