Key words: decline rate in oil production, interlaid reservoir, waterflood system, technogenic fracturing.
The most appropriate variant of injection and production wells pattern is always extremely important, because the maximum intensification and recovery factor depend on it. At the stage of water flood system design we should take into consideration all known geological features. Due to the fact that the values of the geological characteristics of the major oil fields have a wide range and distributed locally, the scheme of injection and production wells pattern on the selected areas within the field has to be different. This should be considered in future for planning of geological and technical operations.
