Sažetak
Geostatistical methods are very successfully used in Upper
Miocene (Lower Pontian) Kloštar structure modelling. Mapping of
the two variables (porosity and thickness) and their common observation in certain cut-off values gave the insight in depositional channel location, transitional lithofacies, material transport direction and variables distribution within representative Lower Pontian reservoir. It was possible to observe direction of the turbidites and role of the normal fault in detritus flow direction in the analyzed structure. Intercalation between turbiditic sandstones and basinal pelitic marls were the locations with the highest thicknesses. Sequential Indicator Simulations highlighted porosity maps as primary and thickness maps as secondary (additional) data source.
