Summary:
Standard techniques of geological data analysis and further static modelling include restoring of sedimentary environment of rocks and prediction of reservoir properties according to sedimentary facies distribution. In case of carbonate rocks, accuracy of reservoir properties prediction in static and hence dynamic model is not enough for confident production forecast. One of the features of carbonate rocks is a significant alteration of initial sedimentary reservoir properties by secondary transformations of rocks. Key objectives for carbonate reservoirs are identification of main drivers of reservoir productivity and their genetical interpretation and prediction of its distribution in a static and dynamic model. The present paper describes approach to the study and prediction of properties of carbonate reservoirs on example of one of the fields in the Middle East. The accuracy of the proposed approach for properties distribution confirmed by the results of new wells drilling and testing.
