Key words: sequence stratigraphy, parasequence, carbonate sediments.
Article describes the results of carbonate sediments investigation in Orenburg region. Work is based on detailed analysis of all geological and technological data in terms of sequence stratigraphy. Regularity of reservoir properties changing is defined during this analysis, few types of reservoirs are discovered and described by specific porosity-permeability relationships. Simulation modeling which based on updated geological model allowed to define the ways of early water breakthrough into production wells.
