For highly paraffinic crudes this factor is 12-5-13-0, while for aromatic or naphthenic crude-oil fractions its value is Crude oil contains organic compounds, heteroatom compounds (S,N,O), hydrocarbons (C, H), metals and organic (Ni, V, Fe) and inorganic (Na +, Ca ++, Cl-) compounds as listed in Figure 1.7. Compounds that contain only elements of carbon and hydrogen are called hydrocarbons and constitute the largest group of organic compounds found in petroleum. Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum. However, raw petroleum or crude oil has characteristic properties and composition.

In the study of water-in-oil emulsions, it is important to know the structure and properties of the crude oil components, their tendency to associate and accumulate  Table 2: Elemental composition of an average crude oil sample by weight .

Crude Oil Benchmarks • A benchmark crude or marker crude is a crude oil that serves as a reference price for buyers and sellers of crude oil. • There are three primary benchmarks,West Texas Intermediaries(WTI),Brent Blend and Dubai Crude.

6. Composition of Crude Oil  Old-deep oils tend to have the lowest viscosity, density, and sulfur content of the four groups. Note that oils vary not only with age and depth, but also withvariations in their source rock and the degree of degradation to which they havebeen subjected. Characteristics of Crude Oil •The hydrocarbons in crude oil can generally be divided into four categories: •Paraffins: These can make up 15 to 60% of crude. •Paraffins are the desired content in crude and what are used to make fuels. •The shorter the paraffins are, the lighter the crude is. •Napthenes: These can make up 30 to 60% of crude. the quality of petroleum products and crude oils. The API gravity is defined as Crude Oils API = 10 – 50, crude oils can generally be classified according to API as shown The definition of specific gravity for gases is somewhat different. The specific gravity of a The naphthenes (or cycloparaffins) are highly bonded, high molecular weight hydrocarbons. All crude oils contain some appreciable amount of the naphthene compounds, (10% by composition). Crude oils also contain a great variety of heteroatomic chemical constituents, comprising of crude oil. Crude Oil means all kinds of hydrocarbons in liquid form in their natural state or obtained by Natural Gas by condensation or extraction. It is a hydrocarbon mixture having simple to most complex structures such as resins, asphaltenes etc.

Crude oil is a naturally occurring, unrefined petroleum product composed of can vary in color from black to yellow depending on its hydrocarbon composition.

The naphthenes (or cycloparaffins) are highly bonded, high molecular weight hydrocarbons. All crude oils contain some appreciable amount of the naphthene compounds, (10% by composition). Crude oils also contain a great variety of heteroatomic chemical constituents, comprising of crude oil.
