One of the most important tasks in Petroleum Engineering is the characterization of the properties of the reservoirs for the application of the method that will bring a greater oil recovery factor. Among the different special recovery methods with great potential for improving the oil recovery factor, the foam injection can be mentioned. The foam may be used as a selective block agent of the reservoir, which reduces the effective permeability zones already swept with high permeability. A widely used tool for this purpose is the simulation of petroleum reservoirs, which through the application of numerical methods allows for the solution of the hydraulic diffusivity equation. This project deals with the computational modeling of foam injection in oil reservoirs using a numerical software. The main objective of this research is to understand which are the parameters that maximize the oil recovery factor when the foam injection is used. Simulation results showed that the main acting parameters for the method of recovery are the oil viscosity and the concentration of surfactant for foam generation. The initial increases in surfactant concentration were that promoted a greater increase in oil production, achieving a recovery above of 30% of oil. Above a certain critical surfactant concentration of about 0.2 lb/stb the production increase was not significant.
