abstract
Dynamic oil and gas production systems simulation and optimization is a research trend with a potential to meet the challenges faced by the international oil and gas industry, as has been already demonstrated in a wide variety of publications in the open literature. The complex two-phase flow in reservoirs and production wells governs fuel transport, but is mostly handled by algebraic approximations in modern optimization applications; the true reservoir state variable profiles (initial/boundary conditions) are not known. Integrated modeling and optimization of oil and gas production systems treats oil reservoirs, wells and surface facilities as a single (yet multiscale) system, focusing on computing accurate reservoir and well state variable profiles, useful for optimization. This paper discusses a strategy for interfacing reservoir simulation (ECLIPSE) with equation-oriented process optimization (gPROMS) and presents a relevant application.
