Applications of FWM and FWMod

Abstract

In the previous chapter the forward model (FWMod) and the general inversion
scheme (FWM) has been described. This chapter discusses different implementation approaches that can be used via FWM. First of all, aspects of surface multiples imaging are discussed and a strategy to image them in an optimal way is introduced. Next, it is shown how surface multiples can be very helpful when imaging ocean bottom node (OBN) data. Furthermore, it is discussed, that imaging of surface multiples, after some adjustments, opens the possibility to efficiently estimate the effective source wavelet. Further, we show that the forward model of FWM can be used for predicting events. In this way missing data reconstruction, primaries/surface multiples separation or de-blending can be performed.
