Abstract
Anyone planning to use 4D seismic for reservoir surveillance needs to know how frequently the data should be acquired over the producing field. The frequency of acquisition impacts both the quality of the 4D image and the value that can be extracted and is therefore a key commercial factor that drives the type of acquisition technology that can be afforded (narrow azimuth vs wide azimuth, hydrophones vs 4C data) and the mode of acquisition (permanent or temporary).
