ABSTRACT
The use of conventional (primary and secondary) recovery mechanism is able to recover only about 30% of the oil initially in place leaving behind over 70% of the oil still trapped in the reservoir. The use of chemical (alkaline, surfactant, polymer) flooding has proven to significantly improve the oil recovered from the reservoir. This experiment aims at estimating and comparing the recovery of chemical slugs in the recovery of medium oil and heavy oil. Guar Gum and Gum Arabic are used as the polymers in this project. Tween-80 was used as the surfactant while the Alkaline used was Sodium Hydroxide. Twelve experiments were carried out using various chemical slugs (polymer, surfactant-polymer and the alkaline-surfactant-polymer slug) It was proven from this work that Guar Gum is a better viscosifier than the Gum Arabic and when it combined with Tween-80 to form an SP slug, it yielded the highest recovery than that of any other chemical slug.
