Sažetak
The mapping of facies is important task in modelling of hydrocarbon reservoirs. One of the most often methods for their description are from the set of indicator ones. Until recently, that set of methods was not used in the mapping of sandstone hydrocarbon reservoirs in the Croatian part of the Pannonian Basin System. Some of such reservoirs properties are: (1) relative small number of point data (<20), (2) irregular spatial distribution, (3) impossibility to determine borders among different lithofacies. The presented innovation included two steps applied for the better reservoir characterisation. The first one (a) was distinguishing of permeable and impermeable parts, applying original technique of indicator variable definition and lately mapping by technique generally applied for original data (Ordinary Kriging). So, it was possible the replace manual interpolation of lateral facies changing line by computer mapping. In the second step (b) indicators had been applied for recognition of even four particular lithofacies, where the characteristic variogram curves are defined, and Indicator Kriging was applied for mapping. The results made possible to follow the directions of each particular lithology (sandstones, marlitic sandstone, sandy marl and marl).
