Presented are the results of field data analyzes on oil pools development at Orehovo-Ermakovskoye field. Given are brief summary of these pools features, geological-physical properties of reservoirs, and, also, some parameters, characterizing oil reservers depletion conditions. It is stated, that from the very beginning of such pools development, two-phase filtration occurs, and the more the number of such reservoirs within production object, the bigger is their influence on current and final production technology indices.
