Coupled Stratigraphic and Diagenetic Forward Modelling as Input to Seismic Simulation for a Better Understanding of Carbonate Reservoirs

Carbonate rocks are generally considered to be complex, heterogeneous, and as a result very difficult to predict in terms of reservoir property, architecture from seismic interpretation. The core of our proposed scientific method is to interlock sedimentology and stratigraphy together with geophysics in a forward modelling loop. In other words to pose and try to resolve the equation of the stratigraphic architecture, depositional facies, and diagenesis of carbonate plays versus the seismic response. Practically, this approach is meant to understand and explicit (i.e. forward model) the carbonate reservoirs in order to increase their interpretation and prediction robustness. This approach is multi-disciplinary and integrates measurements and knowledge of the carbonates at all scales, from grain to basin scale, from thin section to seismic data. The keystones of the method are : 1. the interlocking of the forward stratigraphic and diagenetic modeling with the seismic modeling. 2. the integration of the diagenetic overprint in the petro-elastic signature
