Abstract: The present disclosure provides techniques for inline injection of water and chemicals for a dump flood. The techniques include collecting water from a source reservoir into a water collection zone of an adjacent water injection well, and injecting a chemical solution into the water injection well. The water and the chemical solution are then mixed downhole in a mixer, such as a static mixer. The mixed injection fluid is then directly injected into an adjacent target reservoir.
