Carbonate oil reservoirs hold significant quantities of the world oil and gas reserves. The presence of multiscale heterogeneities leads to a lot of challenges for a precise formation evaluation. The construction of simulation models considering geological carbonate heterogeneities, such as fractures and vugs, remains a challenge. The study of methods for decrease simulation time consumption is also a modern challenge in the development of Brazilian Pre-salt fields.
The research line of Integration with Reservoir Characterization has the purpose of develop, apply and evaluate methodologies to represent critical heterogeneities in reservoir simulation, from geomodeling to reservoir simulation steps, based in the development of carbonate reservoirs. The main goals of this research are (1) study the impact of represent the multiscale heterogeneities in reservoir simulation, (2) study upscaling procedures in complex reservoirs, mainly fractured reservoirs, (3) apply uncertainty analysis in order to study critical parameters in the development of carbonate reservoirs and, (4) study numerical control parameters for decrease computational time consumption.
