• Palabra clave: Tensión Interfacial; Sistema N-Alcano/Agua; Temperatura; Given the complexity to find new reserves of hydrocarbons; enhanced oil recovery techniques have a privileged place in the research and implementation of pilot programs in several countries of the world; where the petrophysical properties and the appropriate description of the reservoirs have an important role. In such a way the reduction of parameter of the interfacial tension is essential in the increase the capillary number (viscous forces/capillaries forces) and thus optimize the EOR processes. This work was carried out in the Drop Shape Analyzer DSA100HP equipment; where was proposed three systems n-alkane/water (two with pure fluids and one with sodium chloride) maintaining constant the pressure and gradually increase the temperature; these results are then processed through a statistical analysis obtained values of interfacial tension for each thermal point. In this way the results achieve were three equations that are perfectly adjusted to the literature and which were validated using the comparison with other authors; finding values of angle coefficient whose relative error percentage is entirely satisfactory; similarly was presented a setting optimum to be matched with theoretical values extracted from numerical methods. The results of this study showed that: (1) New correlations that describe the behavior of the interfacial tension to be subjected to the temperature increase; (2) more technical elements to validate the bibliographic sources; and (3) a new methodology for the calculation of the interfacial tension using the technique of pendant drop.
