The development of formulations that solve at least two problems simultaneously (called multifunction or combo formulations) is very useful. In this study, different formulations were prepared in an attempt to find one that could act at the same time to inhibit deposition of waxes and asphaltenes. Formulations were prepared containing EVA 33 and one of the additives for asphaltenes dispersion (dodecylbenzenesulfonic acid, cardanol and two commercial products called INH1 and INH2), at various

Nevertheless, the EVA33 affected slightly the performance of the asphaltenes stabilizers. The formulations containing cardanol and EVA 33 performed better at inhibiting deposition of both asphaltenes and waxes than the other formulations did.
