US 2008/0173440 A1 · SYSTEM FOR INJECTING WATER, COLLECTED FROM A SUBTERRANEAN AQUIFER, INTO AN OIL RESERVOIR

Abstract

The invention relates to a system for collecting and injecting water from a subterranean aquifer directly into hydrocarbon reservoirs. The system may include a collecting wells in aquifers, injection wells in hydrocarbon producing reservoirs and a hydraulic connection for pumping water with access to a collecting zone and to an injection zone. The invention is applicable to hydrocarbons production fields, where water injection is used to maintain the pressure in a hydrocarbon producing reservoir, thereby enhancing the recovery rate of the same.
