RESUMO:

The petroleum industry companies are looking for new technologies that can increase the oil recovery factor contained in their reservoirs. These investments are mainly intended to increase the economic return of oil production projects, which are high. Steam injection is one such advanced methods of recovery, in which steam is injected into the reservoir in order to reduce the viscosity of the oil and make it more mobile. The assisted gravity drainage process steam (SAGD) consists in a method using steam injection in its mechanism, as well as two parallel horizontal wells. In this process, steam is injected through the horizontal injector well, then a steam chamber is formed in the reservoir and heating the oil by the action of gravitational forces, this oil is drained Down where the production well. These analyzes numerical simulations were performed using the thermal simulator CMG STARS (Computer Modelling Group). In this context, this study aimed to carry out a study of different well configurations in the SAGD process, considering the effects of load loss and heat in the injection well in the Brazilian northeast reservoirs. A statistical design was used to investigate the influence of the parameters studied in the recovery factor. It was also carried out technical and economic analysis of configurations of injection wells in order to analyze the profitability of the projects studied. The results showed that the losses in the injector well have a significant influence on the SAGD process. It was also observed that replacement of the horizontal injection well for some steam rates, an increase in the cumulative oil production and makes the application feasible to be applied considering economic factors. The W-SAGD configuration for injection flowrates from 100 tons / day, led to the formation of a vapor chamber larger and more efficient and, finally, the inclined injection wells had a lower production compared to the standard configuration.
