Abstract
Characterizing an entire field after few appraisal wells is still a challenging effort, especially in carbonate environments. 4D forward stratigraphic modeling can be an efficient tool bridging between the relatively coarse seismic resolution and the very high resolution that wireline logs, or detailed core analysis can provide. The challenge of our study was thus to achieve fast and accurate stratigraphic numerical models of a carbonate reservoir integrated with all the available data, from seismic, wellbore logs and sedimentology. Modelling the dynamics of sedimentary systems using 4D Forward Stratigraphic Modeling and simulating the filling of sedimentary basins allowed filing the gap between geological conceptual model and geostatistical simulation.
This integrated study of a Tertiary Carbonate reservoir successfully shows that a consistent model with fine-tuned parameters is capable to reproduce all the main sedimentary process trough time to correctly match the stratigraphic architecture. Thus, this modelling study successfully mimic the stacking of a partially rimmed shelf Carbonate Platform development and progradation.
