Asmari Formation is the most prolific and important hydrocarbon reservoir in south of Iran. This formation in the studied oilfield has mixed carbonate-siliciclastic lithology. Also, changes in its elastic modulus are correlatable with facies changes. To address these changes, we investigated the relation between sedimentary environment (facies) and texture with rock elastic properties (young’s modulus). Data from three wells are analyzed and used for the study of facies and young’s modulus. Based on elastic properties, facies and texture changes as well as petrophysical characteristics seven RMFs are recognized in the studied formation. To predict RMFs at any location in the field more efficiently, and capturing variations of the lateral formation properties as indicated by the post- stack seismic data, a 3D rock mechanical facies model is constructed. In this method, RMFs are correlatable between studied wells and map able by seismic attribute in the field scale. Finally, the distribution of RMFs and their related properties are recognized in the studied field.
