Quantitative petrography as a basis for the geological modeling of carbonate reservoirs

Abstract

The construction of any geological model is based on a detailed core description, determining the mineral composition and structural features of rocks and their correlation with the other studies data. As a basis for the models of carbonate reservoirs, a template for presenting petrographic analysis results in numerical form has been proposed. An algorithm for processing petrographic data and their correlation with petrophysical parameters has been worked out. The proposed method allows lithotypization on the basis of quantitative mineral parameters and structural features of rocks, helps to distinguish significant facial signs of rocks and lithogenetic processes affecting reservoir parameters, creating an objective basis for constructing conceptual and 3D models.
