Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. For example, an embodiment of a computer implemented method of analyzing a flood operation on a hydrocarbon reservoir having heavy oil is provided. The embodiment includes, for a first injection well of the hydrocarbon reservoir: receiving injection rate data and production rate data, establishing a plurality of time windows based on breakthrough time of each production well that has broken through until the current date, and running capacitance resistance modeling for each established time window to generate interwell connectivities for each well pair. The embodiment further includes determining a value of injected fluid for the first injection well as a function of time in the future using a continuous function estimated interwell connectivity and an estimated oil-cut value.
