Résumé

Several techniques have been used to increase the mobility of crude oil. This work aims to study the concentration effect of the poly (ethylene-co-vinyl acetate) (EVA) on the viscosity, the yield stress and the elastic modulus of crude oil. Three types of (EVA) were selected containing 12%, 18% and 25% of vinyl acetate at different temperatures 6.3 °C, 10°C and 40°C. Different concentrations of (EVA) were tested 100, 200, 300, 400 ppm. The results obtained showed that the EVA improve the rheological parameters of crude oil. The results has indicated that the additive efficiency were significantly influenced by the temperature.
