RESUMO

This work studies the application of strearntube theory joined with a two-porosity linear model in heterogeneous reservoirs under injection of a incompressible wetting fluid and the production of a non-wetting fluid. It was considered that the streamlines are fixed and there is no flow between each channel. Gravity was neglected and the imbibition phenomena was modeled by the use of a mass transfer model. Analytical solutions given by complex potential theory are shown for two well pattem, as well as procedures to obtain the streamlines. The generalized linear model allowed its use in the two-dimensional case. Another item studied was how to obtain a variable diffusion coefficient as a function of saturation from capillary pressure data
