Sažetak
There is large set of hydrocarbon fields and reservoirs that had been geostatistically analysed in the Croatian part of Pannonian Basin, i.e. in the Sava or Drava Depressions. Analyses had been done by programs Variowin 2.21TM (freeware), Landmark(TM) application RC2, Surfer 8.0TM, 3DFieldTM, RC2 and Petrel(TM). In the western part of the Sava Depression are analysed four fields. In the Voloder and Okoli Fields permeability and porosity in sandstone reservoirs of Lower Pontian age had been modelled by vertical 1D variograms. In the Ivanić-Grad Field porosity had been analysed in sandstones of Upper Pannonian age and interpolated by Ordinary Kriging. In the Kloštar Field target were Lower Pontian sandstones. In the western part of the Drava Depression geostatistical analyses are performed at Molve, Kalinovac and Stari Gradac-Barcs Nyugat Fields in reservoirs of Devonian, Triassic and Neogene ages. There are selected the best variogram model for each lithofacies in entire structural zone, followed by representative porosity map. The clastics of Badenian age in the Stari Gradac-Barcs Nyugat Field had been specially detailed analysed with stochastical geostatistical methods and maps. In the eastern part of the Drava Depression in the Beničanci Field experimental variograms in 2D had been calculated for porosity in breccias reservoir of Badenian age and interpolated by Ordinary Kriging. But, only 1D vertical experimental variograms are calculated in the Ladislavci-Kučanci Field for porosities and permeabilities values in Badenian reservoir. In the Bjelovar Subdepression are calculated comprehensive set of only 1D experimental variograms for porosity and permeability core data (without maps). The valid results are obtained in Badenian and Lower Pontian sediments.
