Carbonate reservior heterogeneity. Overcoming the challenges / Карбонатные гетерогенные резервуары. Преодоление проблем

Heterogeneity is an intrinsic property of all carbonate reservoirs. The properties of these reservoirs considerably change both laterally and vertically. Lateral changes are usually the result of various depositional settings, while vertical heterogeneities are caused by basin evolution through time. Available data from these reservoirs are very limited and so predicting the distribution of properties between the wells is very complicated. The hydrocarbon in place is calculated using these predictions and so they are very important. In fact, many aspects of the reservoir studies are about heterogeneities. Facies analysis and classifications, determining sedimentary environments, reservoir rock typing, flow unit determination and sequence stratigraphy are some examples. <...>
