Tackling sub-seismic reservoir characterization challenges using forward stratigraphic modelling: The case of the Tuxen formation

The Tuxen formation in the Danish central graben is an intercalation of chalk and marl that include some important yet challenging reservoirs. In this study we used forward stratigraphic modelling to model the deposition of this formation and understand its vertical and lateral heterogeneities. Additionally, we used an innovative response surface modelling approach to perform a thorough sensitivity and risk analysis to quantify the effect of uncertain input parameters on output properties such as reservoir facies net thickness and net to gross for each studies sequence and on the full study area.
