The characterization of crude being physical, elemental, compositional and bulk parameter analyses is an investigative approach into the properties of crude oil. This study shows the properties of Afiesere crude oil in the Niger Delta area of Nigeria. The parameters investigated are density, specific gravity, API gravity, vapour pressure, kinematic viscosity, moisture content, gum content, cloud point, pour point, flash point, metallic constituents (V, Ni), elemental (N2,O2,S2) and compositional (aliphatic and heavier) hydrocarbons using ASTM/IP procedural methods. The results show density (0.9440 g/cm3), specific gravity (0.9450), API gravity (18.2°), vapour pressure (7 kPa), kinematic viscosity (80.4 cSt), moisture (3175 ppm), gum content (71,000 ppm), cloud point (-2°C), pour point (-10°C), flash point (95°C), Vanadium (0.05 ppm), Nickel (0.39 ppm), N2 (0.11%), O2 (<0.5%), S2 (1.25%), aliphatic hydrocarbons (0.032-2.804%), heavier hydrocarbons (0.210-1.737%). The outcome of these results can be used effectively to predict the transportation, storage and/or refining of the crude oil being analysed.
