Abstract: The share of hard-to-recover (HTR) reserves in the total structure of reserves is increasing year by year, thus there is a growing interest in identifying effective technologies for the development of deposits containing these reserves. The paper overviews the problems of production zones of dual development taking into account the geological and physical conditions of the actual field with deteriorated structure of residual reserves. The study showed that in production zones with lateral heterogeneity the dual development technology allows to increase both current production and final values of the oil recovery factor during the late stage of development without significant capital investments into the borehole drilling
