Benchmarking commercial multiphase flow simulators in pre-salt offshore production facilities

Abstract This study benchmarks the predictive performance of commercial multiphase flow simulators for flow assurance in Brazilian pre-salt offshore production facilities (OPFs). A dataset of 350 field measurements from seven OPFs was used to compare ALFAsim and OLGA against the in-house mechanistic model Parque das Baleias (PB), under identical geometry, fluid property, and boundary condition inputs. Steady-state simulations evaluated pressure, temperature, and liquid holdup, while transient ca
