Abstract:
A method for artificially recharging a target reservoir in a geological formation using powered water injection from a local source aquifer in the geological formation. The method comprises detecting chemical properties of water in the source aquifer, determining whether the water in the source aquifer is compatible with water in the target reservoir based on the chemical properties, activating an electrical submersible pump (ESP) positioned between target reservoir and the source aquifer to inject water from the source aquifer into the target reservoir, detecting downhole pressure, temperature and water flow rate conditions at the ESP, and controlling a rate at which the ESP injects water using the downhole pressure, temperature and water flow rate conditions.
