A production allocation framework for natural gas production systems

Abstract Production planning in upstream natural gas production systems is a unique challenge due to the multiproduct network, nonlinear pressure-flowrate relationships in the wells and the trunkline network, and production-sharing contracts (PSC) and operational rules. A nonconvex mixed-integer nonlinear programming (MINLP) model of the upstream production system including all the features described above is formulated and applied to a real-world case study in Malaysia. The model is solved with GAMS/BARON and a hierarchical multiobjective case study is presented.
