Development of a Method for Injecting Water Into a Reservoir to Maintain Reservoir Pressure in an Oil Field

This article discusses a system for developing an oil reservoir using the pressure of regional waters. The system is used for reservoir-type oil deposits with natural water pressure or active elastic water pressure regime. It involves drilling out the deposit with production wells, locating them mainly in the purely oil part of the deposit in closed (“circular”) rows parallel to the internal oil-bearing contour. This includes oil deposits with effective reduced wear regimes of deposits with water-pressure and active elastic-water-pressure regimes. Waterflooding cannot be developed when the permeability of the formations is low. As a result, some deposits are being developed under modern conditions.
