A software tool is described that enables optimization for maximizing asset value, both with and without uncertainty. Modular architecture allows examination of different objective functions, optimization schemes and financial models. The method generates an efficient frontier that can be used for risk and decision analysis. The tool is demonstrated in the context of a field example optimizing for Net Present Value (NPV). Valuation of advanced completions is explored along with the returns gained from expanding surface gas handling facilities. The results clearly demonstrate the utility of such a tool for value-maximization in planning both near and long-term time horizons as well as providing the necessary foundation for maximizing asset value.
