A full analysis of the problem of coupling two independent industrial simulators, a reservoir simulator and a steady-state network simulator, has been performed. A classification of the industrial needs has been obtained from the examination of several actual cases studies (fields at development, or production stage, requiring performance optimization through short to long term forecasts). Several coupling configurations and specific requirements, for both reservoir and surface software, have been identified to satisfy the industrial needs. Various commercial solutions have been screened to evaluate the adequacy between the software functional capacities and the identified configurations and requirements. Limitations have been brought to evidence.

The paper, issued from the work of a multidisciplinary team, presents the details of each step described briefly here above. Practical solutions for improving coupled solutions, i.e. to go beyond the identified limitations and to reduce the elapsed times of the coupled simulations, are provided. An improved mutual understanding of the needs of each discipline concerned by the integration of reservoir and surface has been experienced as essential for a successful integrated approach of field optimization. It is intended in the paper to contribute to a better communication between the various upstream petroleum skills: reservoir, production, surface and process engineers.
