What is heavy oil properties
Heavy Oil Properties Heavy oils display a high content of high molecular weight hydrocarbons and elevated levels of heterocompounds including sulfur, nitrogen, oxygen and metals (Speight, 1991). Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Physical properties that differ between heavy crude oils and lighter grades include higher viscosity and specific gravity, as well as heavier molecular composition. While heavy oil is abundant, it also presents significant economic and technological challenges. Although it is an important energy resource, heavy oil requires an unusually high level of effort and expertise to economically develop and produce. Production rates of this high viscosity, often chemically compromised hydrocarbon are influenced by Heavy Oils – Seismic Properties Michael Batzle*, Brian Zadler, Ronny Hofmann, Colorado School of Mines De-hua Han, University of Houston Summary Heavy oil properties are strongly dependent on composition and temperature. Because of biodegradation, alkanes are destroyed and complex heavy compounds dominate. As a Heavy-oil reservoirs are of minor interest during pressure depletion because they typically yield only marginal amounts of oil because of their low dissolved-gas contents and high fluid viscosities. The distinguishing characteristic between volatile and black oils is the stock-tank-oil content of their equilibrium gases. Crude's classification as either “light” or “heavy” depends on the oil’s relative density, based on the American Petroleum Institute (API) Gravity. This measurement reflects how light or heavy a crude oil is compared to water. If an oil’s API Gravity is greater than 10, it is lighter than water and will float on it. Toxicity of Bakken Crude Oil. •Toxicity is the degree to which a substance can damage an organism. •Toxicity can refer to the effect on a whole organism, such as a human, •It can also be the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
Heavy crude oil is highly-viscous oil that cannot easily flow to production wells under normal Physical properties that differ between heavy crude oils and lighter grades include Natural bitumen and extra-heavy oil differ in the degree by which they have been degraded from the original conventional oils by bacteria .
Heavy Oil is a form of unconventional oil that is thick and highly viscous, and therefore sulfur and metals such as vanadium and nickel, which all increase its density. and viscosity, special extraction methods are needed to recover heavy oil The measurement that we care most about today is viscosity since that is the property which governs well productivity. Viscosity is not synonymous with Gravity. At the molecular level, crude oil is composed predominantly of carbon, which can Crude oil is also classified based on physical characteristics and chemical This measurement reflects how light or heavy a crude oil is compared to water. Crude oil, liquid petroleum that is found accumulated in various porous rock variety of complex molecular structures, some of which cannot be readily identified. but they also form some of the heavy asphaltlike residues of refinery processes. varying constituents and proportions, its physical properties also vary widely. Extra-heavy crude oil: API gravity below 10 °API (higher than 1000 kg/m³). The API degrees indicate whether a crude oil floats on water or sinks. Light crude oils When it comes to general properties, heavy crude is thicker, more resistant to output, which reduces the energy returned on energy invested (EROEI) ratio.

Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Physical properties that differ between heavy crude oils and lighter grades include higher viscosity and specific gravity, as well as heavier molecular composition. The major properties of heavy fuel oil are as follows; 1. Density: Density is the relationship between mass and volume at a stated temperature, and the SI unit is Kg/m 3 . This gives value of 800- 1010 kg/m 3 for marine heavy fuel oil. Heavy Fuel Oil HFO, also known as “residual fuel oil”, is based on the high viscosity, tar-like mass, which remains after the distillation and subsequent cracking of crude oil in order to produce lighter hydrocarbon products, such as petrol, distillate diesel fuels and heating oil or feedstocks for lubricants. Heavy oil is a type of crude oil which is very viscous, meaning that it does not flow easily. The common characteristic properties of heavy oil are: high specific gravity, low hydrogen to carbon ratios, high carbon residues, and high contents of asphaltenes, heavy metal, sulphur and nitrogen. Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is made between heavy oil and oil sands (tar sands), although the criteria of less than 12°API gravity and greater than 10,000 cp are sometimes used to define oil sands.
They are classified and named according to their viscosity, IFO 180 and IFO 380, In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a which is no longer referred to as an HFO, as its proportion of heavy fuel oil is Thus, the characteristics of a certain intermediate or heavy fuel oil will depend on the properties of the crude oil(s) from which the residue is derived, as well as the is a very important property for the heavy products obtained from the crude oil. The viscosity their dominance or reduction in various refinery products is what is. Together with heavy fuel oil, it is the most important liquid fuel for industrial kinematic viscosity of less than 6 mm²/s at 20°C. It is closely related to other light oil at which it must still be possible to filter the fuel (depending on the cloud point). Light crude oil contains a significant amount of natural gas liquids, whereas heavy crude oil has little or no natural gas liquids and the lowest temperature at which the liquid will flow just before it becomes solid.
