Este m?todo consiste na queima parcial do ?leo in situ, cujo objetivo ? gerar uma frente de combust?o que ajude no movimento do ?leo. Essa frente de combust?o aquece as zonas pr?ximas, logrando a redu??o da viscosidade do ?leo e permitindo o seu deslocamento at? o po?o produtor. Apesar de parecer um processo f?cil, a combust?o in situ engloba uma s?rie de mecanismos complexos que mesmo na atualidade a torna dif?cil de representar atrav?s de modelos anal?ticos, f?sicos e de simula??o num?rica. O objetivo do trabalho ? analisar e determinar os par?metros que t?m influ?ncia no processo, destacando a cin?tica (energia de ativa??o, coeficiente de Arrhenius e porcentagem de craqueamento para a produ??o de coque durante o processo) de tr?s diferentes modelos de rea??es qu?micas e da vaz?o de inje??o do ar. Para verificar a aplicabilidade do processo no Brasil foi realizado um estudo de simula??o em reservat?rios de ?leo pesado com caracter?sticas do Nordeste Brasileiro. As simula??es foram realizadas utilizando o m?dulo ?STARS? da ?Computer Modelling Group?, com o objetivo de realizar estudos de m?todos de recupera??o avan?ada de ?leo. Dentre todos os par?metros analisados, a energia de ativa??o-fator pr?-exponencial apresentou a maior influ?ncia, ou seja, quanto menor o valor da energia de ativa??o-fator pr?-exponencial maior a fra??o de ?leo recuperada. A porcentagem de craqueamento mostrou uma forte influ?ncia no processo, devido a que enquanto menor for a quantidade de coque formado maior ? volume de ?leo recuperado. / In situ Combustion (CIS) is the oldest thermal method of oil recovery. This method consists of partial combustion of in situ oil, its goal is to generate a combustion front that helps to move the oil. This combustion front will heat the surrounding areas, achieving a reduction in oil viscosity and allowing its displacement into the production well. It may seem a simple process, however in situ combustion involves a series of complex mechanisms that difficult until today its representation through analytical models, physical models and numerical simulation. The aim of this investigation is to analyze and determine the parameters that influence the process, highlighting the kinetics of the process (activation energy, Arrhenius coefficient and percentage of cracking for the production of coke) three different models of chemical reactions and the air injection rate. To verify the applicability of the process in Brazil a simulation study was conducted in heavy oil reservoirs with characteristics of the Brazilian Northeast. The simulations were performed using the "STARS" module from the "Computer Modelling Group", which objective is to study methods of enhanced oil recovery. Among all the analyzed parameters, the activation energy-pre-exponential factor showed the greatest influence, that is, the lower the value of the activation energy-preexponential factor the higher the fraction of oil recovery. The cracking percentage also showed a strong influence in the process, the smaller the amount of coke formed the larger volume of oil recovery.
