Desta maneira, essa gera??o ? obtida atrav?s de tr?s tipos de processos distintos de acordo com o intervalo de frequ?ncias utilizado. S?o eles: o aquecimento eletromagn?tico indutivo, o resistivo e o diel?trico, tamb?m conhecido como por radia??o. O presente estudo foi baseado em simula??es computacionais em reservat?rios de petr?leo com caracter?sticas similares aos encontrados nas bacias sedimentares do Nordeste brasileiro. Todos os casos estudados foram simulados usando o programa STARS, da CMG (Computer Group, Modelagem vers?o 2012.10). Algumas simula??es levaram em considera??o a inser??o de part?culas eletricamente sens?veis em determinados setores do modelo de reservat?rio estudado atrav?s de fraturas. A proposta deste trabalho ? a utiliza??o do aquecimento eletromagn?tico por indu??o como m?todo de recupera??o de ?leos pesados, para verificar a influ?ncia dessas part?culas acima citadas no modelo de reservat?rio utilizado. Foram feitas an?lises comparativas envolvendo o aquecimento eletromagn?tico indutivo, a opera??o do fraturamento hidr?ulico e a inje??o de ?gua em diferentes situa??es do modelo de reservat?rio estudado. Foi constatado que fraturando o po?o injetor com o intuito de que o aquecimento eletromagn?tico ocorra no mesmo po?o em que h? a inje??o de ?gua, houve um acr?scimo consider?vel do fator de recupera??o e produ??o acumulada de ?leo em rela??o aos modelos em que o fraturamento hidr?ulico ocorria no po?o produtor e a inje??o de ?gua no po?o injetor. Este fato se deve ? gera??o de vapor in situ no reservat?rio. / The success achieved by thermal methods of recovery, in heavy oils, prompted the emergence of studies on the use of electromagnetic waves as heat generating sources in oil reservoirs. Thus, this generation is achieved by three types of different processes according to the frequency range used. They are: the electromagnetic induction heating, the resistive and the dielectric, also known as radiation. This study was based on computer simulations in oil reservoirs with characteristics similar to those found in the sedimentary basins of the Brazilian Northeast. All cases studied were simulated using the software STARS, CMG (Computer Group, version 2012.10 Modeling). Some simulations took into account the inclusion of electrically sensitive particles in certain sectors of the reservoir model studied by fracturing. The purpose of this work is the use of the electromagnetic induction heating as a recovery method of heavy oil, to check the influence of these aforementioned particles on the reservoir model used. Comparative analyses were made involving electromagnetic induction heating, the operation of hydraulic fracturing and the injection of water to the different situations of the reservoir model studied. It was found that fracturing the injection well in order that the electromagnetic heating occurs in the same well where there is water injection, there was a considerable increase in the recovery factor and in the cumulative oil production in relation to the models in which hydraulic fracturing occurred in the production well and water injection in the injection well. This is due to the generation of steam in situ in the reservoir.
