Abstract: This involved the formulation of organic film forming inhibitor that is intended to be used in control of corrosion in petroleum oil field environment. Preliminary investigation was carried out as a means of range finding by manually varying the concentrations of the components of the inhibitor. The obtained percentage concentrations ranges were optimized using design expert version 7.0. The experimental design method used was Mixture Design Techniques (D-Optimal method). This was used to determine the optimum concentration of the components in the inhibitor formulation. The combined therapy of formulation D gave performance with efficiency of 99.92% followed by formulation C with efficiency of 99.70%. The other formulations A and B also gave efficiency of 99.685 and 99.69 respectively with the different values of octadecylamine and imidazoline concentration. The best optimum performance is that of formulation D containing 18.41% octadecylamine, 24.15% of imidazoline, 1.27% surfactant, 0.4% demulsifier, 1.4% inorganic synergy 1.24% co-solvent and 52.3 solvent.
