Abstract: FIELD: oil production industry. SUBSTANCE: this relates to development of oil deposits with drilling new wells. According to method, increase of efficiency at later stage of development can be achieved by non-drilling of non-profitable wells and by involvement of resources which are undrained by existing net of wells. For this purpose, maps are drawn of initially extracted resources, actively extracted resources, undrained oil resources, and current oil saturated strata. Sections of locating active stock of wells are contoured on last map which are limited by value of current oil saturated stratum, and additional wells are drilled in points of contoured sections where value of undrained resources ensures profitable operation of well.
