• Resumen

  • Research on short-term steady-sate production optimization of oilfelds led to the development of models and solution methods, several of which have found their way into practice. Early models considered satellite wells that operate with a fxed topside pressure and gas-lift injection, while recent approaches address distinct types of artifcial lifting, pressure control, and processing equipment. By integrating existing approaches, this work presents a fexible model for production optimization that considers new features, including fow assurance constraints and smart selection of artifcial lifting operating modes (gas-lift with multiple valves, electrical submersible pumping, and dual completion). Given that the proposed model is conceptual, piecewise-linear functions are obtained from feld and simulation process data to approximate nonlinear relations. This way, the methodology decides the best combinations of routing and operation modes to maximize production gains. Simulated results are reported considering a representative asset that illustrates complex behavior.
