ABSTRACT: Crude oils from different geological location have always differed from one another and this has been a pillar statement in the oil and gas industry. Crude found in same geographical region (Niger Delta region) share some varying behavior relative to each other. This study investigates the relationship between specific gravity and kinematic viscosity of the crude oil samples in selected Nigerian oilfields. Results obtained from using ASTM D 1298 and ASTM D 445 in determining the relationship between specific gravity and kinematic viscosity of the crude oil samples in the selected Nigerian oilfields shows that an increase in API gravity records lower kinematic viscosity and vice versa. The Kinematic viscosity decreases with an increase in temperature and an increase in specific gravity shows an increase in mean average boiling point since an increase in specific gravity increases the molecular weight. The result of this work has demonstrated and laid a clear understanding of the relationship between chemical properties such as boiling points, specific gravity and kinematic viscosity.
