Crude oil api gravity conversion
The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5. Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil. Crude oil with API gravity less than 10° is referred to as extra heavy oil or bitumen. Bitumen derived from oil sands deposits in Alberta, Canada, has an API gravity of around 8°. It can be diluted with lighter hydrocarbons to produce diluted bitumen, which has an API gravity of less than 22.3°, Estimate API Gravity at 60° F: 1) Usually, your API gravity reading will be at a temperature other than 60°F. To convert an API gravity reading to 60°F, we usually use ASTM Table 5B. To convert an API gravity reading to 60°F, we usually use ASTM Table 5B. API sets the standards for oil & gas industry. this article touches on the API gravity number, how it is calculated, the story behind using it, a list of crude oil blends and benchmarks, and the formulas associated with calculating API gravity 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). Note that the relationship between °API and specific gravity is not linear.

4 Feb 2020 The American Petroleum Institute established API gravity as a measure of the density of petroleum liquids relative to water. The greater the API, 3 Nov 2017 Oil density is often reported in terms of API gravity. API gravity can be converted to specific gravity using the API to Specific Gravity Conversion API Gravity, or The American Petroleum Institute gravity, is a measure of how light Density is defined as weight per unit volume by the United States Oil and gas products is necessary for the conversion of measured volumes to volumes at Oil gravity represents the density of the oil at stock tank conditions. The oil The conversion from API gravity (oil field units) to density (kg / m3 (SI units)) is:.

If you need need to convert other value use our online Api Gravity Calculator. 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. Conversion calculator API - specific gravity. API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST - National Institute of Standards and Technology. The measuring scale is calibrated in terms of degrees API. To calculate API Gravity, first measure Crude Oil specific gravity at 16 C⁰ (60 F⁰) then plug the number into the following equation: API gravity = (141.5/Crude Oil Specific Gravity) – 131.5 What is the API Gravity Unit Of Measurement? The API gravity is unitless (as the case with specific gravity).
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

To calculate API Gravity, first measure Crude Oil specific gravity at 16 C⁰ (60 F⁰) then plug the number into the following equation: API gravity = (141.5/Crude Oil Specific Gravity) – 131.5 What is the API Gravity Unit Of Measurement? The API gravity is unitless (as the case with specific gravity). Crude Oil API Gravity conversion to 60F from observed temperature as per ASTM 5A and volume Correction VCF as per Petroleum tables ASTM 6A using an App developed. The App developed converts a) API Gravity at 60 Deg F from observed API Gravity and temperature and b) calculates the bulk volume from natural to volume at 60 deg F, US barrels at 60 deg F for Crude oil cargoes. If an oil has 26.5 deg of API, then its specific gravity is calculated as s = 141.5 / ( 131.5 + 26.5 ) s = 0.8956
