Abstract - Unconventional oils - mainly heavy oils, extra heavy oils and bitumens - represent a significant refers to crude oils having API gravity lower than 22. 25 Sep 2014 Unconventional oils - mainly heavy oils, extra heavy oils and In fact, significant volumes of heavy oil found in recent discoveries have API 22 Sep 2015 The Petrocedeño project, Zuata field, produces crude oil of 8.3 °API by diluting it with gas and a subsequent upgrading in various refinery units. 19 Jan 2016 Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp 2-Canadian heavy-oil and extra-heavy-oil deposits.

hydrocarbon deposits, such as Canadian oil sands, Venezuelan heavy oils and pipeline due to low API gravity, high viscosity or high pour point. energy in excess of what is required to run the entire upgrading complex (see Table 4:.

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 flow easily and contain more volatile components, while extra-heavy crude oils are highly viscous to nearly tar-like and show a higher density. In the Venezuelan Orinoco heavy oil belt, for example, about 1 bbl of diluent is required for every 3 or 4 bbl of extra-heavy oil. There is no universally accepted definition of what constitutes heavy oil; however, it generally has a high density, with an API of between 10°API and 22°API and a viscosity above 100 cp. Almost all heavy oil is an alteration of products of conventional oil. At an API gravity of 10, crude oil will have the same density as water. Any API below 10 and the crude sinks in water rather than floating. Oils with an API in this range are often called extra heavy oils. It is estimated that there is twice the amount of heavy crude in reserves than light crude. Heavy crude oil (or extra heavy crude oil) is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°.

In extra heavy and heavy crude oil separation (< API 15 Density >960 kg/m 3 (8 lb/gal) and oil sands, the cleaning process is done in separators, FWKO, BOTs and Desalters. It is important to know the density over the entire level to ensure the most time and cost-effective operation.

Oil with a low API gravity density (generally <25°API). Heavy or extra–heavy crude oils as defined by the density ranges given, but with viscosities greater than This article reviews very heavy crude oil supplies, upgrading options and the key role Typical qualities for Venezuelan unconventional crude oils are 5°-15° API It may be difficult for the producer to justify the cost of the additional upgrading The four projects convert the extra-heavy crude from approximately 9° API density crude to lighter, sweeter synthetic crude, known as syncrude (26° API), at the Determine Density and API Gravity in Accordance with ASTM D5002 and ISO 12185 chain lengths of the constituent hydrocarbons and additional components (such as sulfur) and are Know how to measure API of heavy and light crude oil.

Light oil is characterized by an API gravity of at least 22°, and extra-heavy oil has an API gravity of less than 10°. Natural bitumen, also known as oil sands, shares the characteristics of heavy oil but is even more dense and viscous - with a viscosity greater than 10,000 cP.

Extra-heavy oil is that portion of heavy oil having an API gravity of less than 10°. Natural bitumen, also called tar sands or oil sands, shares the attributes of heavy oil but is yet more dense and viscous. The Petrocedeño project, Zuata field, produces crude oil of 8.3 °API by diluting it with gas and Extra heavy oil development requires high energy intake that has a direct impact on the Heavy and Extra Heavy Oil Forum Of all the liquid oil of all types delineated worldwide to date, 70% of it is in the category of <20°API oil in unconsolidated sandstone reservoirs less than 1000 m deep. Approximately 15% is 10-20°API oil, and 55% is <10°API, often called extra-heavy oil or bitumen. Heavy crude oil (or extra heavy crude oil) is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°.

the heavy oils, the API° of which is between 10 and 20 ;. – the extra-heavy oils and bitumen, the API° of which is less than 10 (the “in situ” level of viscosity makes

An API of 10 is equivalent to water, which means any oil with an API above 10 will float on water while any with an API below 10 will sink. The API gravity is used to classify oils as light, medium, heavy, or extra heavy. As the “weight” of an oil is the largest determinant of its market value, API gravity is exceptionally important.
