Resumo: | The solvent–steam assisted gravity drainage is an oil recovery process that combines the advantages of thermal and miscible effects, and it has been successfully tested, especially in Canada, where many heavy oil reservoirs are located. This method uses two parallel horizontal wells drilled one above the other, the upper injects steam and solvent and the lower produces oil. This process has not been applied yet in Brazil, where there are heavy oil reservoirs, especially in northeast region. Based on this context, this research aimed to study the application of the ES-SAGD process in a semisynthetic reservoir, with characteristics similar to those found in the Brazilian Northeast, specifically to analyze the influence of the solvent injection scheme on ES-SAGD. Numerical simulations were performed using commercial software from CMG. It was analyzed several steam-solvent injection rates, using two injected temperatures for solvent, (at reservoir or at steam temperature´s), in order to minimize explosion risks, that can be due to high temperatures. Results showed that solvent injection temperature has great influence on oil recovery, it is better for oil production when it is inject hot solvent, because cold solvent generates a cooling of the steam. However, it is possible to injected cold solvent (at reservoir temperature), and increase oil production, changing some steam properties, avoiding explosions risks. |

El drenaje asistido por gravedad con inyección de vapor y disolvente es un proceso de recuperación de petróleo que combina las ventajas de los efectos térmico y miscible, y se ha probado con éxito, especialmente en Canadá, donde se encuentran muchos yacimientos de petróleo pesado. Este método utiliza dos pozos horizontales paralelos perforados uno sobre otro, el superior inyecta vapor y disolvente y el inferior produce petróleo. Este proceso aún no se ha aplicado en Brasil, donde existen yacimientos de petróleo pesado, principalmente en la región nordeste. Motivada por este contexto, esta investigación tuvo como objetivo estudiar la aplicación del proceso ES-SAGD en un reservorio semisintético, con características similares a las encontradas en el Nordeste brasileño, más específicamente analizar la influencia del esquema de inyección de solvente en el ES-SAGD. Las simulaciones numéricas se realizaron con el programa informático comercial CMG. Fueron analizados varios flujos de inyección de vapor y solvente, utilizando dos temperaturas de inyección del solvente, (en el yacimiento o en la temperatura del vapor), con el objetivo de minimizar los riesgos de explosión, que pueden ser debidos a las altas temperaturas. Los resultados mostraron que la temperatura de inyección del disolvente tiene una gran influencia en la recuperación de petróleo, es mejor para la producción de petróleo cuando se inyecta el disolvente caliente, porque el disolvente frío genera un enfriamiento por vapor. Sin embargo, es posible inyectar disolvente frío (a la temperatura del yacimiento), y aumentar la producción de petróleo, cambiando algunas propiedades del vapor, evitando riesgos de explosiones.A drenagem gravitacional assistida com injeção de vapor e solvente é um processo de recuperação de óleo que combina as vantagens dos efeitos térmicos e miscíveis, e tem sido testado com sucesso, especialmente no Canadá, onde estão localizados muitos reservatórios de óleo pesado.

Este processo ainda não foi aplicado no Brasil, onde existem reservatórios de óleo pesado, principalmente na região nordeste. Motivado por este contexto, esta pesquisa objetivou estudar a aplicação do processo ES-SAGD em um reservatório semissintético, com características semelhantes às encontradas no Nordeste brasileiro, mais especificamente analisar a influência do esquema de injeção de solvente no ES-SAGD. Simulações numéricas foram realizadas através do software comercial da CMG. Foram analisadas várias vazões de injeção de vapor-solvente, utilizando duas temperaturas de injeção de solvente, (no reservatório ou na temperatura do vapor), a fim de minimizar os riscos de explosão, que podem ser decorrentes de altas temperaturas. Os resultados mostraram que a temperatura de injeção do solvente tem grande influência na recuperação do óleo, é melhor para a produção de óleo quando se injeta o solvente quente, pois o solvente frio gera um resfriamento do vapor. Porém, é possível injetar solvente frio (na temperatura do reservatório), e aumentar a produção de óleo, alterando algumas propriedades do vapor, evitando riscos de explosões.
