The paper presents a case study of facies and lithology heterogeneity and its correlation with the porosity of the Upper Silurian and Lower Devonian carbonate reservoirs on Roman Trebs oil field. The described carbonate ramp facies model shows a good correlation with the observed changes in the porosity values for the studied reservoirs. The results obtained prove the effectiveness and forecasting accuracy of the lithology and facies core analysis technique for evaluating the reservoir quality of carbonate sediments.
Key words: Roman Trebs oil field, carbonate deposits, ramp model of sedimentation, facies types of deposits, porosity.
