S4  Ciências e Engenharia do Petróleo    Titulo: PROCEDIMENTOS E RESULTADOS DO PROCESSO DE MUDANÇA DE ESCALA DO RESERVATÓRIO BURACICA/SERGI/ZONAS 2 - 6   Resumo : WE PRESENT THE METHODS AND RESULTS OF THE UPSCALING PROCESS APPLIED TO THE BURACICA FIELD, SERGI FORMATION, ZONES 2-6, OIL RESERVOIR. RESERVOIR STUDIES USE TWO KINDS OF GRIDS: A FINE ONE TO DESCRIBE THE GEOLOGIC HETEROGENEITIES, USUALLY BUILT WITH THE AID OF GEO-ESTATISTICAL METHODS; AND A COARSER ONE FOR FLUID FLOW SIMULATION. UPSCALING ROCK PROPERTIES FROM THE FINE TO THE COARSE GRID IS A CRITICAL TASK: THERE IS A RISK OF LOOSING IMPORTANT AND HIGH-COST INFORMATION IN THE PROCESS. THIS WORK SHOWS A METHODOLOGY OF UPSCALING OF PETROPHYSICAL PROPERTIES (POROSITY, ABSOLUTE PERMEABILITY AND RELATIVE PERMEABILITY FROM LOGGING AND CORE DATA TO THE FLOW SIMULATION GRIDBLOCKS. WE USED THE PROGRAM UPA, DEVELOPED BY PETROBRAS, THAT COMBINES SEVERAL UPSCALING COMPUTING METHODS AND FACILITIES. KEYWORDS: UPSCALING, FLOW SIMULATION, GEOESTATISTICS, RESERVOIR, PERMEABILITY     Autores : Machado, Augusto André Vieira Mota, Rosane Oliveira Romeu, Regis Kruel Saldanha Filho, Paulo Carlos 0     Trabalho Completo :   COBEM99 | Comissão  Organizadora | Palestras | Sessões Técnicas | Autor | Simpósios e Sessões Especiais | Revisores |  Título  dos  Trabalhos | Local
