Abstract

​

Today, the major portion of hydrocarbon production comes from carbonate reservoirs. Despite numerous papers addressing carbonate reservoir studies, reliable estimate of hydrocarbon reserves and planning of carbonate reservoir development are still associated with high risks. The paper discusses various approaches to geologic modeling and reserves estimate in carbonate formations applied by OOO Lukoil Uzbekistan Operating Company, which take into account basic uncertainties, allow minimizing risks and increasing project efficiency. The paper analyzes facies features of Jurassic carbonate formation in BukharoKhivinsky petroleum region, presents facies modeling results, describes procedure of evaluating reservoir geology and engineering project development, as well as Proxysimulation tool used for probabilistic estimate.

Key words:

​

carbonate reservoirs, reservoir properties, heterogeneity, depositional environment, limestone lithogenic type, petrophysical classes, facies modeling, Reservoir Engineering Status concept, Proxy-simulation, probabilistic-statistical estimate
