Abstract: A method and system provide automated mapping of fluid distributions in an oil field reservoir. The processes include receiving initial fluid and pressure characteristics of well-pairs in the field. Measurements from sensors detect the amount of fluid injection versus fluid produced for the well-pair during a timestep. The remaining fluid volume for the well-pair may be determined. In an exemplary embodiment, a grid map of well-pairs in the oil field are automatically generated which shows in real-time the remaining volume of fluid for each well-pair in the map. A user may thus manage the production from the oil field with increased efficiency based on the improved accuracy of the mapped data.
