RESUMO

Steam injection is one of the most widely used techniques in the word for heavy oil recovery. The scope of this work refers to the proposition of an experimental apparatus for studying this technique. The apparatus is detailed, with emphasis on its major components, such as: steam generator, steam quality control and the injection prototypes: a tube to study the steam flooding process, and a cell to study the steam assisted gravity drainage (SAGD) method. Based on the experimental models, numerical models are created and a series of simulation runs is carried out to predict the models behavior for different values of rock and fluid properties. The simulation tests are useful to identify the parameters range for the proper functioning of apparatus, the oil production curves behavior, the pressure and temperature profiles over time, to estimate the residual oil saturation and to predict the steam chamber expansion dynamics inside the injection models
