Creation of benchmark cases used worldwide UNISIM-I Benchmark (UNISIM, 2013)
• Carbonate Reservoirs*
• Fractured Reservoirs Simulation*
• WAG, CO2, Treatment Fluid*
• Polymer Flooding*
• Model Based Decision Analysis
• Intelligent fields
• Value of Information

UNISIM-II Benchmark (UNISIM, 2016)
• Pre-Salt Carbonate Reservoirs
– Representation of Critical Heterogeneities in reservoir simulation models
– Fluid Treatment
– Optimization of WAG and CO2 injection
– Importance of models in the decision of: design – G1 (well spacing, prod system, ..); control – G2 (cycles, rates, …)
– Consequences on the performance of the filed under uncertainties (risk analysis)
