Key words: deposit, reservoir bed, effectiveness of oilfields development, watercut, completeness of oil extraction.
Massive-bedded deposits with carbonate fractured reservoirs are considered. Some of the characteristic features of the applied systems of development of two objects (Upper Devonian and Carboniferous) are marked. The possibilities of an additional optimization of the reserve recovery processes are considered. Some recommendations for improving the considered objects development, based on the analysis of project documents, the actual state of operation of some fields deposits, are systematized.
