UNISIM-I: Synthetic Model for Reservoir Development and Management Applications

Several methodologies related to reservoir management applications were created recently. Many times, it is difficult to know the applicability of these methodologies when applied in real reservoirs that are unknown. In order to test them, a synthetic model was created (UNISIM-I-R) where the real reservoir is substituted by a reference model with known properties, so methodologies can be tested and compared. The reference model was built in a high resolution geocellular model, using public data from Namorado Field, Campos Basin, Brazil. The level of details is high to ensure that geological model is reliable in order to guarantee derivative suitable models for simulations that honor the used data. In addition, a simulation model with uncertainties (UNISIM-I-D) was created in a medium numerical grid resolution after the upscaling of a geomodel realization with some information of the reference model. The reference and simulation models were then submitted to production and injection scheme to compare the results. The focus of the application was an initial stage of the field management. The comparison between reference and simulation model was done to check the consistency and highlight the differences, using a base production strategy to ensure the quality and reliability of the UNISIM-I-R. The main result of this work is then a model which can be used for future comparative project solutions.
