Abstract
Organic geochemistry. a comparatively young scientific disciplineintegrated into the basic geological model can affect the reductionof oil and gas exploration risks. The correct use of these data, particularly on a regional level, so-called geochemical mapping, hasbeen successful in discovering the hydrocarbon reservoir. By selectingrelevant geochemical parameters (source, migration, temperatureregime) it has been possible to obtain particulary useful informationabout marginal, markedly unfavourable parts of the basin, whereexploration costs are very high.The geochemical results are used as correlation parameters, not only in exploration, but also during hydrocarbon production. They enable determination of reservoir destruction, as well as composition change of reservoir hydrocarbons.However, the combination of all geological and geopbysical methods and techniques in the course of exploration process results in the maximum effect of geochemical prospection.
