Abstract
Methods and systems are provided for allocating production among reservoir compartments by way of compositional and isotopic analysis. That is, where individual reservoir compartments contribute differing amounts of fluid to a commingled production stream, the methods herein determine the relative contribution of fluid volume from each reservoir compartment. Both a composition-based relative contribution and an isotope-based relative contribution of fluid from each reservoir compartment may be determined to allocate production to each reservoir compartment, the determinations respectively being based on composition mass balances and stable carbon isotope mass balances of components. The combination of both allocation analysis provides quality checks on the results that identify improper allocations that may arise. In addition to production allocation, other applications include, among others, determining the effectiveness of intervention operations and providing feedback for adjusting operations. Advantages include lower costs, higher accuracies, and ease of use as compared to conventional methods.
