UNISIM-IV: Overview
UNISIM-IV is an open-source benchmark with geological and operational characteristics of Brazilian pre-salt fields, consisting of a light-oil carbonate reservoir with high CO2 content.
The benchmark is divided into four different cases (UNISIM-IV-2019, UNISIM-IV-2022, UNISIM-IV-2024, and UNISIM-IV-2026). The differences relate mainly to the stage of the field’s life cycle and period of production history.
The provided data include: (1) a set of prior uncertainties for probabilistic studies, (2) production, injection, and history data, and (3) a simulation model suggested as a base case or in nominal approaches.
