Abstract: System and methods for creating a visual interpretation of the amount of flow between injection and production wells in a hydrocarbon field at any instant in time. Using conventional reservoir simulation input, streamlines are first generated using a streamline-based flow simulator. The streamlines are then used to determine well pairs and the volumetric flow rate associated with each well in the pair. The fraction of the flow rates in the well pair to the total flow rates of each well are then calculated. These fractions are also known as well allocation factors. After placing the well locations on a multi-dimensional map, the well allocation factors are represented by a multi-dimensional, multi-color stick map connecting each well pair.
