Abstract
A method of enhancing recovery of hydrocarbons from a formation includes providing a carbonated fluid, reacting a first salt solution with a second salt solution to provide heat, displacing carbon dioxide from the carbonated fluid, sweeping the formation with the displaced carbon dioxide, mixing the displaced carbon dioxide with at least a portion of the hydrocarbons in the vertical regions, thereby producing a mixture, and producing the mixture via a production well in the formation, thereby enhancing recovery of the hydrocarbons from the formation. A system for controlling the release of carbon dioxide from carbonated water and enhancing oil recovery from a hydrocarbon bearing formation includes an injection system in fluid communication with an injection well that is in fluid communication with a production well via a hydraulic connection.
