Resumo: | Nearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after conventional recovery methods have been exhausted and much of this volume would be recovered by Enhanced Oil Recovery (EOR) methods. The in-situ combustion (ISC) is an EOR method in which an oxygen-containing gas is injected into a reservoir where it reacts with the crude oil to create a high-temperature combustion front that is propagated through the reservoir. The High Pressure Air Injection (HPAI) method is a particular denomination of the air injection process applied in light oil reservoirs, for which the combustion reactions are dominant between 150 and 300°C and the generation of flue gas is the main factor to the oil displacement. A simulation model of a homogeneous reservoir was built to study, which was initially undergone to primary production, for 3 years, next by a waterflooding process for 21 more years. At this point, with the mature condition established into the reservoir, three variations of this model were selected, according to the recovery factors (RF) reached, for study the in-situ combustion (HPAI) technique. Next to this, a sensitivity analysis on the RF of characteristic operational parameters of the method was carried out: air injection rate per well, oxygen concentration into the injected gas, patterns of air injection and wells perforations configuration. This analysis, for 10 more years of production time, was performed with assistance of the central composite design. The reservoir behavior and the impacts of chemical reactions parameters and of reservoir particularities on the RF were also evaluated. An economic analysis and a study to maximize the RF of the process were also carried out. The simulation runs were performed in the simulator of thermal processes in reservoirs STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator) from CMG (Computer Modelling Group). The results showed the incremental RF were small and the net present value (NPV) is affected by high initial investments to compress the air. It was noticed that the adoption of high oxygen concentration into the injected gas and of the five spot pattern tends to improve the RF, and the wells perforations configuration has more influence with the increase of the oil thickness. Simulated cases relating to the reservoir particularities showed that smaller residual oil saturations to gas lead to greater RF and the presence of heterogeneities results in important variations on the RF and on the production curves |

A combustão in-situ (CIS) é um método de recuperação avançada de petróleo no qual um gás que contém oxigênio é injetado no reservatório onde reage com o óleo cru para criar uma frente de combustão de alta temperatura que se propaga pelo reservatório. O método HPAI (High Pressure Air Injection) é uma denominação particular do processo de injeção de ar aplicado em reservatórios de óleos leves, onde as reações de combustão são dominantes entre 150 e 300°C e a geração de flue gas é o principal fator de deslocamento do óleo. Um modelo de simulação de fluxo de um reservatório homogêneo foi construído para o estudo, o qual foi inicialmente submetido à produção primária, por 3 anos, e em seguida, ao processo de injeção de água por mais 21 anos. Nesse ponto, com a condição madura estabelecida no reservatório, foram selecionadas três variações desse modelo, de acordo com o fator de recuperação (FR) obtido, para o estudo da técnica de combustão in-situ (HPAI). Em seguida realizou-se uma análise de sensibilidade sobre o FR de parâmetros operacionais próprios do método: vazão de injeção de ar por poço, concentração de oxigênio no gás injetado, esquema de injeção de ar e configuração dos canhoneados dos poços. Essa análise, para um período adicional de até 10 anos produção, foi efetuada com o auxílio da técnica de planejamento composto central. O comportamento do reservatório e os impactos de parâmetros envolvendo as reações químicas e de particularidades de reservatório sobre o FR também foram avaliados. Adicionalmente foram elaborados uma análise econômica e um estudo de maximização do FR do processo. As simulações foram realizadas com o simulador de processos térmicos em reservatórios STARS (Steam, Thermal and Advanced Process Reservoir Simulation) da CMG (Computer Modelling Group). Os resultados mostraram que os FR incrementais foram baixos e que o valor presente líquido (VPL) é impactado negativamente pelos elevados investimentos iniciais para compressão do ar. Observou-se que a adoção de maiores concentrações de oxigênio no gás injetado e do esquema de injeção de ar tipo five spot tende a favorecer o FR, e que a configuração dos canhoneados dos poços apresenta influência crescente com o aumento da espessura porosa com óleo do reservatório. Casos simulados referentes às particularidades de reservatório indicaram que menores saturações residuais de óleo ao gás levam a FR maiores e que a existência de heterogeneidades resulta em variações consideráveis nos FR e nas curvas de produçãoapplication/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-Graduação em Ciência e Engenharia do PetróleoUFRNBRPesquisa e Desenvolvimento em Ciência e Engenharia de PetróleoCombustão in-situ.
