Sažetak
Geostatistics is very powerful and standard tool in geological modelling of hydrocarbon reservoirs, starting from eighties in 20th century and last to date. It includes mathematical theory developed for describing of regional variable behaviour. Today geostatistics is used widely in petroleum geology as well as other geosciences that handle by spatial distribution of regional variable. It is based on variogram analysis and different interpolation and simulation techniques. The advantages of geostatistics interpolations (different Kriging techniques) are obviously for almost every datasets that include 15 or more point data. Set of Cokriging methods allow to include one or more secondary variables to improve mapping process of primary variable. The most often example is porosity mapping supported by seismic attributes. Second group geostatistical methods encompass stochastical simulations. This very useful tool allows creating a set of equiprobable realizations of mapped variable. Particular realization can be selected based on several geological criteria.
