Abstract: Crude oil is a naturally occurring, yellowish-black liquid found in geological formation beneath the earth’s surface.Crude oil is a complex mixture made up of hydrocarbons which mainly consist of carbon (C) and hydrogen (H) along withheteroatomic chemical constituents, comprising of sulphur, oxygen, nitrogen and metals such as Vanadium, nickel, iron andcopper. Crude oil is characterized by some chemical and physical properties which play important role in oil field. In theexploration and production of crude oil, these properties are of paramount importance in decision making during productionand transportation of Crude oil. In this paper, important physicochemical properties of Crude oil collected from Westernonshore field of India were studied. The parameters such as Water content, Density, Specific gravity, API gravity, Pour point,Distillation, Asphaltene content, Wax content, Melting and Congealing point of Wax and Smoke point have been studied.Keywords: Crude oil, Pour Point, Wax & Asphaltene
