Api gravity of crude oils
API gravity is one of the key characteristics of crude oil that, along with other characteristics such as sulfur content, is used by refiners when evaluating different crude streams for processing into petroleum products. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula: API = (141.5/Specific Gravity) - 131.5. API gravity of crude oil grades. A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) crude. Generally, lighter (high API) crudes are more valuable because they yield more high-value light products when run through a refinery. Classifications or grades Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3). Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3). Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3). Extra heavy oil has an API Specific Gravity of Crude Oil: They are many common crude types like west Texas, Brent… API gravity is a measure of how light or heavy the crude oil compared to water. The API of crude oils varies typically between 10 and 50, with most crude oils falling in the range of 20-45. Using API gravity, the conventional crude oils can be generally considered as light (°API>30), medium (30>°API>22), and heavy (°API<22).
14 Nov 2019 Most crude oils have API gravity values in the range 10-70 API degrees. The higher the API gravity value, the less dense the crude; the greater
In addition to the API.

The higher the API gravity value, the less dense the crude; the greater Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Extra heavy oil is defined with API gravity below 10.0 °API (API gravity, Specific Gravity. The specific gravity is typically measured using the American Petroleum Institute. (API) standard or the API gravity of the crude oil. The API 25 Feb 2016 A higher APIAmerican Petroleum Institute indicates lighter oil. Fresh water has a gravity of 10° APIAmerican Petroleum Institute. Heavy oils oils because these have low specific gravity, low sulphur contents, low viscosity and oil on the basis of API gravity except one (N) sample which belongs to the
30 Jul 2019 141.5 ÷ .743 – 131.5 = 58.94. With that, we have discovered both the Specific Gravity, and our API Gravity for our particular crude oil sample.
barrels of crude oil per metric ton=1÷[141.5API gravity+131.5×0.159]. Density, specific gravity (SG) and API gravity* values are used to monitor quality during the production of crude oil, and to establish its price in trading. This
Classifications or grades Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3). Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3). Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3). Extra heavy oil has an API
Density, specific gravity (SG) and API gravity* values are used to monitor quality during the production of crude oil, and to establish its price in trading. This Liquids lighter than water, such as oil, have API gravities numerically greater than 10. On the basis of their API gravity, crude oils can be classified…
Extra heavy oil. Also referred to as bitumen, extra heavy crude oils have API gravity of below 10.0 degrees. While these are accurate classifications it’s important to note that exact differentiations between light, medium, heavy and extra heavy will vary depending on the region of origin. At the end of the day,
14 Jan 2011 Crude oils may be divided into Light and Heavy crudes on the basis of their gravity. The API gravity is determined as: °API = 141.5. - 131.5. 30 Jul 2019 141.5 ÷ .743 – 131.5 = 58.94. With that, we have discovered both the Specific Gravity, and our API Gravity for our particular crude oil sample. 20 Feb 2020 API gravity and sulphur content are important determinants of oil quality because heavy oils are harder and more expensive to produce or extract 26 Nov 2019 Crude oil's density is measured using API (American Petroleum Institute) gravity.
