Applying the Buckley-Leverett theory, presents the results obtained in the secondary recovery of reservoir Basal Tena in the Palo Azul field operated by EP PETROECUADOR. The main objective was to determine the increase of the oil recovery factor in the reservoir Basal Tena by Buckley-Leverett calculation. The study process is constituted: first step, the study area must have continuity the reservoir. Second step, pressure decline analysis in the producing wells of the northern sector of the reservoir Basal Tena, resulting that the main production mechanism is the expansion of rock and fluid. The third step was the development of the Buckley-Leverett theory, determined with the injection of water a recovery factor of 14%, which is 3.5 million barrels of oil. The work concludes that the injection of water has an effect in increasing the recovery factor with respect to the remaining reserves by 4.55%.

Keywords : water injection; improved oil recovery; recovery factor.
