Sequential Indicator Simulations maps of porosity, depth and thickness of Miocene clastic sediments in the Kloštar Field, Northern Croatia

Data from selected Lower Pontian sandstone reservoir in the Klosˇtar Field, situated in the Sava Depression (Northern Croatia), were used for mapping with Sequential Indicator Simulations rather than using a classical approach. Such approaches offer better insight in distribution of geological variables or zonal uncertainties in the cases with larger datasets (15 points or more). Obtained maps of porosity and reservoir thickness are presented here along with probability maps of certain selected cut of values of petrophysical parameters. Maps showed distinct sedimentological features that can clearly be observed on the both sets of maps.
