The current study is a sequel of the work presented at EAGE 2018, in Copenhagen under the title " Quantifying the Effect of Overburden Multiples on Miocene Reservoirs in the Levantine Basin". The role of the scattering effects present in this geological setting was highlighted in this earlier work. More specifically, the modelling of the elastic fields within this domain showed the presence of an interbed multiple generated at the base salt of the evaporitic sequence and interfered with the primary response from the reservoir. In the current work, we study the impact these complex scattering effects may have on the inversion for elastic parameters over the reservoir. In order to achieve this, a Wave-Equation based (WEB-AVO) inversion scheme is utilized and benchmarked against a more conventional linear technique. The results support the notion that subtle multiple events may have tremendous impact on the produced elastic parameters over the reservoir.
